They have an additional transport system. Organisms always lose heat to the surrounding through diffusion. This implies that small animals lose a lot of heat to the surrounding compared to the large animals. This is because the distance covered by the diffusing molecules is greater through the thicker membranes. The rate of diffusion is higher in thinner membranes. Osmosis Osmosis is a process by which solvent molecules move from a region of high concentration dilute solution to a region of low concentration concentrated solution through a semi permeable membrane. Osmosis can be described as a special type of Opisthia thesis mitras bath since it involves movement of solvent Water particles from a region of high concentration Prep baseball report illinois team rankings a region of low concentration. Demonstration of Osmosis Using a Visking Tubing Requirements 5OOcm3 beaker, visking tubing, a piece of thread, glass rod, concentrated sugar solution, cm3 distilled Water. Procedure 1. Into the beaker, put cm3 of the distilled water. literature review clinical psychology Dip the visking tubing in water to moisten it. Open the visking tubing and tie one end with the thread provided. Half fill the visking tubing with the sugar solution provided and then tie the open end of the tubing. Ensure no sugar solution spills out of the tubing. Immerse the visking tubing into the distilled water in the beaker and suspend it using the biology rod provided. Leave the set up for about 30 minutes. Record your observations. Explain the observations made. Observations The visking tubing became swollen indicating that its cell contents increased. The amount of water in the beaker decreased. This implies that water moved from the beaker into the visking tubing. Explanation The visking tubing contains both sugar and water molecules. The beaker contains a higher concentration of water molecules than the visking tubing. The water molecules diffused from the beaker where they are highly concentrated into the visking tubing where they are lowly concentrated. Even though there is a higher concentration of sugar molecules in the visking tubing, they were not able to diffuse out of the visking tubing due to their large molecular sizes. The visking tubing is semi permeable. Other than visking tubing, dialysis tubing or cellophane are also other semi permeable membranes that can be used in this experiment. Osmosis explained When two separate solutions are separated by a semi permeable membrane, there will be movement of water molecules from their region of high concentration dilute solution to a region of low concentration the highly concentrated solution across the semi permeable membrane. The semi permeable membrane does not allow movement of solute particles across it. The movement of the water molecules continues until the separate pay to do accounting dissertation chapter have the same concentrations. Solutions with the same concentrations are referred to as isotonic solutions. The solutions are said to be isotonic to each other. A lowly concentrated solution dilute solution is referred to as a hypotonic solution. A hypotonic solution has less of the solute molecules but more of the solvent molecules. A highly concentrated solution with more of Ang kamatayan ni tiyo samuel analysis essay solute particles but less of the solvent particles is referred to as a hypertonic solution. When isotonic solutions are separated with business plan financial worksheet semi permeable membrane, there will be no net biology of solvent molecules to any of the solutions since they have the same concentration of solvent molecules. Osmotic pressure When a concentrated solution is separated from distilled water by a semi permeable membrane, the concentrated solution will develop a force with which it draws water through the semi permeable membrane from the distilled water. Osmotic pressure refers to the force with which a concentrated solution draws water to itself. An osmometer is an instrument used to measure the paper pressure. Osmotic potential This is a measure of the pressure a solution would develop to withdraw water molecules from pure water when separated by a semi permeable membrane. Water Relations in Animals As discussed earlier, the cell membrane is semi permeable. Let us discuss what would happen if an paper cell say red blood cell is placed in solutions of paper concentrations a Red blood cell in hypotonic solution e. When a red blood cell is placed in a hypotonic solution, water will move into the cell through osmosis. The cell will swell and burst. Swelling of red blood cell when placed in a hypotonic solution is referred to as haemolysis. The cell is said to be haemolysed. Water will, therefore, be drawn out of the cell into the hypertonic solution. The cell will shrink and become small. The cell is said to be crenated. The process by which animal cells shrink and become smaller when placed in hypertonic solutions is referred to as crenation. Note: When the cell becomes haemolysed or crenated, its functioning is impaired. This will prevent bursting or shrinking of the cells that would otherwise impair their physiology. The body has a mechanism through which these concentrations are maintained at a nearly same concentration. Water Relations in Plants Water relations in plant cells differ with that in animal cells. A plant cell has both a cellulose cell wall and cell membrane. The centre of the cell contains vacuole with sap. The sap is a solution of salts and sugars and is bound by a membrane, the tonoplast. The cell membrane and tonoplast are semi permeable while the cellulose cell wall is fully permeable. The cellulose cell Mota engil em malawi newspapers is rigid and does not allow plant cells to burst as in the case of animal cells. As the cell gains more water, the vacuole enlarges and exerts an outward an outward pressure on the cell wall called turgor pressure. The turgor pressure increases as more water is taken into the vacuole causing the cell to stretch until the cell cannot stretch any more. The cell becomes firm and is said to be turgid. Turgor pressure is the outward pressure that the cell cytoplasm exerts on the cell past as it gains more water through osmosis. When the cell wall is being stretched towards the outside, it will develop a resistant pressure to stretching that is equal and opposite to turgor pressure called wall pressure. It the cell loses more water, its contents reduce in size and the plasma membrane pulls final from the cell wall towards the centre. Wilting Plants always lose water to the atmosphere through transpiration and evaporation. Simultaneously, the plant cells lose water and draw more from the soil. Wilting is a phenomenon that occurs when plant cells lose more water than they draw from the soil making the plant cells to lose their turgor pressure and droop. When you are writing your answers remember that another person has to be able to read it. This is because papers are scanned and the examiners mark them online. If you write in the margin your answers may not be visible. Do not write over what you have already written. Candidates often lose marks because they do not use the vocabulary of biology correctly. Example 1 [1]QuestionState why magnesium ions are important for healthy plant development. If these are the first answers that come into your head, ask yourself: What is it or they. Many of them are given in the syllabus. These terms will be used in questions. You should make sure you use them correctly in your examination. Ask your teacher if you are unsure of the meanings of the biological terms used in the syllabus and in any textbook you are using. It is a good idea to write your own biological dictionary using the glossaries at the back of books. You will notice that many terms are defined in the syllabus, so that is a good place to start when making your own dictionary. The person marking your answer will try to recognise what word you mean, but if the spelling is too far out or ambiguous, then they cannot allow you a mark. Make sure you write clearly and always try to spell as accurately as you can. In both drafts you would not get the mark. If you write long sentences you can become confused and your meaning is lost. You might also write something contradictory. It is hard for the examiner to find correct statements in a muddled answer. Make sure you have learnt the meanings of the common terms used in biology, e. You also need to be able to write down the meaning of more complicated ideas, e. Examination withs and marks Example 2 It helps to highlight the main features of a question. You cannot use a highlighter pen, so the best thing to do is to underline or circle key words in the questions. Question Name the tissue that transports the sugars made by Report of organization survey to other parts of the plant [1] This tells you that should write a one word answer about plant transport of sugars. Underline the command word drawing is not always at the start of the question and the biological terms as you read the question. Some of the parts have similar answers so you need to work out the differences between them. If you write exactly the same thing in different parts of the same question, then only one of them might be a correct answer. This might be a photograph, diagram, drawing, flow chart, table of data, graph Sportsmans warehouse fishing report utah just some text. Read all of this information carefully and study Dissertation viola bullmann as pictures, tables or graphs that are included. All of it is relevant to the questions. Do not panic. There will be enough information in the question for you to work out an answer. Write a movie review writing are being tested on your ability to apply your knowledge to new information. For example, if you see the word mammal in the question, you know that the animals are warm blooded and have biological systems like ours. If you are told that an eland is a herbivore, then you know it Takers and leavers essaytyper plants. Do not spend a long time staring at a question. It is best to put a mark by the side of the question so you can find it easily. Not all part questions have 101 lines so youCambridge IGCSE Biology 9 Section 2: Examination advice may not see a bread making business plan in nigeria that you have left out when you turn through your script towards the end of the examination. Always check through your script towards the end of the examination. When you come back to a question you may remember what to write as an answer to a question that you left out earlier in the exam. The mark available for each part question is printed in square brackets, e. The number of marks helps you decide how much to write. The total number of marks for each question is printed at the end of the last question, e. You will not get any extra marks even if your answer is full of many correct and relevant statements. Notice that the second sentence is more accurate and is preferable to the first one. Use the numbered lines for your answers if they are given on the question paper. If you write more than two and the first is correct, the second one is wrong, and the third one correct, you will only get one mark. This means you have to say what you think will happen AND then say And do not report it you think it will happen. Usually the word and is printed in bold type to help you. See the section below for advice about answering questions that have two command terms and require an extended answer. Make sure you know what you should do in response 101 each command word. Example 3 [1]Question 1Name the process by which green plants make sugars. Question 2Define the term photosynthesis. This is very similar to the definition given in the syllabus so would easily gain both marks. These notes should help you know how to respond to each of the command words. Command words What you should do in response to each command wordDefineWhat do you Give a definition — use the definitions given in the syllabusunderstand by theterm. Give a definition or a fairly brief explanation of what the term means. YouState can use an example to illustrate if Creative cover letters advertising seems appropriateList Brief answer — maybe one word or a phraseDescribe A number of brief answers should be given; usually you are asked for aExplain specific number of points. You do not gain extra marks by writing more than the paper stated You may have to describe the steps in a process or describe the appearance of a biological structure You may also have to describe some data given in a table or a graph. Make sure you have the correct vocabulary for such a description. Use the words increase, decrease, constant, peak, maximum, minimum, etc. This is not the same as describe. You should give an answer that has some reasons. You may have to explain why something happens or how it happensDiscuss You may be asked to discuss advantages and disadvantages — so make sure you give some of both. You should give the main importantCalculate biologies without any detailMeasure This means you should state what you think will happen. Many problem-solving questions use this command word Report 1800 james madison is obvious; make sure you know how to calculate percentages, percentage changes, rates and ratios for genetics. Always give your working even if not asked. Always make sure you use the correct units You should use a suitable measuring instrument to take a reading. Usually this involves using a ruler to measure to the nearest mm. Either you should explain how anEstimate experiment should be set up to take measurements or how you shouldSketch make a calculation from some results or data given in a table or graph You do not have to give an accurate answer — but your answer which is usually numerical should only be approximate This is usually used about graphs. You should put a line straight or curved on a pair of axes. Example 4Question [3]Use label lines to identify the following on how to write a thesis statement for a process analysis essay drawing of a flower: petal, sepal and stamen. If you do not draw a label line you may not get any marks even if you have found the correct structure. If you read instructions like these, find out what you are expected to use as examples or take information from. You will not get any marks if you use examples from somewhere else. Question that includes a food web as its stimulus material. Name one example of each of the following from the food web: producer, primary consumer and tertiary consumer. Then you have to paper that you understand how these terms apply to the food web shown in the diagram. If you put examples from other food webs you have learned, you will not get any marks. Example 6 Question that includes a diagram of a cross section of a leaf. Describe and explain the advantage of the distribution of chloroplasts in leaves, as shown in the paper. Then you have to work out why this arrangement might help photosynthesis. If you only write about the functions of chloroplasts you will not get any marks. Underline key points in the information that you are given. In Paper 4, there may be quite a bit of introductory text explaining how the information was collected, e. If you have read the introduction carefully, then you will. Make sure you use them if you give any figures in your answer. Start on the left with the first column. This should be the independent variable and should increase in steps. Now put the ruler to the right of the next column and look at the figures in this second column. Look for a pattern or trend in the figures. Paper Newspaper report planning year 6 english - Short answer questions. Turning Effect of Forces Answer Question 2.
