Educate to Elevate Igniting the Flame of Learning 1  Root Hair Cells 2  Transpiration 3 4 5  Factors Affecting Water Loss Diffusion rate is affected by: Surface area (the higher the surface area, the greater the rate of diffusion). Difference in concentration (the greater the concentration gradient, the higher the rate of diffusion). Length of the diffusion path (the greater the length, the lower the rate of diffusion). 6  1- in the green parts/in the leaves and stem 2- because they contain chlorophyll 3- because they are not green/do not receive 7 light 8 9 10 11 12 13  1 -The carbon dioxide particles have kinetic energy. They are in constant, random motion. By chance, some of them will go into the leaf through the stomata. Some will also come out. But, overall, more will go in than out because there are more of them outside the leaf than inside it. 2- Some of the oxygen diffuses out of the leaf. Some of the oxygen is used in respiration. 14 15 16 17  3- Plants get their protein by using the carbohydrates they make in photosynthesis and adding nitrogen to them to make proteins. Animals get their protein by feeding on plants and/or other animals. 4- Nitrate and magnesium are both needed for making chlorophyll, so a shortage of either of them makes leaves go yellow. Nitrate is also needed for making proteins, but without magnesium the plant cannot photosynthesise, so it has fewer carbohydrates to make proteins from. A lack of either nitrate or 18 magnesium reduces growth
