Learning ObjectivesYou should be able to:
(a) identify and label the cellular and tissue structure of a dicotyledonous leaf, as seen in transverse section under the microscope and describe the significance of these features in terms of their functions, such as the • distribution of chloroplasts in photosynthesis • stomata and mesophyll cells in gaseous exchange • vascular bundles in transport (b) state the equation, in words and symbols, for photosynthesis (c) describe the intake of carbon dioxide and water by plants (d) state that chlorophyll traps light energy and converts it into chemical energy for the formation of carbohydrates and their subsequent uses (e) investigate and discuss the effects of varying light intensity, carbon dioxide concentration and temperature on the rate of photosynthesis (e.g. in submerged aquatic plant) (f) discuss light intensity, carbon dioxide concentration and temperature as limiting factors on the rate of photosynthesis |
