Explain the importance of photosynthesis to life on Earth.
Describe briefly important events that define the history of plant life on earth.
Identify and label the cellular and tissue structure of a dicotyledonous leaf, as seen in transverse section using the light 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
State the equation, in words and symbols, for photosynthesis.
Describe the intake of carbon dioxide and water by plants.
State that chlorophyll traps light energy and converts it into chemical energy for the formation of carbohydrates and their subsequent use.
Describe briefly the light dependent reaction and the light independent reaction in photosynthesis. [No details of the reactions needed]
Investigate and discuss the effects of varying light intensity, carbon dioxide concentration and temperature on the rate of photosynthesis.
Discuss light intensity, carbon dioxide concentration and temperature as limiting factors on the rate of photosynthesis.
Photosynthesis allows producers to convert light energy and inorganic molecules into chemical energy and organic molecules, which are transferred up the food chain when they are consumed
Photosynthesis also produces oxygen into the air for cellular respiration by most living things
Plants which are not eaten but have died millions of years ago can have their remains be converted to fossil fuels; They are burned in the present to release energy stored in them
