Explanation / Answer

2) Dependency of most of organisms are depend on the photosynthesis because most of the green plants use light energy to convert carbon dioxide and water to glucose andoxyegen as byproduct. Oxygen is neded to most of the organisms. Hence the dependency of the most of the organisms is photosynthesis.

3)

a) Key events of light reactions:

In this reaction the light energy get converted to chemical energy. Which is temporary stored in ATP and the energy carrier molecule NADPH. This process occures in the thylakoid membrane.

b) Key events of the independent reaction:

This reaction is also called as calvin cycle reaction because the CO2 and chemical energy provided by the ATP and NADPH to form the organic compounds. Carbon fixation is occurs with the help of rubisco (enzyme) which facilates the regeneration of five carbon compound RuBP.

4.

a) The primary photosynthetic tissue is the mesophyll.

b)The leaf has the opening for gas exchange are called as the Stomata.

c) The leaf's Cuticle is the waxy coating that reduces water loss.

d) The main photosynthetic organ of a geranium plant is composed of two parts the leaf and Stem.
