Question

Give the steps in squerce for the process of photosynthesis

Answer 1

By definition, photosynthesis is a process by which photoautotrophs convert the energy derived from the Sun into usable chemical energy. Light, water, chlorophyll, and carbon dioxide are the basic requirements for this process.
Step 1: Carbon dioxide in the atmosphere enters the plant leaf through stomata, i.e., minute epidermal pores in the leaves and stem of plants which facilitate the transfer of various gases and water vapor.
Step 2: Water enters the leaves, primarily through the roots. These roots are especially designed to draw the ground water and transport it to the leaves through the stem.
Step 3: As sunlight falls on the leaf surface, the chlorophyll, i.e., the green pigment present in the plant leaf, traps the energy in it. Interestingly, the green color of the leaf is also attributed to presence of chlorophyll.

Answer 2

In easy language,

The three events that occur during the process of photosynthesis are:
(i) Absorption of light energy by chlorophyll.
(ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
(iii) Reduction of carbon dioxide to carbohydrates.
