Question

What are the steps involved in photosynthesis?

Answer 1

Hint: Sunlight absorption. Conversation between light energy and chemical energy from food. Water Photolysis. CO2 reduction in carbohydrates such as glucose that are later processed in the form of starch.

Complete answer:
 -The sunlight in the leaves is first trapped by chlorophyll (the chemical that leaves green plants and traps sunlight). (The sunlight provides the plants with energy.)
- Next, the sunlight gives the plant energy to begin the process of food making.
- Then the leaves are sucked up by the roots and then the leaves combine carbon dioxide, nutrients, and water to make their food (sugar).
- Their waste (oxygen) is eventually thrown out.
Two of the three products needed for photosynthesis are carbon dioxide and water. The water molecules go through the root cells, and through the vascular tissue and through the stem, and to the leaves after the plant obtains water from the soil. It absorbs carbon dioxide from the air. Air flows through the stomata and the kind of spongy mesophyll cells into air spaces. In order to break the water into hydrogen and oxygen, the plant then uses the energy from the sun; then the oxygen is released into the air, while the hydrogen is used to make a special compound called ATP and NADPH. Hydrogen atoms from NADPH are combined with carbon dioxide from the air to create glucose from a simple sugar through a subsequent sequence of steps (which just happen to require no light). By breaking down the ATP that was generated earlier, the energy needed for the synthesis of glucose is given.

Note: It isn't the production of oxygen. The primary purpose of photosynthesis is to transform solar energy into chemical energy for future use and then store the chemical energy. The living systems of the earth, for the most part, are driven by this mechanism.
