Answer 1

Answer:

• the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
• Raw materials for photosynthesis is The raw materials of photosynthesis are water, carbon dioxide, sunlight and chlorophyll
• Leaves are adapted for photosynthesis and gaseous exchange. They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. ... The cells inside the leaf have water on their surface
• Though the final product of photosynthesis is glucose,
• Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces.

Answer 2

Definition of photosynthesis -

The process of making food by Green plants (autotroph) is called photosynthesis. For performing photosynthesis water, sunlight and carbon dioxide are used by the plants.

They take sunlight from sun, water from soil and carbon dioxide gas from the air present around us. The leaves have small holes called stomata which allows air to enter the plant. Leaves also contains chlorophyll in them which traps sunlight and helps in making food. Roots of plants absorbs water and Minerals from the soil and transfers them leaves through stem.

The chemical equation for the photosynthesis

is -

carbon dioxide + water -> glucose + oxygen + energy
