Question

Define photosynthesis ​

Answer 1

The process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

Answer 2

Answer:

The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis.

Explanation:

Photosynthesis the term photosynthesis was given by Charles Reid Barnes in 1883. The cells of green leaves and young stems of plants contain numerous green structures called chloroplasts. The chloroplasts are green because of the presence of a green pigment called chlorophyll . It is the chlorophyll that traps energy from sunlight. The leaves take in carbon dioxide from the air through tiny pores called stomata (singular : stoma) . these pores are present on the lower side of the leaves. The stomata are surrounded by guard cells. These guard cells control opening and closing of the stomata. The water is absorbed from the soil by the roots hairs present in the roots.
