NEET BIOLOGY

Detailed explanation-1: -In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Detailed explanation-2: -Chloroplast is concentrated mostly in the parenchyma cells of the leaves. Thus, photosynthesis takes place in the plant cells that have chloroplasts with chlorophyll pigment.

Detailed explanation-3: -The primary cellular structures that ensure photosynthesis takes place are chloroplasts, thylakoids and chlorophyll. Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves.

Detailed explanation-4: -The cells of a leaf are sandwiched in between two layers of epidermal cells, which provide the leaf with a waxy, nearly impermeable cuticle that protects against water loss. The only way for gases to diffuse in and out of the leaf is though small openings on the underside of the leaf, the stomata.

Detailed explanation-5: -In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.
