NEET BIOLOGY

Detailed explanation-1: -The carbon-fixation reactions, which begin in the chloroplast stroma and continue in the cytosol, produce sucrose and many other organic molecules in the leaves of the plant. The sucrose is exported to other tissues as a source of both organic molecules and energy for growth.

Detailed explanation-2: -Carbohydrate production occurs in the stroma of the chloroplast. The stroma is the liquid filled space between the thylakoid and inner membranes. The stroma is the site of the Calvin cycle which is the process by which carbohydrate synthesis occurs.

Detailed explanation-3: -Green plants manufacture glucose through a process that requires light, known as photosynthesis. This process takes place in the leaf chloroplasts.

Detailed explanation-4: -Carbohydrates. Chloroplast is the organelle for photosynthetic carbon assimilation in plant cells. Carbohydrates assimilate in chloroplasts during the day, with some stored as starch, or degraded to supply sugars for growth at night.

Detailed explanation-5: -Leaves That Breathe People breathe oxygen in and carbon dioxide out, but for a plant to make carbohydrates, the leaves take in carbon dioxide through the stomata on the leaf surfaces. From the stomata, the mesophyll cells use the carbon dioxide to combine it with water and light for photosynthesis.
