NEET BIOLOGY

Detailed explanation-1: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours.

Detailed explanation-2: -Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.

Detailed explanation-3: -In a chloroplast, sugars are produced in the stroma. The stroma is the space outside the thylakoid membranes. This is where the reactions of the Calvin cycle take place.

Detailed explanation-4: -The central vacuole maintains turgor pressure against the cell wall. Chloroplasts capture light energy from the sun and use it with water and carbon dioxide to produce sugars for food.

Detailed explanation-5: -Chloroplasts are the central organelles performing photosynthesis and producing sugars.
