NEET BIOLOGY

Detailed explanation-1: -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-2: -A chloroplast is a type of plastid (a saclike organelle with a double membrane) that contains chlorophyll to absorb light energy.

Detailed explanation-3: -In the chloroplast, chlorophyll is the pigment that absorbs the sunlight. Chlorophyll is typically packed into stacks of membranes (called grana); it is in the grana where some of the sunlight is absorbed.

Detailed explanation-4: -The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH.

Detailed explanation-5: -The chloroplast absorbs the energy in sunlight and uses it to produce sugars. Chloroplasts play an important part in the process of photosynthesis in some organisms.
