In what organelle does photosynthesis occur?
A
mitochondria
B
stomata
C
xylem
D
chloroplast
Explanation: 

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. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.

Detailed explanation-2: -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-3: -Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.

Detailed explanation-4: -Photosynthesis primarily takes place in the specilised structures called chloroplasts that have chlorophyll present in them. It is the chlorophyll that absorbs light energy from the sun. The leaves contain majority of the chloroplast which absorbs sunlight for the process of photosynthesis to take place.
