Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle is the site of photosynthesis?
A
Chloroplast
B
Mitochondria
C
Either A or B
D
None of the above
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: -Chloroplasts are found in all green plants and algae. They are the food producers of plants. These are found in mesophyll cells located in the leaves of the plants. They contain a high concentration of chlorophyll that traps sunlight.

Detailed explanation-3: -Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

Detailed explanation-4: -Many of the reactions involved in cellular respiration happen in the mitochondria. Mitochondria are the working organelles that keep the cell full of energy. In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.
