In which organelle does photosynthesis take place? stoma vascular bundle mitochondrion chloroplast

The correct answer is- Chloroplast.

Photosynthesis is a process of formation of food (that is a carbohydrate) in green plants and algae by using CO2 (carbon dioxide) and water in the presence of sunlight.

This process takes place in a specialized membrane bound organelle that is termed as chloroplast.

This organelle contains a green pigment, chlorophyll, which absorbs the energy from sunlight and convert it into chemical energy in the form of ATP and NADPH.

The chemical energy is then utilized in the formation of carbohydrate (glucose) in the next phase, which is a light independent phase.

Thus, chloroplast is the right answer.
