in what organelle does photosynthesis take place?

Photosynthesis takes place in the chloroplasts , a specialized organelle found in plant cells and many algae.

Quick Scoop

  • Chloroplasts are tiny green structures inside plant cells where light energy is converted into chemical energy (glucose).
  • Inside chloroplasts, the light reactions occur in the thylakoid membranes, and the sugar-making (Calvin cycle) happens in the stroma.
  • These organelles are packed into leaf mesophyll cells, which is why leaves are the main sites of photosynthesis in plants.

In short: when asking “in what organelle does photosynthesis take place?”, the answer is chloroplasts.
