The organelle responsible for photosynthesis in plant cells is the chloroplast.

Quick Scoop

  • Chloroplasts are specialized structures in plant cells (and some algae) where photosynthesis takes place, converting light energy into chemical energy stored in glucose.
  • Inside chloroplasts, pigments like chlorophyll capture light, and reactions in the thylakoid membranes and stroma produce energy-rich molecules and oxygen as a by‑product.
  • Chloroplasts are part of a broader family of plastids, but they are the member specifically adapted and structured for photosynthesis.
