Notes from NEET topper

Structure of Chloroplast:

  • Chloroplasts are double-membraned organelles found in plant cells.
  • They contain a green pigment called chlorophyll, which captures light energy for photosynthesis.
  • Chloroplasts have thylakoid membranes arranged in stacks called grana, where light-dependent reactions occur.
  • The stroma is the fluid-filled region where the Calvin cycle (dark reactions) takes place.
