Photosynthesis Location

Photosynthesis takes place in chloroplasts, specialized organelles in plant cells.

Chloroplast Structure

Chloroplasts have stacked membranes (thylakoid) and a fluid-filled space (stroma).

Thylakoid Definition

Thylakoids are the sac-like membranes within chloroplasts, containing chlorophyll.

Grana

Stacks of thylakoids inside chloroplasts.
