The Chloroplast

Disc-shaped organelles found in some plant cells.

It is bound by a double membrane.

Internally, it consists of layers of membranes known as lamellae suspended in an aqueous matrix called stroma.

Lamellae may at certain intervals forms several layers of membranes grouped together to make granum (plural – grana).

Granum contains chlorophyll which trap light energy for photosynthesis.
