The chloroplast structure within a plant cell is composed of the following parts:

  • Inner and outer membranes
  • Stroma
  • Thylakoid membrane which contains the photosystems
  • Granum which is a stack of thylakoids
  • Stroma lamellae which are flattened sacs inside the chloroplast

The inner membrane contains enzymes and proteins that are involved in photosynthesis while the outer membrane acts as a barrier that prevents the movement of large molecules. The stroma is the space between the inner and outer membranes and is filled with a variety of enzymes and proteins that are involved in metabolic processes. The thylakoid membrane contains the photosystems which are responsible for absorbing sunlight and converting it into chemical energy. The granum is a stack of thylakoids and the stroma lamellae are flattened sacs inside the chloroplast that contain enzymes and proteins involved in the production of carbohydrates.

Why chloroplast is said to be cell within a cell?

A Chloroplast is sometimes refered to as a "cell within a cell" due to the fact it has its own membrane is separated from the rest of the cell. This may also be due to having small organelles within the Chloroplast.
