Chloroplast

Vedclass · Answer

(B) The chloroplast is a type of plastid found in plant cells and algae. It consists of a double membrane envelope and an internal space called the stroma. Inside the stroma,there are flattened,sac-like structures called thylakoids,which are stacked to form grana. The stroma lamellae are the membrane channels that connect the grana of different thylakoid stacks. Therefore,both grana and stroma lamellae are integral components of the chloroplast.
