All chloroplasts have at least three membrane systems—the outer chloroplast membrane, the inner chloroplast membrane, and the thylakoid system. Chloroplasts that are the product of secondary endosymbiosis may have additional membranes surrounding these three. read more

Chloroplasts are structured in an ellipsoid shape. They contain a double membrane, which has two layers that serve different functions. The outer layer of the membrane helps protect the chloroplast from harm and it is more permeable than the inner layer. read more

A chloroplast is a type of plant cell organelle known as a plastid. Plastids assist in storing and harvesting needed substances for energy production. A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis. read more
