Chloroplast: Structure and Function. Present in plants and certain algae, chloroplasts are a type of membrane-bound plastids. They harbor light-harvesting pigments including chlorophyll, and serve as the site for photosynthesis as well as some reactions of photorespiration. Read on this article to know more.
The cytoplasmic structure that is only found in plant cells is the chloroplasts. The chloroplasts are responsible for capturing and storing energy from sunlight to use during photosynthesis.
Describe the structure of a chloroplast, listing all membranes and compartments. A double membrane surrounding a dense fluid called the stroma and elaborate membrane system called thylakoids, enclosing the thylakoids space.
Structure of Chloroplasts. Chloroplasts, like mitochondria, are oval-shaped and have two membranes: an outer membrane, which forms the external surface of the chloroplast, and an inner membrane that lies just beneath. Between the outer and inner membrane is a thin intermembrane space about 10-20 nanometers wide.
Structure of Chloroplasts. Chloroplasts can be found in the cells of the mesophyll in plant leaves. There are usually 30-40 per mesophyll cell. The chloroplast has an inner and outer membrane with ...

Start studying Chloroplast structure and function. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Ultra structure of Chloroplast: Chloroplast is also a double membrane bound organelles. Chloroplasts are mainly found in the cells of leaves of green plants, chloroplast are limited by, a smooth outer membrane which regulates the transport of material between the cytoplasm and the interior of the organelle.
The only chloroplast structure that can considered analogous to it is the internal thylakoid system. Even so, in terms of "in-out", the direction of chloroplast H + ion flow is in the opposite direction compared to oxidative phosphorylation in mitochondria.
(b) Belt-shaped chloroplast. Example- Ulothrix. (c) Cup-shaped chloroplast. Example- Chlamydomonas. (d) Star-shaped chloroplast. Example- Zygnema. Fig: Different parts of chloroplast (a simplified figure seen through the electron microscope) Structure of chloroplast: The structure of chloroplast is very complicated.
