Question

chloroplastids structure and function

Answer 1

chloroplast is an organelle unique to plant cells that contains chlorophyll (which is what makes plants green) and is responsible for enabling photosynthesis to occur, so that plants can convert sunlight into chemical energy. So basically, without chloroplasts, plants could not create energy, and without them, humans would have no food and we would perish, so thank you chloroplasts!

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 an empty intermediate space in between. Inside the chloroplast are stacks of thylakoids, called grana, as well as stroma, the dense fluid inside of the chloroplast. These thylakoids contain the chlorophyll that is necessary for the plant to go through photosynthesis. The space the chlorophyll fills is called the thylakoid space.
