explain the structure of a choloroplast with the help of a diagram.

- The chloroplast is a structure which is surrounded by two unit membranes separated from one another by a space called periplastideal space. The heterogeneous nature of chloroplast is due to the presence of disc-like structures i.e., grana, in a colourless matrix called stroma. Grana are the sites for the light reaction and stroma is the site for the dark reaction of photosynthesis. Each granum is made up of a stock of closed compartment called thylakoids. Each thylakoid consists of two parallel membranes joined at their margins. The membranes of thylakoids contain the layer of particles called chlorophyll. In stroma, there are many membranes running parallel to each other throughout the length of chloroplast which is called lamellae. The stacks of thylakoids sacs are connected by stroma lamellae. Each chloroplast contains nearly 40-60 grana embedded in the

Answer 2

Answer:

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.
