Question

what is a membrane,which bound structure containing of 3 membranes​

Answer 1

Answer:

Chloroplast i is a membrane bound structure containing of 3 membranes. The third layer forms stacked sac like structures called Grana ii. It is the site for trapping solar energy.

Explanation:

The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures.

Answer 2

Definition of membrane and name is given below -

• Membrane or biological membrane is a bilayer structure present on cell and various organelles to provide semi permeability. The bi-lipid layer consists of phospholipid head molecule and fatty acid tails.

• Structure containing three membranes is chloroplast. Chloroplast has double layer membrane with outer membrane and inner membrane. In addition, chloroplast also contains thylakoids, which are membrane bound compartments as well. The chloroplast aids in the process of photosynthesis.
