Question

name the two cell organelles which are bound by a double layered membrane give one function of each

Answer 1

1)mitochondria is having double layered membrane the main function of it is to synthesis energy rich molecule ATP.
2)Golgi body is also double membrane the main function of it is to modify and transport protein that comes from ER, it takes part glycosidation and glycosylation
3) plastid is also double membrane organelles which helps in photosynthesis (chloroplast) and in food storage (leucoplast)
4) endoplasmic reticulum is double membrane and helps in Protein synthesis

Answer 2

Plastids and mitochondria are those two organelles which are bounded by double membranes .

Plastids : These are of 3 types. Namely the :

• Chloroplast
• Chromoplast
• Leucoplast

The main function of plastids is to provide different colours to different parts of different organs.

Mitochondria :

They are the house of energy.

Here ATP is formed in the form of energy.

ATP : Adenosine Triphosphate.
