Answer:
There are many cell organelles which are membrane-bound, The two organelles which have double membrane are the mitochondria and choloroplast.
Mitochondria
Are sausage or cylindrical-shaped organelles found in cytoplasm
Are the sites of aerobic respiration (complete breakdown of glucose to release energy)
Number and size varies.
Has 2 membranes; outer membrane and inner membrane
Inner membrane forms a number of infoldings called the cristae
Cristae contains many enzymes required for forming ATP (storage form of energy inside a cell)
Fluid-filled space inside the mitochondria is called the matrix
Matrix contains a circular DNA, few RNA molecules and ribosomes (70S).
Are also called the powerhouses of the cell (because they generate energy required for the cell and store it in the form of ATP)
Are semi-autonomous (They have their own DNA and replicate on their own and can also synthesize most of its proteins)
Chloroplast
They are mainly present in the in leaf epidermal cells.
They are cylindrical-shaped organelles
They are the sites of photosynthesis
They have 2 membranes; outer and inner membrane
The fluid-filled internal space is called the stroma
The stroma contains thylakoids which contain the pigments chlorophyll and carotenoids.
The stroma also contains a circular DNA, few RNA molecules and ribosomes (70S).
