Answer 2

Mitochondria's functions :- Mitochondria are called the powerhouses of the                                               cell. The energy needed for different chemical activities required for life is released by mitochondria in the form of ATP (Adenosine triphosphate) molecules. ATP is called the energy currency of the cell. The body uses energy accumulated in ATP for forming new chemical compounds and for mechanical work. Mitochondria contain two membrane is quite porous whereas the inner membrane is deeply folded. these folds create a huge surface area of ATP-generating chemical reactions.
Mitochondria are unique organelles in the sense that they have their own DNA and ribosomes. Hence, mitochondria are able to prepare some of their own proteins.


Chloroplast functions :- Plastids having the pigment chlorophyll are called                                              chloroplasts. Chloroplasts are essential for photosynthesis. Inside chloroplasts are thylakoids, called grana and stroma. These thylakoids contain the chlorophyll that is essential  for the plant in photosynthesis. chloroplasts also contain several yellow or orange pigments in addition to chlorophyll.
