Q

Describe everything about Mitochondria?
What is function of mitochondria?
What is the adaptation?

A

Mitochondria is double membrane.
Function: Site of Aerobic Respiration

Adaptation: Is folded called Cristae which gives it a large Surface Area so rate of Aerobic Respiration maximally increased.

Q

Contrasts Eukaryotic and Prokaryotic cells?

A

Eukaryotic cells are membrane-bound organelles and prokaryotic cells are not membrane-bound organelles.
