Question

Jane is observing a cell under an electron microscope. She identifies an organelle having an outer and an inner membrane. She also notices that the outer membrane is smooth while the inner one is highly folded. Which organelle is Jane observing?

Select one of the options below as your answer:

A) Mitochondria

B) Golgi bodies

C) Nucleus

Answer 1

The organelle that Jane was observing was a mitochondria. A mitochondria always has a smooth outer membrane and the inner membrane is folded. The correct answer is A.

Answer 2

The correct option is A.

Mitochondria is one of the organelles that are found in living cells and it is the one responsible for the production of ATP, which is the source of energy that is usable by the cells. Mitochondria is designed in such a way that, it will be able to carry out its functions efficiently. Mitochondrial has two membranes, one at the outside and the other one at the inside. While the outer membrane is smooth, the inner one is highly folded and it formed a structure called cristae. The folding of the inner membrane serves to increase the surface area inside the mitochondria.
