Question

Find out the odd one (with reference to
number of unit membrane)
A) Mitochondria
B) Nucleus
C) Choroplast
D) Ribosome

Answer 1

D) Ribosome is the correct answer

Answer 2

The ribosome lacks a cell membrane.

• A cell membrane is an outermost layer in animal cells, except plants and microorganisms that have a cell wall.

• All the organelles mentioned in this context require a cell membrane for the synthesis of different products.

• The cell membrane is composed of the phospholipid bilayer. This provides the fluidity nature to the cell membrane.

• In the case of ribosomes, they act as a mediator in the production of proteins.

• This is the reason why ribosomes lack a cell membrane.
