You have isolated a cell under a microscope. Which of the following observations would be sufficient to identify it as a eukaryotic cell?

A. It has a plasma membrane

B. It has chloroplasts

C. It lacks a nucleus

D. It uses ATP

E. It has DNA

Solution

It is a very well known fact that most distinguishable feature among eukaryotes and prokaryotes is the presence of membrane bound organelles in the eukaryotes while these are absolutely absent in the prokaryotes. Membrane bound organelles such as nucleus, lysosomes, mitochondria, peroxisomes, chloroplasts, golgi apparatus etc are characteristic features of eukaryotic cells. However, a plasma membrane is found in both prokaryotic and eukaryotic cells. Both the cell types contain DNA as their genetic material and utilize ATP for energy expenditure.

Thus, the correct answer is choice B, presence of chloroplasts.
