Question

A student was looking at a cell under a microscope. He noted down his observations.
A. A well defined nucelus.
B. Large ribosomes.
C. A cell wall.
From which of the following is the cell likely taken from?

• A. Euglena
• B. Banana leaf
• C. Mycoplasma
• D. Human cheek cells

Answer 1

The correct option is B Banana leaf

The given observations like well-defined nucleus, large ribosomes, etc., are characteristics of an eukaryotic cell. Prokaryotes normally do not have a well defined nucleus or large ribosomes. The difference between a eukaryotic animal cell and a plant cell is the persence of a cell wall. Since plants are immobile, they have an extra layer of protection around their cell membrane called cell wall. So the right answer is banana leaf.
