Question

Onion cells and cheek cells are the examples of prokaryotic cell
A) True
B) False

Answer 1

Hint: The world has started from the primitives having a single cell with the simplest organization. Due to the changes in the environment, the body complexity increased and the organizations became tough. These organisms were then placed in the eukaryotes category.

Complete answer:
Let’s first know about these cells.
a. Bacteria are the most primitive organisms known to us. They are the prokaryotic cells. They do not have organelles bounded with membrane as they do not have a complex body. They even lack membrane around the nucleus. Onion cell is a eukaryotic cell with well-defined membranes around the organelles. It also has a well-defined and membrane nucleus. Cheek cell- contains membranous organelles, onion peel cell-no membranous organelle: Cheek cell being a prokaryote has a primitive form of the body, which shows no membranes around the organelles and the nucleus.
b. Onion cell is a plant cell with a cell wall and a large vacuole. On the other hand, the human cheek cell is an animal cell with a prominent nucleus. Onion cells are brick-like in shape while human cheek cells are rounded. Human cheek cells do not have a cell wall or a large vacuole. Onion cell is an example of plant eukaryotic cell and human cheek cell is an example of an animal eukaryotic cell.

So, the correct answer is option (B) False.

Note:
The onion peel cells are protecting the fruit from any harm and the human cheek cells lack vacuole. Bacteria occur in all shapes and sizes. They are mostly unicellular.
