Question

Assertion [A]: Majority of the cells cannot be seen directly with the naked eye.

Reason [R]: All the cells are microscopic in size.

• A. Only A is correct
• B. Only R is correct
• C. Both A and R are correct, and R is the correct explanation for A
• D. Both A and R are correct, but R is not the correct explanation for A

Answer 1

The correct option is A Only A is correct

Most of the cells are microscopic in size. Hence, they are not visible to the naked eye. They need to be enlarged or magnified by a microscope to be seen. E.g., the bacterial cell (0.1 to 0.5 mm). On the other hand there are certain cells, like the egg of a hen, which can be seen with the unaided eye.
