Assertion [A]: In the case of unicellular organisms, reproduction is synonymous to growth.
Reason [R]: Growth in unicellular organisms refers to an increase in the number of cells.

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true and R is false
• D. A is false and R is true

Answer 1

The correct option is A Both A and R are true and R is the correct explanation of A

In unicellular organisms such as bacteria and amoeba, growth refers to an increase in population size, and not the size of individual cells (as the latter is not very significantly observable). Reproduction too results in an increase in population size. Growth and reproduction can thus, be said to mean the same in this context.
