Consider the following two statements:
I. In the single-celled organisms, we are not very clear about the usage of the two terms – growth and reproduction.
II. When it comes to unicellular organisms like bacteria, unicellular algae or amoeba, reproduction is synonymous with growth, i.e., increase in number of cells.
1. Both I and II are true and II explains I
2. Both I and II are true but II does not explain I
3. I is true but II is false
4. Both I and II are false
In single-celled organisms, growth and reproduction are often used interchangeably, and the increase in the number of cells is a direct result of reproduction.Prefer Books for Question Practice? Get NEETprep's Unique MCQ Books with Online Audio/Video/Text Solutions via Telegram Bot
