Answer 1

The correct option is C In plants and animals, growth occurs continuously throughout their life span

Growth can be defined as the increase in mass and increase in number of cells in an organism. All living organisms show growth. Unicellular organisms grow by cell enlargement as well as by cell division. Multicellular organisms grow by cell division.

In plants, the growth by cell division occurs continuously throughout their life span. But, in animals, growth is seen only up to a certain age. However, cell division occurs in certain tissues to replace lost cells.
