LIFE SCIENCE

Detailed explanation-1: -The growth of plants occurs by cell division and cell enlargement. The cell enlarges its size before it undergoes division. Plants increase in mass and number is the characteristic of growth. Multicellular organisms grow by cell division.

Detailed explanation-2: -Cell growth refers to the increase in cell size (mass accumulation) while cell division describes the division of a mother cell into two daughter cells (1->2->4->8, etc.). Cell proliferation is the process of generating an increased number of cells through cell division.

Detailed explanation-3: -For both plants and animals to grow, their cells must divide to produce more cells. In the process of cell division, one cell becomes two.
