Plant growth is
A
dry weather
B
size increase by cell division and enlargement
C
size increase by vegetative state
D
seed germination
Explanation: 

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: -The final shape of a growing plant cell, and hence the final form of the plant, is determined by controlled cell expansion. Expansion occurs in response to turgor pressure in a direction that depends in part on the arrangement of the cellulose microfibrils in the wall.

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. This process is different in plant and animal cells because plant cells have cell walls.

Detailed explanation-4: -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.
