Useful information on the diffused, multiplicative and localized cell growth in plants

ADVERTISEMENTS:

Basically growth can be of three types. They are diffused, multiplicative and localized cell growth in plants.

1. Diffused growth:

In unicellular organisms growth means an increase in the synthesis of materials, proliferation in the number of cellular organelles and an expansion in cell size. Cell division is responsible for an increase in their population. This type of growth is known as diffused growth as seen in algae, fungi, bacteria, etc.

2. Multiplicative Growth:

In multicellular organisms, by the process of meiosis, male and female gametes arte formed which unite to form zygote. Zygote divides by repeated mitotic division. The number of cells increases but the cell size gets smaller. This type of growth is known as multiplicative growth.

3. Localized Growth:

ADVERTISEMENTS:

In this type growth is restricted to certain fixed regions like root tips and shoot tips.
