Introduction:

The word totipotency (totipotentia in Latin) means ability for all. Totipotency in biology is a unique characteristic of plants and animal cells. The application of this special characteristic is widely used in tissue culture techniques to grow a large number of cells in a controlled environment. Cellular totipotency is important for studying the fundamental and applied aspects of plant biology.

Explanation

The word totipotency is defined as the genetic ability of a plant to form an entire plant from a single cell in a sterile environment. The cell may be obtained from the root, stem, and other parts of plant. The culture medium provides minerals, nutrients, hormones, and vitamins to promote cell growth and cell division.
