Question

Which of these best shows that plant cells are
totipotent ?
(a) A shoot culture for the purpose of micropro-
pagation
(b) Flower meristem culture for the purpose of
somatic embryos
(c) Protoplasmic culture for the purpose of
genetic engineering of plants
(d) Leaf, stem and root culture for the purpose
of cell suspension cultures

Answer 1

Protoplasmic culture for the purpose of genetic engineering of plants best shows that plant cells are totipotent.  

• Option (c) is correct
• The ability of a cell to give rise to new cells offering maternal support
• OR
• to divide and differentiate into the different type of cells is called totipotency.
• The examples are cambium and callus.

Answer 2

Protoplasmic culture for the purpose of genetic engineering of plants

Explanation:

• The totipotency is defined as a character of a living cell to differentiate into any organ of that organism when necessary.

• In case of humans these are the stem cells that are found in few parts of body, and in intrauterine life.

• In case of plants, each and every living cell is a totipotent cell.

• This is why, cells from any part can be collected and that can be used for plant reproduction.

• The process is called cell culturing.

• Here the living cells are treated with hormones and given true conditions when the cells grow and divide to form a callus or Tumour.

• From this callus, the roots and shoots grow to give rise to a complete plant.
