In tissue culture medium, the embryoids formed from pollen grains is due to
Correct answer: A. Cellular totipotency
- A. Cellular totipotency
- B. organogenesis
- C. Double fertilization
- D. Test tube culture.
Explanation
Totipotency refers to the capacity of each living cell of a multicellular organism being capable of independent development when provided with suitable conditions. Guha and Maheshwari (1966) cultured anthers of Datura. The haploid pollen grain inside the anther divides to form a multicellular mass of cells called callus. Using varying quantities of auxins and cytokinins in the culture medium, this callus is differentiated into embryoids which later germinates to form the entire plant.
