Question

In anther culture, the androgenic haploid plants are obtained from
A. Young pollen grain
B. Connective tissue
C. Anther tapetum
D. Anther wall

Answer 1

Hint:-The normal development of the pollen grains leads to the formation of male gamete which on interaction with female gamete leads to the formation of egg which develops to produce the diploid organism.

Complete step-by-step solution:-Another is the male part of the plant body which is sac like structure and produces microspores i.e. pollen grains for the pollination to occur.
Another culture is the process of regeneration of plants from microspores which are haploid in nature to obtain the desired product of haploid and diploid both. The first successful anther culture was done for buckwheat Miyazaki-Zarai and the generation produced was all diploid organisms.
In anther culture the natural habitat and the environment of the anther enclosed is not disturbed, and by using the intact anther the pollen grain can be grown. Anther culture has led to inbred inline development with the fixation of homozygosity.
Connective tissue: They are types of tissue which provide the attachment and support to various types of cells and organs in the body.
Anther tapetum: it forms the innermost layer of another, surrounding the pollen mother cells and provides for microsporogenesis required enzymes and nutrients.
Another wall: It is an outermost layer surrounding another composed of three layers: epidermis, endothecium and tapetum.

Thus the correct option is A.

Note:-
 The importance of anther culture is there as it has its major application:
1. It has its major application in the study of mutations.
2. With the use of another culture, great productivity for haploid plants can be generated.
3. It plays a role in plant breeding.
4. It plays an important role in crop improvement.
