A) microspore mother cells
B) microspores
C) 2- celled pollen grains
D) all of the above.
Correct Answer: B
Solution :
: In nature, pollen mother cells (diploid) give rise to pollen tetrads through meiotic division. These microspores are released in the atmosphere. Plant tissue culture technique for obtaining haploid cultures is simple and efficient. Closed flower buds, which have anthers containing haploid (n) microspores are most suitable for the induction of androgenesis. Excised flower buds are sterilized and cut open longitudinally with the help of scalpel and anthers are transferred on the culture medium.
