In angiosperms, each microspore mother cell undergoing meiosis gives rise to a ___.

Q. In angiosperms each microspore mother cell undergoing meiosis gives rise to a ___.

Q. Based on the given excerpt, answer the given question.

Stamen is regarded as a microsporophyll that possesses microsporangia which have microspore mother cells that give rise to microspores. The cells of sporogenous tissues undergo meiotic division to form microspore tetrad. Microspore is present in the bilobed structure called anther. A male gametophyte is a gamete producing haploid phase in a plant. In angiosperms, it is the pollen grains that are regarded as gametophytes.

A dithecous anther is __________.
[1 mark]

Q. Assertion :In a microsporangium, the tapetal cells, possess little cytoplasm and generally have a single prominent nucleus. Reason: During microsporangenesis, the microspore mother cells(MMCs) undergo mitotic divisions to produce haploid microspore tetrads.
