Pollen grains are the carrier of male gametes in

Sometimes more than 4 pollen grains are produced from one microspore mother cell, it is called

The tissue that nourishes the developing pollen grain is:

To produce 500 pollen grains, how many microspore mother cells are required ?

A mature male gametophyte is formed from pollen mother cell by

The cells of sporogenous tissue undergo____ division to form microspore tetrads.

Read the following statements and find out the incorrect statements. a. In majority of organisms, male gamete is motile and female gamete is non-motile (stationary). b. In algae and fingi, both male and femla egaetes are non-motile. c. In seed plants, pollen grains are the carrier of male gaemtes and ovule has the egg. d. In dioecious plants, pollination facilitates trasnfer of pollen grains to the stigma. e. In monoecious animals, since male and female gametes are formed in different individuals, the organism must evolve special mechanism for gamete transfer.
