GENERAL KNOWLEDGE

Detailed explanation-1: -The male sex organ, Antheridia, is a haploid structure that produces male gametes known as antherozoids or sperms. A sterile jacket surrounds a high number of cubic spermatozoic sperm mother cells in an antheridium. Cryptogams male gametes, also known as sperms, are motile, which means they need water to fertilize.

Detailed explanation-2: -general, the male gametes (antherozoids) are produced in globose structures (antheridia) that are either stalked or sunken in the gametophyte. The antherozoids, always many in number, develop from mother cells enclosed in the jacket of the antheridium.

Detailed explanation-3: -Antherozoids are the male gametes formed in bryophytes. These are borne in the antheridia, which are the male sex organs.

Detailed explanation-4: -Antherozoids are motile male gametes or mature sexual reproductive cells, having a single set of unpaired chromosomes.
