It depends on whether you are talking about animals or plants. In plants it is a pollen grain (microgametophyte) and in animals is a sperm (spermatozoa)
it is the sex cell of the male gametophyte.......

Spermatozoa

Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
Pollen Grains
The gametophytes of gymnosperms live inside reproductive structures called cones. Gametophyte is the immediate result of fertilization in mosses.
They are generated from cells that underwent meiosis.
. The male reproductive organ in an angiosperm is called the stamen. It contains pollen which houses the gametophytes (sperm) and are found in sacks called anthers.
Male and Female gametophytes are in separate plants
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
Pollen Grains
The gametophyte will not fertilize its own egg.This increase the chance of offsprings will have new combination of genes
Where are the male gametophytes produced in Figure 22-4?(1 point)(0 pts) A(1 pt) B(0 pts) C(0 pts) D
in bryophytes the sporophytes is diploid(2n) while the gametophyte in bryophytes is haploid(n).In bryophytes the sporophytes are totally or partially dependent on gametophytes while gametophytes are the dominant generation in bryophytes.Male sporophytes produce male spores and that of female produce megaspores of female spores while male gametophytes produce male gametes while female gametophytes produce female gametes
In flowering plants, megaspores become the female gametophytes.
Depends if you are talking about animals or plants. Plants: male gametophytes (pollen grains) are found in the anther(microsprangium), female ovules are found in the ovary (megasporangium). Animals: Generally male found in the testes and female gametophyes in the ovaries

Stamen produce microspores which create pollen grains that contain male gametophytes.
