microspore -- In plants which are heterosporous, the smaller kind of spore is called a microspore; it usually germinates into a male (sperm-producing) gametophyte. Contrast with megaspore.
Microspore- A haploid spore produced by meiosis of the microsporocyte and developing into the male gametophyte. The pollen grain of seed plants.
Mine spoil- Earth and rock excavated from a mine.
POLLEN: The microspores that carry the male gametophyte of seed plants.
POLLINATOR: Any being, insect or creature such as bees, moths, butterflies, animals and insects that move from plant to plant.
Pollen: the mass of microspores in a seed plant that usually appears as a fine dust and is the agent of .
Pollination: the transfer of pollen from the male part of a flower (stamen) to the female part of a flower (the and ).
Pollen The male cells or microspores produced by the stamens.
Pollination The transfer of pollen from the stamen (male part of the flower) to the pistil (female part of the flower), which results in the formation of a seed.
Each pollen sac, or microsporangium, of the anther contains numberous microsporocytes, each of which undergoes meiosis to form four haploid microspores. Every microspore develops into an immature male gametophyte, also called a pollen grain.
Pollen - fine, yellow, dust-like microspores containing male genes.
Pod seed - a dry calyx containing a mature or maturing seed.
