Microsporogenesis and megasporogenesis differ in the following ways:
|The process by which
microspore mother cells
divide and produce pollen
grains is known as
|Megasporogenesis is the process
by which megaspore mother cells
are formed and differentiate into
megaspores by meiosis.
|Located within the pollen sac
of the anthers.
|It is present in the nucellus of the
|A pollen grain produced by a
microspore mother cell
|The megaspores have only one
|Results in the formation of
pollen grains (male gametophyte)
|Resulting in the formation of
embryo sacs (female
|Microspore mother cells and
megaspore mother cells are
every diploid, as they have
two sets of chromosomes
|The mother cells for megaspores
and microspores enlarge and
undergo meiosis in order to
produce four haplotypical cells
called megaspores and
