What cell division occurs in sporangium?
Sporogenesis occurs in reproductive structures called sporangia.
In this type of reproduction sporogenous cells ( also referred to
as spore mother cells or sporocytes) undergo cell division to give
rise to spores.
In conifers and flowering plants meitoic division occurs in the
sporangium. In this type of cell division a diploid mother cell
within the sporangium undergoes meiosis producing four haploid
spores.
In gymnosperms like conifers microspores are produced through
meiosis of the microsporocytes of the male cones.
In flowering plants the microsporocytes are produced in the
anthers of flowers.
Some fungi and algae produce mitospores in the sporangium
through mitotic cell division.
