What cell division occurs in sporangium?

Answer 1

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.

Answer 2

Meiosis. This will begin the haploid stage as the gametophyte.

Answer 3

During spermatogenesis a cell division called meiosis occurs. This process produces four sperm cells.
