Reproduction

reproductiveprocreationreproduce
The term is also used to refer to the process of reproduction via spores.
Other ways of asexual reproduction include parthenogenesis, fragmentation and spore formation that involves only mitosis.

Diaspore (botany)

diasporediasporesdisseminule
Plant spores designed for dispersal are also referred to as diaspores.

Ovule

ovulesperispermembryo sac
Megasporogenesis occurs in megastrobili in conifers (for example a pine cone) and inside the ovule in the flowers of flowering plants.
In immature ovules, the nucellus contains a megasporocyte (megaspore mother cell), which undergoes sporogenesis via meiosis.

Sporeling

sporelings
Reproductive spores grow into multicellular haploid individuals or sporelings.

Sporangium

sporangiamegasporangiumsporangiospore
Sporogenesis occurs in reproductive structures termed sporangia.

Isogamy

conjugationisogamousSexual conjugation
The zygospore forms through the isogamic fusion of two cells (motile single cells in Chlamydomonas) or sexual conjugation between two hyphae (in zygomycota).
In many cases, isogamous fertilization is used by organisms that can also reproduce asexually through binary fission, budding, or asexual spore formation.

Mitotic sporogenesis is a form of asexual reproduction.

Aspergillus

Examples are the conidial fungi Aspergillus and Penicillium, for which mitospore formation appears to be the primary mode of reproduction.

Other fungi, such as ascomycetes, utilize both mitotic and meiotic spores.

Polysiphonia

The red alga Polysiphonia alternates between mitotic and meiotic sporogenesis and both processes are required to complete its complex reproductive life cycle.

Fertilisation
