In addition, multi-cellular fungi are classified based on the structure of their mycelium. Only ~ (those with 2 nuclei) mycelium are capable of sexual reproduction while homokaryotic mycelium reproduce asexually. Spores are formed on the mycelium which develop and grow into hyphae. In rust fungi, a cup at the surface of the host in which ~ spores called aeciospores are produced During cell division, formation of the hook ensures proper distribution of the newly divided nuclei into the apical and basal hyphal compartments. In ascomycetes, ~ hyphae of the hymenium (the spore-bearing tissue layer) form a characteristic hook at the hyphal septum.

The chytrids separated from the remaining phyla approximately 550 million years ago, followed by splintering of the Zygomycota from the other two phyla, which share septate hyphae and ~ stages in their life cycles. Having two distinct sets of genetic information. Dikaryosis is a significant genetic peculiarity of the fungi.

It is takes place in fungus, Rhizopus and to produce some flowers and fruits.Ī) The large number of spores will produce in short period of time.Ī) The planaria can be considered as model organ for the process of regeneration.ī) The planaria have ability to release their damaged parts as depicted in diagram.Ĭ) If due to mechanical injury or any cause, the cut in the body can occur.ĭ) Under such conditions, the part of organism can again be regenerated.Dikaryotic: A cell that contains two separate haploid nuclei (n+n) which is different from being haploid (n) or diploid (2n). The sporogenesis is formation of spore for the purpose of reproduction. When the spores will settle, they will germinate and new organism will formed.Ī) The large number of spores will produced in short period of timeī) For the spore formation, less energy will required.Ĭ) Spores will get diffuse or spread on its own they don’t require any route for spread.Īnswer: Spore formation is a type of asexual reproduction. Process of Spore Formation / Sporogenesis:Ī)The spores are basically single celled called particles that are used for formation of new organisms.ī) The spores are released from the sporangia of a particular plant.Ĭ) When the spores are matured, they will start release from sporangium.ĭ) The released spores will diffuse of spread through air, water and insect. It is takes place in fungus, Rhizopus and to produce some flowers and fruits. citation needed Spores form part of the life cycles of many plants, algae, fungi and protozoa.Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable. The sporogenesis is formation of spore for the purpose of reproduction. In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions.

Spore formation is a type of asexual reproduction.
