write a note on asexual reproduction of fungi
Answers
Explanation:
How do fungi reproduce? Sexually or asexually?
How about both? That would suggest that fungi can produce both diploid and haploid cells, which they can. Shown above are fungi mycelia and haploid spores. Spores allow fungi to reproduce during unfavorable conditions.
Reproduction of Fungi
Most fungi are able to reproduce both sexually and asexually. Most fungi are haploid for the majority of their lifecycle. This is unlike other eukaryotes; for example, humans spend the majority of their lives as diploid organisms.
Asexual Reproduction
Fungi reproduce asexually by producing genetically identical spores or by breaking off pieces of mycelia. A spore is a reproductive cell made by fungi and other organisms. Spores can grow into an individual without being fertilized. Asexual reproduction is common in many fungal species, and it allows for more rapid spreading of the fungus than sexual reproduction does.
There is great variety of asexual reproductive structures. These structures can be used to identify certain fungi. Some fungi produce spores within a protective sac called a sporangium, while others produce spores that are not surrounded by a protective sac. In some cases, sporogenesis, or the creation of spores, occurs by mitosis. Other fungi produce spores by mitosis and meiosis.
Sporogenesis begins with the growth of special reproductive hyphae called sporangiophores. At the end of a sporangiophore is a structure called a sporangium (plural, sporangia), shown in Figure below. Spores are produced by the mitotic division of haploid spore mother cells within the sporangium.
