Reproduction of fungi

Sexual and asexual reproduction of the fungi is commonly via spores, often created on specialized structures or in fruiting bodies. Some species have lost the ability to form specialized reproductive structures, and thus proliferate solely by vegetative growth.

Fungi can reproduce either sexually or asexually, depending on conditions in the environment; where certain conditions trigger genetically determined developmental programs leading to the specialized structures for sexual or asexual reproduction, where they can be applicable both reproduction and efficient dissemination of spores or spore-containing propagules.

Asexual

Asexual reproduction via vegetative spores via mycelial fragmentation is common in many fungal species and permits faster dispersal than sexual reproduction. Asexual spores may form a population from the origin, and thus resulting in new colonizing.

Modes of asexual reproduction

Sexual

There are 4 types of fungi reproductive structure for sexual reproduction. They are motile gametes, gametangia, non-motile spermatia fusing with the structure of the female sex organ and compatible vegatative haphae. Fusion of matile gametes brings sexuality which forms the zygote later on. Fusion of gametangia brings about the formation of a zygospore. Spermatization is the transfer of the sperm in this case called the spermatium to a female sex organ. There is also a process called somatogamy which occurs in mushrooms, this is the pocess of the vegetative hyphae fusing.

Modes of sexual reproduction

Nonsexual

There is a few ways for fungi to reproduce for example the most common is by spores. Sporangiospores are spores that are formed in a sac-like structure it contains a lot of them in it and the sac itself is called a sporangium. There is a difference between the spores of aquatic fungi and land fungi, aquatic fungi’s spores are motile and land fungi’s spores are non motile (mostly dispersed by wind). There is another type of reproduction method it is by conidia. It is produced by chain and specialized hyphae which is called conidiophores and are generally dispersed by the wind.
