The Life Cycle of a Mushroom

The Life Cycle of a Mushroom A mushroom cloud is a member of a group of fungi called the Basidiomycota. lets consider its life story cycle, beginning with the spores that are produced by the get on harvest-feasting body. The spores are haploid. A spore germinates, dividing by mitosis to produce a filament called a hypha. The hypha festers and branches to produce a filamentous communicate called a mycelium. The mycelium has a high surface-area-to-volume ratio, which allows the fungus to line nutrients efficiently. If the hyphae of different labor union types meet, they are attracted to each other(a) and fuse, forming a carrell with a nucleus from each haploid fungus. A cell with twain different nuclei is called a heterokaryotic cell. The nuclei do not fuse, so the cell is designated n + n. A heterokaryotic mycelium forms. The mycelium continues to grow until the right environmental conditions activate it to grow into a tightly packed, aboveground mass. Th e mature fruit body, or mushroom, also consists of hyphae with dickens nuclei per cell. Each nucleus is calm down haploid. The mushroom has a cap, in which the spores of the next generation are born.

The spores arise on structures called gills on the underside of the cap. The gills consist of hyphae and cells called basidia. The basidia are heterokaryotic, containing two nuclei each, whizz from each mating type. The two haploid nuclei in a basidium fuse to make a diploid nucleus in preparation for meiosis. The diploid nucleus so undergoes meiosis, producing four haploid nuclei. The basidium produces four spores on top of ce llular extensions. The nuclei move into thes! e spores. The haploid spores eventually break off from the basidium, and the life cycle repeats.If you requirement to get a full essay, gild it on our website: BestEssayCheap.com
