Biology: mitosporagium vs zygosporangium, part 1
Tutoring biology, terms come up. The tutor mentions two connected with reproduction in fungi.
In some fungi, both asexual and sexual reproduction can happen.
Asexual reproduction can be done by undergoing mitosis to produce spores which will be released into the environment, hopefully landing in a welcoming place for development. Those spores will be produced in a mitosporangium, linking with the fact that they are produced by mitosis.
In the case of sexual reproduction, a zygosporangium will result from a meeting of two hyphae of opposite “genders” (which are referred to as + and – rather than male and female in this context). Within the zygosporangium, gametes from each hyphae will fuse with ones from the other to form zygotes. Next, meiosis will take place to produce spores.
In either case, the spores are haploid. Yet, from asexual reproduction they are clones of the parent cells, whereas from sexual reproduction they are a new combination of traits from the two parents.
