|
|
what is budding?
|
a form of asexual reproduction where a new organism grows off of a parent organism
|
|
|
what is regeneration?
|
a type of asexual reproduction where a piece breaks off and grows into new hyphae
|
|
|
what is spore production?
|
a type of asexual reprodcuction where spores are reproductive cells that germinate and develop into a new organism
|
|
|
how does sexual reproduction take place in fungi?
|
The hyphae of the two different mating types fuse during sexual reproduction and grow into the distinct reproductive structures called fruiting bodies
|
|
|
are zygomycota Terrestrial decomposers?
|
yes
|
|
|
give an exampl of zygomycota
|
black bread mold
|
|
|
how do zygomycota reproduce asexually?
|
asexually by producing spores in a sporangium
|
|
|
how do zygomycota reproduce sexually?
|
Tips of 2 different mating types fuse in conjugation. The n nuclei form 2n zygotes when fused. The fused gametangia forms a zygospore that contains the 2n zygotes that undergo meiosis to form n spores
