life cycle of rhizopus: asexual reproduction Flashcards
define sporulation
it is the process of making spores
after a few day’s growth, what happens?
some hyphae grow up from the surface of the substrate. these are called sporangiophores
When the tips of sporangiophores swells, what happnes?
They produce a sporangium whos contents divide by mitosis to form numerous spores
What does each spore produced by mitosis have?
Atleast one haploid nucleus
The base of the sporangium is called what?
It is a wall called the columella
What does the columella surround?
It surrounds a swollen area called the apophysis
In dry conditions, what happens to the sporangium?
It dries out and opens to release many spores.
Each spore blows away and grows into a new hypha and mycelium if it lands on a suitable substrate
