Zygomycosis and the Joplin Tornado

Basic Structures

July 2011

Now, these are examples of the structures we just talked about. The sporangia you see on the right of the sac like structures. The curved structure in this particular illustration is the sporangiophore. The sporangiophore supports the sporangium which contains all of those sporangiospores. And a mature sporangia will actually rupture the wall and dissolve and all those spores go out into environment and start to form new structures all over again. The rhizoids we mentioned are the root like structures that are helpful in making this genus identification and you can see that on the lower illustration.
