contrasting several microbes

Post by bionewbie » Tue Jan 31, 2006 3:54 am

Hi, I'm just having trouble with the differences between the following:

a) budding yeasts and fission yeasts
b) vegetative and reproductive hyphae
c) fungal colonies and bacterial colonies

Budding - a single individual creates a little process called as bud. It will grow bigger and can as big as its 'mother'

Fission - a single individual divides itself into two pieces with similiar size

Vegetative hyphae - the portion that produces asexual reproductive spores; these include the following:
1. conidiospores: spores borne externally on an aerial hypha called a conidiophore (Penicillium and of Aspergillus)
2. sporangiospores: spores borne in a sac or sporangium on an aerial hypha called a sporangiophore (Rhizopus)
3. arthrospores: spores produced by fragmentation of a vegetative hypha

Reproductive hyphae - the portion that produces sexual reproductive spores such as ascospores and zygospores but this is not common

Fungal colonies
- created by fungal species

Bacterial colonies
- created by bacterial species
