|
Fungi |
* Made of hyphae filaments
* cell wall made of chitin * hetertrophs * ex: yeast, molds, mushrooms, etc. |
|
|
haustoria |
parasitic hyphae |
|
|
lichens |
fungi + algae |
|
|
Mycorrhizae |
fungi + plant roots |
|
|
fungi reproduction |
* sexual or asexual
* via spores or mycelial fragmentation * have both haploid and diploid stages |
|
|
Virus structure |
1. nucleic acid: DNA or RNA 2. protein coat 3. envelope (bud of host membrane) or no envelope (causes lysis) |
|
|
virus vs bacteria |
* smaller than bacteria
|
|
|
retrovirus |
convert their genome into DNA inside their host |
|
|
virus life cycle |
* can't replicate on their own
* attachment --> penetration --> use host resources to replicate genetic info --> self-assembly --> release |
|
|
bacteria structure |
1. no nuclear membrane 2. no spindles/asters 3. no Golgi, ER, mitochondria or chloroplasts 4. shape: bacilli, spirilli, cocci, eubacteria, archaea 5. peptidoglycan cell wall 6. flagellar propulsion |
|
|
bacterial transformation vs transduction |
transformation: bacteria integrate plasmids and DNA fragments into the genome
transduction: bacteriophages incorporate the viral DNA into the bacterial genome |
|
|
bacterial reproduction |
1. via fission 2. conjugation can occur via sex pillus |
|
|
Obligate anaerobe |
dies when oxygen is present |
|
|
Facultative anaerobe |
doesn't need oxygen for growth, but grows better with oxygen |
