The Kingdoms Of Life
Bacteria :tada: (Monera)
-
Reproduction
-
mutations may occur frequently in bacteria due to their short life cycle and fast rate of reproduction
Endospores
resistant, thick walled spores formed within cell under adverse conditions
-
-
3 types of hyphae
Rhyzoid
- anchors the rhizopus 2. releases enzymes onto bread 3. absorbs broken down nutrients
-
-
sexual reproduction
2 different strains, structurally identical but chemically different
-
-
-
-
Viruses

Viral Replication
-
-
1 - Virus lands on surface of host cell (transferred from air, water, and food, direct contact)
2 - Attachment: virus needs specific proteins to adhere to host. Specific receptors on glycoproteins receptors of the host, virus specifically matches its receptors to host surface and absorbs cell walls.
3 -
4 Uncoats: by some method, nucleic acid must be released from capsid the protein shell (translocation)
-
steps 6 - 10
Biochemical replication-viral genome takes over host and causes it to make viral specific proteins and genome, protein synthesis
-
-
-
Release-lysogeny-virus buds off, host lives lysis-virus bursts cells open, host dies
-
vessicle forms around virus-->virus incased by host membrane vacuole-->lysosome digest membrane-->virus released (w/ w.out capsid)
-
for virus with envelope from previous host: fusion of phospholipid membranes of virus on host cell-->deposit viral genome. membrane will not be broken
-
(for non-enveloped from previous host) virus attach to host cell surface and release lysosome from previous host-->lysosome breaks down cell wall/membrane-->nucleic acid core released without host. capsid is not going in
