Characteristics of living things - Are made of more than one cell
- Hierarchical Organization (organelles biosphere
- Reproduces
- Grows and develops
- Obtain and uses energy
- Responds to their environment
What is evolution 1. The process in which species change
2. Any change in the frequency of an allele in a population's gene pool
3. Property of a population not an individual
Darwin's theory of evolution - high reproductive rate
- constant population

Archaea - cell membrane made of lipids
- glycerol-hydrocarbon units linked together by ether bonds (R-O-R)
- Maintains membrane integrity in extreme conditions
Bacteria - glycerol-fatty acid units linked together by ester bonds (O=C-O-R)
- Most common type of bacteria
Eukarya - phospholipid bilayer - imbedded with sterols
- Have a nucleus and membrane bound organelles
- Changing- new kingdoms and candidate kingdoms are being created and merged
What structure does Fungi have? Hyphae Mycelium Structure
What is Hyphae long thin fibers that come together and create Mycelium
Septate Hyphae has a cept or crosswall
Coenocytic Hyphae has no crosswall
Haustoria Hyphae has a sharp end used for penetration
Prey Hyphae looks like round laso and when the prey gets into the loop the more the prey
struggles to get out the more stuck they get
