Kingdoms & Key Features
• ARCHAEBACTERIA – first form of life on earth, can live in extreme environments, prokaryotes
• EUBACTERIA – prokaryotes, some help us and some hurt us
• PROTISTA – “junk drawer” kingdom, all eukaryotes, some multicellular and some unicellular, autotrophs or heterotrophs, some stationary, some move
• FUNGI – feed on dead/decaying things, have a nucleus, multicellular (except yeast), not able to move, reproduce by spores
• PLANTAE – autotrophs, multicellular, have cell walls
• ANIMALIA – heterotrophs, multicellular, move at some point in their lives, vertebrates & invertebrates

Bacterial Reproduction
• Two types:
Binary fission – asexual reproduction,
chromosome replicates, then separates
Conjugation – sexual reproduction, cells
attach and exchange info

Virus Function & Replication
• Host cell – cell where the virus replicates
• Why are viruses non-living?
• No organelles
• Can’t reproduce on their own
• Can’t make proteins
• Retrovirus – has RNA instead of DNA
• Lytic Cycle – immediate effects, results in immediate bursting of the host cell, ex: influenza, common cold
• Lysogenic Cycle – long-term effects, becomes part of the cell’s nucleus, can be dormant for years, ex: AIDS, herpes
