1. Domains and Kingdoms of Life

2. 3 Domains Archaea = Prokaryotes Bacteria = Prokaryotes
Eukarya = Eukaryotes (hence the name)
These used to be called one single domain called “Monera”

3. Archaea Prokaryotes These have a very unique and tough cell wall
Halobacteria is tough and highly resistant to hot environments. This hot Sulphur spring is a good environment for these to be found.
Prokaryotes
These have a very unique and tough cell wall
They can be found in very extreme environments
Unique rRNA

4. Bacteria Prokaryotes Cell walls contain peptidoglycan
Sensitive to antibiotics (some exceptions)
Have their own unique rRNA

5. Eukarya May have a cell wall, but it doesn’t have peptidoglycan
Have their own unique rRNA
Resist traditional antibiotics
Remember all that stuff about eukaryotes? All that still applies…

6. 6 Kingdoms Domain Archaea has one kingdom called Archaea (easy)
Domain Bacteria has one kingdom called Bacteria (still easy!)
Domain Eukarya has 4 kingdoms called
Animalia = animals
Plantae = plants
Fungi = fungus
Protista = protists

7. Animals
Always multicellular – meaning they are very complex arrangements of many cells
Heterotrophs – they have to eat sources from other living things for energy
Do not have a cell wall – makes them more motile/moveable
Embryos develop using a blastula – a hollow sphere of cells with fluid while developing early in life.

8. Plants
Multicellular
Autotrophs – they obtain their energy from non-organic sources and produce their own food
Their cell walls are made of cellulose
They contain chloroplasts that photosynthesize
Alternate generations – this means they cycle different genetic features over time so they can have some variation

9. Fungi Mostly multicellular (ex: yeast is single- celled)
Mostly heterotrophs (ex: saprophytes are autotrophs)
Cell walls are made of chitin – gives the exterior a rubbery feel
Reproduce sexually or asexually through spores
Mostly immobile

10. Protists (anything that isn’t a plant or animal)
Mostly microscopic
Mostly single-celled
Some are heterotrophs, some are autotrophs
Reproduce both sexually and asexually
Examples of protists: seaweed (kelp), algae, amoebas, parmeciums.
Protists are pretty much the junk group of all the kingdoms
