1 Domains & Kingdoms

2 The Current System What is the largest category? What is alive?
They must have the 8 characteristics of life. Biotic vs. Abiotic Is a virus alive?

3 Life ? What is a virus? DNA with a protein coat.
Does it have the 8 characteristics of life? Lets review.

4 The 8 Characteristics of Life
Does a virus have all 8? Made of Cells Has DNA Needs Energy and Materials Reproduces Grows and Develops Reacts to the Environment Maintains Homeostasis Has Adaptations

5 Domain? All life has cells. Not all cells are the same.

6 What kinds of cells do we know of?
Prokaryotes – no “membrane bound” organelles, very small, bacteria, circular DNA, most abundant on Earth. Eukaryotes – has “membrane bound” organelles (e.g. nucleus, mitochondria, chloroplast), large, unicellular or multicellular, linear DNA Plant (autotrophs) or Animal (heterotrophs) Stop thinking plant or animal for this unit…fungi?

7 The 3 Domains Archaea - Prokaryotes Bacteria - Prokaryotes
Eukarya - Eukaryotes

8 Prokaryotes – 2 Kingdoms 2 Domains
Domain Archaea Archaeabacteria Extremophiles Live in extreme environments. Boiling hot springs, hydrothermal vents, salty lakes. Scientists think these were the first life on earth. Domain Bacteria Eubacteria The largest Domain Most prokaryotes are in this group.

9 Eukaryotes – 4 Kingdoms 1 Domain
Domain Eukarya Animalia - Animals Plantae - Plants Fungi - Fungus Protista - Protists

10 6 Kingdoms (The Current System)
Eukaryote Cells Animalia - heterotrophs (multicellular) Plantae - autotrophs (multicellular) Fungi - heterotrophs (multicellular) Protista - autotrophs & heterotrophs (single celled) Prokaryote Cells Eubacteria - autotrophs & heterotrophs (single celled) Archaeabacteria - autotrophs & heterotrophs (single celled)
