CELLS!. 10/18/2010. What are cells?. Robert Hooke in 1665 first called the tiny chambers he saw in a microscope cells . All living things are made out of cells! Cells contain living matter. CELLS MAKE UP EVERY LIVING THING! Plants are made of CELLS! Animals are made of CELLS!
(you, me, plants, bugs, fish, Spiderman, Colonel Sanders, Jimmy Neutron, Bacteria, Yeast, Jackie Chan)
(what keeps us upright and helps us live, basically small workers responsible for how we function!)
(they can’t just appear out of thin air…cells make new cells by dividing!)
All life is classified into three Domains…
Each domain is divided into Kingdoms. There are six different kingdoms…
It’s important to note that both Eubacteria and Archaebacteria are Prokaryotes. All Prokaryotes are single-celled and include all types of bacteria. Eubacteria and Archaebacteria are much more genetically varied than Protists, Plants, Fungus, and Animals, which is why bacteria are divided into two kingdoms.
Let’s look at some examples of organisms in each kingdom…
Bacteria we see everyday. Like streptococci (causes strep throat).
Bacteria found in extreme environments such as hot boiling water and thermal vents with no oxygen or highly acid environments.
Unicellular Eukaryotes: Algae and slime molds. Odds and ends animals (complex but are unicellular)
Flowering plants, mosses, and ferns
Mushrooms, mold, mildew. CANNOT make their own food
Consist of complex cells, are all heterotrophs. Things like tigers, bears, penguins, humans, etc.
