Agenda: The Big Idea: Warm-Up(Level 0) Students recognize Notes on Cells (Level 1) that the presence of a nucleus determines whether a cell is prokaryotic or eukaryotic. (6. 12 B) Developed by Jackson MS 6 th grade

Warm-Up What is the difference between an organism that is unicellular and one that is multi-cellular? “One difference between unicellular and multicellular is… unicellular is one cell and multi-cellular has many cells.

Prokaryote and Eukaryote “Pro” is a Greek prefix that means before. Karyose is a Greek word that means kernel like in corn not like in Sanders. So Prokaryote means cells BEFORE OR WITHOUT A NUCLEUS. Ex. Bacteria “Eu” is a Greek prefix that means true or good. So Eukaryote means a cell WITH A TRUE NUCLEUS. Ex. All animal cells, plants, protists, and fungi.

Prokaryote and Unicellular Description: Simple Structure No Nucleus No Membrane bound organelles. Earliest known organisms (3. 5 billion yrs. ) Microscopic Examples: All forms of bacteria and archaebacteria like E. coli, salmonella, staphylococcus,

Eukaryote and Multi Cellular Description: Very Complex Structure Well defined nucleus Many organelles Organisms you’re more familiar with because you see them all the time. Examples: Animals, Plants, Fungi (mushrooms) Some Protists (Algae)
