
Compare and Contrast “water” and a “plant”
How are they the same?
How are they different?
What makes a “water” a “water?”
What makes a “plant” a “plant?”
We will begin class 4 minutes after the bell
Please work the whole 4 minutes!

All living things are composed of cells
Cells are the basic units of structure and
function of living things
New cell are produced from existing cellsreproduction and development
All organisms require energy to carry out
certain processes. (metabolism)
Response to their environment –all
organisms must react to their environment
to survive.

Brainstorm
◦ characteristics these cells have in common
◦ characteristics these cells have different

Classify the cells you see into two or three
groups
◦ Explain what characteristics you used to put each
cell in a particular group
◦ Give a name for each group

Use observations to write a definition of a
“cell”




Genetic material not contained in a nucleus
Smaller
Simpler; less complicated
Examples:
◦ Archaebacteria – extreme environment
◦ Eubacteria – E.coli

Genetic material is contained in a nucleus
◦ Separated from rest of cell



Complex
Larger
Variety
◦ Single-cell organisms – Amoeba
◦ Multi-cell organisms – plants, animals, fungi,
protista
Plant Cell
Prokaryote Cells
No nucleus
