Groups• 1s- pg 30-31

Compare and contrast multi-cellular and uni-cellular.• 2s- pg 32-33

How were cells discovered and explain the cell theory.

• 3s pg 34-35Compare and contrast the major differences between plant and animal cells.

What feature typically makes plant cells boxy looking?

• 4s Pg 38-39Explain how multi-cellular organisms grow. Why can a cell only get so large???

Jobs of cells

• Even though they are tiny, each cell has everything it needs to survive and reproduce

• Each part of the cell has a special job to do!

DNA

Nucleus

Cell Theory1.All living things are made of

one or more cells.

2.Cells are the basic unit of living things.

3.All cells come from existing cells.

UnicellularONLY 1 cell that performs all jobs necessary to sustain the life of the cell

Multi-CellularHas 2 or more cells that have specialized jobs

2 Types of cells

Plant Animal

Page 8: CELLS. Groups 1s- pg 30-31 Compare and contrast multi-cellular and uni-cellular. 2s- pg 32-33 How were cells discovered and explain the cell theory. 3s.

Animal cellAnimal cells are eukaryotes (have a nucleus)

Do NOT have a cell wall or chloroplast

Millions of different types

Can’t make their own food

Page 9: CELLS. Groups 1s- pg 30-31 Compare and contrast multi-cellular and uni-cellular. 2s- pg 32-33 How were cells discovered and explain the cell theory. 3s.

Have chloroplast and a cell wall

Plant cells are eukaryotes (have nucleus)

Plant cells make there own food through photosynthesis

Plant Cell

Growing…• As multi-cellular

organisms grow, the cells increase in number!

• Chromosomes have all the information to divide

Why so small????To stay a live,

cellsMust take in

oxygenAbsorb foodRelease waste

Big Cell =1. Need more food!

2. Too big to get rid of waste in time!

3. Big Pop! It’s not comin’ back!
