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???

What is a cell?
* The smallest unit that can carry out the activities of life!
* The building blocks of all life!

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

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

Have chloroplast and a cell wall
Plant cells are eukaryotes (have nucleus)
Plant cells make there own food through photosynthesis

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!
