4. Unicellular vs. Multicellular
All living things are made of cells.
UNIcellular Organism
one cell
One cell carries out ALL activities.
What they have in common
Cell is the basic unit
Carry out life functions
Get energy from food
reproduce
3)waste removal
MULTIcellular
Organism
many cells
Different types of cells.
Each cell has its own job to do.
“specialized” or “differentiated”

5. Cell Specialization/Differentiation
Cell Specialization – to become special
Cell Differentiation – to become different
As newly fertilized cell divides from one cell to many, the cells will be assigned a job and become “specialized.”

6. Cell Specialization
Cells in multicellular organisms are “specialized” to do different jobs.
Over 200 different types of cells in the human body.
Type of Cell
Function (Job)
Muscle Cell
Move body parts
Bone Cells
Support and Protect Body
Nerve Cells
Send and Receive Messages
Immune Cells
Fight Disease
Blood Cells
Transport materials to cells

7. What do you notice about all of these human cells?

8. Form and Function The shape of a cell is determined by its job.
Different shapes because they have different jobs.

9. Form and Function Type of Cell Form (Structure) Function (Job)
Nerve CELL

10. Form and Function Type of Cell Form (Structure) Function (Job)
RED BLOOD CELL

11. The BIG Ideas ( STRUCTURE follows FUNCTION )
1) Multicellular organisms have……
many different types of cells.
Which have different jobs.
2) Each cell has a different shape because it has a different job.
( STRUCTURE follows FUNCTION )
