2. Plant Cell A B C D E H F G

3. Animal Cell I J H A G B C F D E

4. Cell Membrane Both plant and animal cells Description Function
Inside cell wall of plant
Outer layer for animal
Selectively permeable
Function
Support and protection
Controls what enters and leaves the cell
Maintain homeostasis
Barrier between cell and outside environment

5. Cell Wall Only found in plant cells Description Functions Outer layer
Rigid, strong stiff
Made of cellulose.
Functions
Support and protection
Allows water, oxygen, and carbon dioxide in and out of cell.

6. The Nucleus Both plant and animal Description Function
Large oval structure
Function
Controls most activities in the cell
Contains all genetic information in the form of DNA.

7. Cytoplasm Both plant and animal Description Function
Clear, thick, jellylike fluid within cell that contains all organelles
Inside cell membrane
Function
Allows movement of materials throughout the cell
Supports and protects organelles

8. Endoplasmic Reticulum
Both plant and animal
Description
Series of folded membranes that form sacs or tubes
Function
carries materials through cell
lipid components of cell membrane are assembled.
modify proteins made by ribosomes
Rough ER has ribosomes attached

9. Ribosomes Both animal and plant Also in prokaryotes! Description
Small bodies, free or attached to ER
Function
Makes proteins in the cell
May be free in cytoplasm or attached to ER
Proteins are vital to life- all cells must produce them

10. Golgi Bodies Both plant and animal Description Function
Saclike, folded membranes
Function
modifies, sorts, and packages proteins
prepares cell components for storage or movement out of cell
Cells that make saliva or mucus have many Golgi bodies

11. Mitochondria Both plant and animal Description Function
bean-shaped with inner membranes
Function
breaks down sugar molecules into energy
Energy producers
Powerhouse of the cell
Many mitochondria in muscle cells

12. Chloroplast Only plant cells Description
Green, oval usually containing chlorophyll
Double membrane
Function
uses energy from sun to make food for the plant (photosynthesis)

13. Vacuoles Plants have few that are large Animals have small vacuoles
Description
Fluid filled sacs
Function
Store food, water, or waste materials
In plants the pressure adds support for heavy leaves
Plant need to store lots of food!
Vacuoles

14. Lysosomes Plant –uncommon Animals - common Description
Small, round with a membrane
Function
Contain digestive enzymes to digest unwanted particles
Digests old cell parts
Help white blood cells to destroy bacteria

22. Summarize: What did you notice about all of the plant cells?
What did you notice about all of the animal cells?

23. Cell Specialization: Benefit of Multicellular Organisms
How are the plant cells that are found in the leaves of a tree different from the plant cells that are found in the roots of the tree?
How are our skin cells different from our muscle cells?
