1. Looking Inside Cells

2. Cell Wall
Description: strong, stiff layer outside of the cell membrane Function: protects and supports the cell Only in plant cells

3. Cell Membrane
Description: elastic and flexible layer that surrounds the cell – has small openings called pores
Function: controls what goes in and out of the cell - “doorway of the cell”
Found in both

4. Nucleus
Description: circle or oval - surrounded by the nuclear membrane Function:“The Control Center” or “brain” of the cell that holds the DNA and directs all of the cell’s activities Found in both

5. chromosomes
Description: shaped like an “X” - found in the nucleus- made of DNA
Function: passes on traits to the new cell
Found in both

6. Nuclear Membrane
Description: layer that surrounds the nucleus and has pores Function: controls what goes in and out of the nucleus – “doorway of the nucleus” Found in both

7. Nucleolus Description: small, round object in the nucleus
Function: where ribosomes are made
Found in both

8. Cytoplasm Description: clear, thick, gel-like fluid
Function: holds the organelles in place
Found in both

9. Mitochondria
Description: rod or oval shaped with a folded line inside Function: “The Powerhouse” – it produces the energy the cell needs Found in both

10. Endoplasmic Reticulum (ER)
Description: clear tubes that make a maze of passageways Function: carry materials from one place to another -the “transportation system” Found in both

11. Ribosomes
Description: small circles – attached to the ER or floating in the cytoplasm
Function: makes proteins – “factory”
Found in both

12. Golgi Bodies Description: stack of pancakes – flattened tubes
Function: receives, packages, and sends out materials -acts like a “post office”
Found in both

13. Chloroplasts
Description: green ovals (they are green because of chlorophyll) Function: traps energy from the sun to produce food for the plant cell Only in plants

14. Vacuoles
Description: small and round in animal cells and one large oval (foot) in plant cells Function: stores water, food , and wastes - the “storage area” Found in both (but they are different size and shape)

15. Lysosomes Description: small and round
Function: to break down food and destroy old cells - “Clean-up Crew” – garbage disposal
Found in animal cells and rare in plant cells
