1. Essential Questions: What are the structures that make up a cell?
How do cells perform the functions needed for life?
How are cells organized to create the structure of organisms?

2. The cell is the basic structure and function of living things.
Structure- how a part or organism is built
Function- the job, processes, or activities that are done

3. Two kinds of Organisms Multicellular Organisms Unicellular Organisms
Many-celled
More than 1 cell
Examples: Plants, Animals, Fungi
1 celled
Single-celled
Examples: Bacteria, Protists

4. Organisms’ Can ALSO BE…
Prokaryote (Prokaryotic)
Eukaryote (Eukaryotic)
an organism whose cells do NOT have a nucleus.
an organism whose cells have genetic material enclosed in a nucleus.

5. Find the Location and Function of these Organelles
Cell Wall
Cell Membrane
Cytoplasm
Nucleus
Nucleolus
Nuclear Envelope (Membrane)
Chromatin/DNA
Mitochondria
Chloroplast
Ribosome

6. Eukaryotic Cell Organelles
Location and Functions
Organelle- Part of a cell that perform specific functions

7. Cell Membrane
Location: Separates the inside of the cell from the outside environment Function: Acts as a barrier Controls what goes in and out of a cell; semi-permeable

8. Cell Wall
Location: In PLANT CELLS ONLY!! Outside the cell membrane Function: Rigid structure that gives support and protection to the cell

9. Cytoplasm
Location: Inside all cells Function: Gel-like material/liquid that fills the cell and holds organelles

10. Nucleus Location: “middle of the cell” In the cytoplasm Function:
Control center of the cell
Contains the cell’s DNA

11. Nuclear Envelope Nuclear Membrane
Location:
-Surrounds the nucleus
Function:
Acts as a barrier
Controls what goes in and out of the nucleus

12. Nucleolus
Location: Dark spot in nucleus Function: -Where the cell begins to make proteins

13. Chromatin/DNA Location: -In the nucleus of eukaryotes
-In the cytoplasm of prokaryotes
Function:
-set of instructions for the cell
-genetic information that determines organisms’ characteristics

14. Mitochondria Location: In cytoplasm Function:
-Food energy/sugar is broken down to produce energy -“Powerhouse of the Cell”
-Cellular Respiration- food energy is broken down and stored as ATP and can be released to do work

15. Chloroplasts
Location: In PLANT cells only; in the cytoplasm Function: Captures energy from sunlight and uses it to make food (sugar) for the cell. Performs photosynthesis Filled with “Green” chemical- chlorophyll

16. Ribosomes
Location: On the ER or in Cytoplasm Smallest and most plentiful organelle Function: Makes proteins

17. Exit Slip
How did the cell theory help scientists or humans “See the world with new eyes”?
What is the difference between prokaryotes and eukaryotes?
Name 3 structures in the cell and explain their functions.
Why is the cell considered the basic structure and function of living things?

18. Endoplasmic Reticulum
Location: In cytoplasm; usually close to the nucleus Function: Passage ways that carry proteins and materials through the cell

19. Golgi Bodies Golgi Complex, Golgi Apparatus
Location: In cytoplasm Function: -Processes, packages, and transports materials out of the cell

20. Vesicle
Location: In ER ,Golgi, or cytoplasm Can be outside of the cell too Function: small sac that contains materials to be moved in or out of the cell.

21. Lysosome
Location: -Cytoplasm of cells Function: -Breaks down waste, food particles, worn-out cell parts, or foreign invaders -clean-up crew

22. Vacuole Location: -In the Cytoplasm
** Especially large in plant cells.**
-May not be in animal cells
Function:
-Stores water or other materials

24. Cytoskeleton
Location: cytoplasm Function: Web of proteins that acts a muscle and skeleton Helps movement Keeps Membrane from collapsing.
