1. Do Now:
Draw a picture of a cell and label as many parts as you can.

2. The Cell The parts of a cell are called? Organelles.
Organelles means “little organs”

3. Types of Cells
Plant cell Animal cell

4. The Cell Membrane Surrounds the cell
Allows materials to move in and out
The Cell Membrane (1min 1sec).asf

5. Chromosomes
Made of DNA
Instructions for building the body

6. Nucleus Contains the Chromosomes Found in the center of the cell
Organelles - The Nucleus (1min 6sec).asf

7. Nuclear Membrane
Separates Chromosomes from the rest of the cell.

8. Cytoplasm Supports the Organelles.
Many chemical reactions happen here.
The Cytoplasm (21sec).asf

9. Just like complex organisms, cells are able to survive by coordinating various activities. Complex organisms have a variety of systems, and cells have a variety of organelles that work to help the cell survive. Describe the role of two organelles. In your answer be sure to include:
The names of two organelles and the function of each.
An explanation of how the organelle does it’s job.
The name of the organelle and the name of a part of the human body that has a similar function.

10. Mitochondria Site of cellular respiration (production of ATP)
Powerhouse of the cell
Organelles - Mitochondria.asf

11. Ribosomes
Site of protein synthesis (use information from DNA to make proteins)
Very tiny

12. Endoplasmic Reticulum
Transports materials around the cell
Network of passageways
Organelles - The Endoplasmic Reticulum (33sec).asf

13. Golgi Body
Packages materials for export out of the cell

14. Lysosomes
Contains enzymes that digest foreign particles and old cell parts

15. Storage space for food, water or waste products.
Vacuole
Storage space for food, water or waste products.
Vacuole

16. Write down a part of the cell we learned today that you think is most important and describe why you think it is most important.
Ask a neighbor what they thought was most important and why.
Pick ONE.
Why did you decide to pick that one?

17. Cell Parts (organelles)
There are two types of cells that we are going to be talking about.
Animals are made up of what type of cell?
Answer: Animal cells! (includes humans).
Plants are made up of what type of cell?
Answer: Plant cells!

18. Animal Cell

19. Centrioles
Cylindrical structures only found in animal cells that aid in replication (cell division).

20. Centrioles and Spindle Fibers
Centrioles are anchor point for spindle fibers
Spindle fibers appear during cell division

21. Parts of the Plant Cell
Plants have organelles in them that Animal cells don’t have.

22. Cell Wall
Rigid structure that encloses, supports and protects the cells of plants, algae, fungi and most bacteria.
Cell walls in plants are made of cellulose.

23. Cell Wall
Protective outer layer on plant cells
Adds support

24. Chloroplasts Structures found only in the plant cell.
Site of photosynthesis.
Photo = Light, Synthesis = To make.
So Photosynthesis means to make something (glucose) using Light!

25. Chloroplast Contain Chlorophyll Site of Photosynthesis
