1. Cell Specialization (1.1)
What does it mean to be specialized?

2. Cell Specialization (3.01)
Observations
Function
Name
Location in the organism.
Ex. 1 2 3 4 5 6
Special

3. When you see each cell type, DO NOT name it (even if you know)
Write observations about the STRUCTURE.
Start with the example:

11. Functions- Start with the EXAMPLE
Functions- Start with the EXAMPLE. Does the structure match the function?

12. Match the following functions with each cell type based on their structure. Write the underlined portion.
Carry impulses from the brain all over the body.
Support and movement. Rigid. Strong due to layers. Offer protection for more delicate organs.
Carry oxygen to organs through blood vessels.
Used for movement. Created to flex and stretch over surfaces and to move bone. Contain LOTS of mitochondria for energy.
Store excess water and pump it out to prevent single celled organisms from exploding.
Move through blood vessels to seek out infection and invaders. They recognize them and destroy them.

13. Re-create: Cell # Observations Function Name Location in the organism.
Ex.
Tail
Moving DNA to egg
Sperm Cell
testis 1
Used for Movement
Muscle Cells 2
Carry Oxygen
Red Blood Cells 3
Carry Impulses
Nerve Cells (neurons) 4
Seek out infection and invaders
White Blood Cell (immunity) 5
Support and Movement
Bone Cell (osteocyte) 6
Store excess water and pump
Contractile Vacuole
Special

14. Thinkables: Complete sentences.
Obviously the way a cell looks is different depending on the function. Do you think a cell will have differences in organelles depending on the function of that cell? Explain your answer. What organelle(s) would muscle cells need a lot of?
True/False: The nucleus of a cell contains different types of DNA depending on the structure and function of the cell for that organism. Explain your answer.
All cells have a phospholipid bilayer as a cell membrane. Thinking about the variety of shapes and sizes of cells what can you conclude about the cell membrane?

15. Cell Structures for Specialization
Flagellum- tail-like structure used for movement
Cilia- tiny hair-like structures used for movement
Microvilli- tiny hair-like structures used to increase absorption
Contractile vacuole- vacuole that pumps out excess water
Eyespot- structure used to locate sunlight for photosynthesis
phototaxis- movement towards sunlight
chemotaxis- movement towards a chemical

18. Stem Cells Stem Cells (3.02)
Draw the picture below on the white paper.
Are sperm and egg stem cells? Circle the cells that are undifferentiated stem cells.

19. Conclusion Continued…
Watch: What are stem cells?
Write a statement that describes stems cells. How are they different from other cells.
How can we use them to benefit humans?
