1. 10/3 Warm Up Match the scientist with the theory: C A B E D
A. Schleiden B. Schwann C. Hooke
D. Van Leeuwenhoek E. Virchow
1. First discovered cells in cork
2. Plant tissues are composed of cells
3. Animal tissues are composed of cells
4. Cells come from pre-existing cells
5. Improved the microscope C A B E D

2. 10/4 Warm Up 1. What is the function of the smooth ER?
2. What is the function of the centrioles? What type of cell are they in?
3. What is the function of the nucleolus?
4. What is the function of the cell membrane?
5. How does the cytosol compare to the cytoplasm?
Lipid synthesis, detoxification & calcium regulation
Role in cell division; animals ONLY
Ribosome production
Due to the phospholipids it is selectively permeable
Cytoplasm = cytosol (cell gel) + organelles

3. Practice!

4. 10/5 or 10/6 Warm Up
Determine which organelles would have the highest concentration for each scenario.
1. Nerve cells are very active; they need a lot of energy and thus, they have large numbers of __________ in order to be supplied quickly with large amounts of ATP.
2. Pancreatic cells are making large amounts of enzymes, therefore they would need a large number of _________.
3. Immune cells that destroy bacteria with chemicals need an abundance of _________.
4. Testes and ovaries that make steroids (lipids) would have a large amount of______________.
mitochondria
ribosomes
lysosomes
Smooth ER
