The basic unit of all life.
In this unit we will answer the following questions:
1. How does a microscope work?
2. What are cells?
3. How is cell structure related to cell function?
4. How do cells communicate?
5. Why do cells have so many parts?
6. How do cells look under a microscope?
7. How can we measure the size of cells?
8. What are the parts of cells?
9. What is the stucture and function of each part?
10. What are the differences between plant and animal cells?
11. What is diffusion?
12. What is the difference between active and passive transport?
13. Why are all cells so small...or are they?
14. How are organic and inorganic molecules different?
15. How does cellular respiration release food energy?
16. What is photosynthesis?
17. What are enzymes and how do they work?
18. How do cells divide?
This is what you should know at the end of this unit (Thanks Mr. Buckley)
1. discuss and compare the following relative organizational levels; cell, tissue, organ,
and organ systems.
2. recognize that improvements in the light microscope and microscopic techniques
during the last four centuries have allowed the development of the cell theory.
3. state the cell theory.
4. convert micrometer measurements to millimeters and vice versa.
5. describe the appearance and chief function(s) of the following organelles found in
both plant and animal cells; nucleus, nuclear membrane, nucleolus, ribosomes,
endoplasmic reticulum, cytoplasm, food vacuole, contractile vacuole, lysosome,
mitochondrion, golgi apparatus, and plasma membrane.
6. relate the structure of the plasma membrane to its function.
7. discuss the role of the centriole in animal cells.
8. state the role of the cell wall and chloroplasts in plant cells.
9. define the following terms associated with processes of the plasma membrane;
diffusion, concentration gradient, osmosis, solute, solvent, permeability, and
10. given osmotic situations, correctly indicate the direction of osmotic flow and explain
why this is so.
11. explain the differences between passive transport and active transport.
12. explain the difference between pinocytosis and phagocytosis.
