Concepts
1. Know which accomplishments Antoni van Leeuwenhoek and Robert Hooke are known for, and the approximate time
they lived.
2. Know how Matthias Schleiden, Theodor Schwann, and Rudolf Virchow contributed to the Cell Theory, and the
approximate time they lived.
3. State all three parts of the Cell Theory.
4. Describe the difference between a light microscope and an electron microscope.
5. Describe the difference between the two types of electron microscopes (TEM and SEM).
6. List the four things all cells have in common.
7. List the major differences between prokaryotes and eukaryotes.
8. List the major differences between plant and animal cells.
9. Know the name, location, and function of the following organelles: cell membrane, cytoplasm, nucleus, nuclear
envelope, nuclear pore, nucleolus, vacuole, vesicle, lysosome, cytoskeleton, centriole, cilia, flagella, ribosome, RER,
SER, Golgi apparatus, chloroplast, mitochondria, and cell wall.
10. Compare and contrast cilia and flagella.
11. Describe the fluid mosaic model.
12. Give some reasons for why cells need to transport materials into and out of cells.
13. List what kind of substances can and cannot cross easily through the lipid bilayer.
14. Explain the difference between simple diffusion and facilitated diffusion.
15. List two ways that active transport is different from passive transport.
16. Know why osmosis is a special type of diffusion.
17. Understand how hypertonic, hypotonic, and isotonic environments affect water movement into and out of cells, and
what the consequences can be for cells (Shrivel? Fill with water?)
18. Indicate why animal cells have a different reaction to osmotic pressure than plant cells.
19. Explain the process of endocytosis, and its reverse, exocytosis.
