4.2: Eukaryotic Cells Have Internal Membranes That Compartmentalize Their Function & 4.3: The Eukaryotic Cell's Genetic Instructions Are Housed in the Nucleus and Carried Out by the Ribosomes 

You Must Know: 

• Three differences between prokaryotic and eukaryotic cells.
• The structure and function of organelles common to plant and animal cells.
• The structure and function of organelles found only in plant cells or only in animal cells.
• How different cell types show differences in subcellular components
• How cell size and shape affect the overall rate of nutrient intake and waste elimination

Key Terms: Plasma Membrane, Nucleus, Nuclear Envelope, Chromatin, Nucleolus, Ribosomes

IN CLASS READING of Concepts 4.2 - 4.3: Pages 75-82

1. Define the Key Terms above.
2. Create a 3 column table that identifies which of the following characteristics are found in Prokaryotic Cells and/or Eukaryotic Cells
• Plasma Membrane
• Ribosomes
• Membrane-bound organelles in cytosol
• Nucleus
• Size 1µm - 10µm
• Size 10µm - 100µm
3. Decide whether the following subcellular components belong to a plant OR an animal cell: Lysosomes, Chloroplasts, Central Vacuoles, Centrioles, Cell Wall, Flagella, Plasmodesmata
4. Explain why cells must be small using the concept of surface area to volume ratio.
5. Determine why the book says that MOST of a eukaryotic cell's DNA is located in the nucleus. 
6. Name 3 things that may exit the nucleus through pores.
7. Propose an argument for which one of those things is the most important for the cell.
8. State what ribosomes make for the cell. 
9. List the 2 parts of a ribosome.
10. Compare and contrast free ribosomes with bound ribosomes.
11. State the nucleic acid that is "read' by the ribosome during translation.
12. Explain how the fact that ribosomes are found in all forms of life on our planet supports the idea of common ancestry of all known life.
