Chapter 2: Cell Structure and Function Assignment1. Describe the structure and function of the cell membrane.The cell membrane is a phospholipid bilayer with embedded proteins. It regulates what entersand exits the cell.2. Explain the differences between plant and animal cells.Plant cells have a cell wall, chloroplasts, and a large central vacuole, whereas animal cells lackthese structures and have centrioles.3. What is the role of ribosomes in a cell?Ribosomes synthesize proteins by translating messenger RNA.4. Compare and contrast the functions of the smooth and rough endoplasmic reticulum.The rough ER has ribosomes and is involved in protein synthesis, while the smooth ER isinvolved in lipid synthesis and detoxification.5. What is the function of the mitochondria?Mitochondria are the site of cellular respiration, producing ATP, the energy currency of the cell.6. Define osmosis and its importance to cells.Osmosis is the diffusion of water across a semipermeable membrane. It is crucial formaintaining cell turgor and homeostasis.7. Describe the role of lysosomes in a cell.Lysosomes contain enzymes that break down waste materials and cellular debris.8. What are the differences between cilia and flagella?Cilia are short, hair-like structures for movement or moving fluids, while flagella are long,whip-like structures used for cell propulsion.9. Explain the function of the Golgi apparatus.The Golgi apparatus modifies, sorts, and packages proteins and lipids for transport or secretion.10. How do chloroplasts contribute to the survival of plants?
Chloroplasts carry out photosynthesis, converting light energy into chemical energy stored inglucose.
