Sample Content: Cell Structure and Function
Cell Theory
- All living organisms are composed of cells.
- The cell is the basic unit of life.
- All cells arise from pre-existing cells.
Types of Cells
- Prokaryotic Cells: No nucleus; examples include bacteria.
- Eukaryotic Cells: Have a nucleus; includes plant and animal cells.
Organelles and Their Functions
| Organelle | Function |
|---|---|
| Nucleus | Contains DNA; controls cell activities |
| Mitochondria | Produces energy (ATP) through respiration |
| Ribosomes | Protein synthesis |
| Endoplasmic Reticulum (ER) | Rough ER: protein modification; Smooth ER: lipid synthesis |
| Golgi Apparatus | Processes and packages proteins |
| Lysosomes | Digestion and waste removal |
| Chloroplasts (plant cells) | Photosynthesis |
| Cell Membrane | Regulates what enters and leaves the cell |
| Cell Wall (plant cells) | Provides protection and structure |
Cell Membrane Transport
- Diffusion: Movement of molecules from high to low concentration.
- Osmosis: Diffusion of water across a semi-permeable membrane.
- Active Transport: Movement of molecules against concentration gradient using energy.
Suggested Activities and Experiments
- Microscope observation of plant and animal cells.
- Modeling enzyme activity and effects of temperature and pH.
- Simulating diffusion and osmosis using dialysis tubing.
- Performing Mendelian genetics crosses using Punnett squares.
Assessment Ideas
- Multiple-choice quizzes
- Lab reports
- Group presentations on specific organelles or metabolic processes
- Essays on topics like the importance of cell division or evolution
