- 1. Cell Structure A ComprehensiveOverview
- 2. Introduction to theCell • - The cell is the basic unit of life and the building block of all living organisms. • - Types of Cells: • * Prokaryotic cells (e.g., bacteria). • * Eukaryotic cells (e.g., plant and animal cells).
- 3. Components of theAnimal Cell • 1. Plasma Membrane: • - Controls movement of substances in and out of the cell. • - Double layer of phospholipids. • 2. Nucleus: • - Contains DNA and regulates cell activities. • - Components: Nuclear envelope, nucleolus, chromosomes.
- 4. Animal Cell Organelles(Continued) • 4. Mitochondria: • - Produces energy in the form of ATP. • 5. Endoplasmic Reticulum (ER): • - Rough ER: Synthesizes proteins (with ribosomes). • - Smooth ER: Involved in lipid synthesis. • 6. Golgi Apparatus:
- 5. Components of thePlant Cell • 1. Cell Wall: • - Provides structural support and protection (cellulose). • 2. Chloroplasts: • - Site of photosynthesis (contains chlorophyll). • 3. Central Vacuole:
- 6. Comparison Between Animaland Plant Cells • | Feature | Animal Cell | Plant Cell | • |-------------------|--------------------|------------------ -----| • | Cell Wall | Absent | Present (Cellulose) | • | Chloroplasts | Absent | Present | • | Central Vacuole | Small or Absent | Large and Central |
- 7. Interactive Questions • 1.What is the function of mitochondria? • 2. What is the difference between rough and smooth ER? • 3. Which organelle is responsible for photosynthesis in plant cells?
- 8. Conclusion • - Thecell is the fundamental unit of life, crucial to understanding organism function. • - Studying cells is essential for advancements in medicine, agriculture, and science.
