1. The Cell – Structure and Function Your Name Class Date

2. Introduction • A cell is the basic unit of life. • Discovered by Robert Hooke in 1665. • Two main types: Prokaryotic and Eukaryotic.

3. Types of Cells • Prokaryotic Cells: No nucleus, simpler (e.g., bacteria). • Eukaryotic Cells: Have a true nucleus (e.g., animal and plant cells).

4. Animal Cell Overview • Animal cells are eukaryotic. • They lack a cell wall. • Main parts: Nucleus, cytoplasm, and cell membrane.

5. Animal Cell Organelles • Nucleus • Mitochondria • Ribosomes • Endoplasmic Reticulum (Smooth & Rough) • Golgi Apparatus • Lysosomes • Cell Membrane

6. Functions of Each Organelle • Nucleus: Control center • Mitochondria: Energy production • Ribosomes: Protein synthesis • ER: Transport and synthesis • Golgi: Packaging • Lysosomes: Digestion • Membrane: Protection & transport

7. Plant Cell vs Animal Cell • Plant cells have a cell wall and chloroplasts. • Animal cells do not. • Vacuoles are larger in plant cells.

8. Importance of Cells • Responsible for growth, repair, energy production, and heredity.

9. Conclusion • Cells are essential for life. • Understanding cell types helps in studying biology.
