Study Notes
Typical Animal Cell
- Cytoplasm: The watery fluid inside the cell containing organelles.
- Nucleus: The control center of the cell, containing DNA for protein synthesis.
- Ribosomes: Tiny structures that make proteins following instructions from DNA.
- Rough Endoplasmic Reticulum (Rough ER): Folded membranes with attached ribosomes, responsible for protein production and transport.
- Smooth Endoplasmic Reticulum (Smooth ER): Folded membranes without ribosomes, involved in detoxification and lipid production.
- Golgi Apparatus: Packages and modifies proteins for export or use within the cell.
- Mitochondria: Double-membrane organelles that generate energy (ATP) through cellular respiration, using glucose and oxygen.
- Lysosomes: Membrane-bound sacs containing enzymes for breaking down waste materials.
- Vacuoles: Storage compartments for various materials, often large in plant cells for water storage.
- Cell membrane: A phospholipid bilayer regulating the passage of molecules in and out of the cell, maintaining homeostasis.
Typical Plant Cell
- Chloroplasts: Double-membrane organelles found only in plant cells, containing chlorophyll for photosynthesis.
- Cell Wall: A rigid outer layer providing support and protection to the plant cell, primarily composed of cellulose.
Typical Bacteria Cell
- Cell Wall: Provides structural support and protection.
- Cell Membrane: Regulates the entry and exit of molecules.
- Cytoplasm: The fluid that fills the cell, containing organelles.
- Ribosomes: Responsible for protein synthesis.
- DNA: A circular molecule containing the cell's genetic information.
- Flagellum: A whip-like structure used for movement.
Organelles
-
Endoplasmic Reticulum (ER): A network of membranes essential for protein synthesis and lipid production.
- Rough ER: Has ribosomes attached for protein production.
- Smooth ER: Lacks ribosomes and focuses on lipid production and detoxification.
- Ribosomes: The sites of protein synthesis.
- Mitochondria: The "powerhouses" of the cell, responsible for energy (ATP) production.
- Lysosomes: Membrane-bound organelles containing enzymes that break down cellular waste.
- Vacuoles: Storage compartments for various materials, often large in plant cells for water storage.
Cell Membrane Structure
- The cell membrane is a phospholipid bilayer with embedded proteins that regulate the movement of molecules in and out of the cell.
- The membrane also contains cholesterol, which helps maintain its structure.
