Biology Typical Animal Cell Quiz

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.
