🧬 Quick Study Guide

  • 🦠 Cell Theory: πŸ’‘ All living things are composed of cells; the cell is the basic functional unit of life; cells arise from pre-existing cells.
  • 🧱 Cell Structures:
    • πŸ“¦ Cell Membrane: πŸ›‘οΈ Outer boundary, controls what enters and exits.
    • cytoplasm: 🌊 Jelly-like substance inside the cell.
    • nucleus: 🧠 Control center, contains DNA.
    • ribosomes: βš™οΈ Make proteins.
    • mitochondria: πŸ”₯ Powerhouse of the cell, produces energy (ATP).
    • endoplasmic reticulum (ER): 🚚 Transports materials within the cell.
      • rough ER: 🚧 Has ribosomes, involved in protein synthesis.
      • smooth ER: πŸ›’οΈ No ribosomes, involved in lipid synthesis.
    • golgi apparatus: πŸ“¦ Modifies, sorts, and packages proteins and lipids.
    • lysosomes: πŸ—‘οΈ Breaks down waste materials.
    • vacuoles: πŸ’§ Stores water, nutrients, and waste.
    • cell wall (plants only): 🌳 Provides support and protection.
    • chloroplasts (plants only): β˜€οΈ Site of photosynthesis.
  • 🌱 Prokaryotic vs. Eukaryotic Cells:
    • prokaryotic: 🦠 No nucleus or membrane-bound organelles (e.g., bacteria).
    • eukaryotic: πŸ„ Have a nucleus and membrane-bound organelles (e.g., animal, plant, fungi, protists).
  • πŸ”„ Cellular Processes:
    • diffusion: πŸ’¨ Movement of molecules from high to low concentration.
    • osmosis: πŸ’§ Movement of water across a semipermeable membrane.
    • active transport: πŸ’ͺ Requires energy to move molecules against a concentration gradient.
