Cell Structure and Membrane Function

This content examines cell structure and organelles including the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, and chloroplasts, alongside the phospholipid bilayer of the plasma membrane.

  • Cell organelles
  • Nucleus and nucleolus
  • Smooth and rough endoplasmic reticulum
  • Golgi apparatus
  • Chloroplasts and photosynthesis
  • Mitochondria and cellular respiration
  • Centrioles and microtubule assembly
  • Cytoskeleton
  • Lysosomes
  • Cell wall
  • Plasma membrane structure
  • Fluid-mosaic model

Diffusion and Active Transport Mechanisms

Movement of molecules across semi-permeable membranes occurs through diffusion, facilitated diffusion, or active transport using ATP.

  • Diffusion
  • Concentration gradient
  • Passive transport
  • Equilibrium
  • Facilitated diffusion
  • Integral protein
  • Factors affecting diffusion rate
  • Active transport
  • ATP (adenosine triphosphate)
  • Carrier protein
  • Plasma membrane

Cell Membranes and Osmosis Mechanisms

Water moves across a semi-permeable membrane through osmosis, aided by aquaporins, while cells use exocytosis and endocytosis to move large molecules.

  • Osmosis
  • Hypotonic solution
  • Hypertonic solution
  • Isotonic solutions
  • Aquaporins
  • Exocytosis
  • Endocytosis
  • Phagocytosis
  • Vesicle
  • Surface area to volume ratios
