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
