Cell Structure

Cell Functions

  • Mitochondria- The cells "powerhouse"
  • Nucleus- Controls the activities of the cell.
  • Nuclear membrane- Controls what enters and leaves the membrane.
  • Nucleolus- Contains all the DNA of the cell.
  • Cell membrane- Protects the interior of the cell.
  • ER- Ships proteins.
  • Cell Wall- Provides protection.
  • Cytoplasm- Supports and protects cell organelles.
  • Vacuole- Stores large amounts of sugar and food.
  • Chloroplast- Releases oxygen, photosynthesis.
  • Golgi Body- Package and exports proteins.
  • Ribosomes- Makes proteins.
  • Chromosome- Carry all the info a cell needs to grow.


Cell Transport

  • Passive transport requires no energy because the movement is from high to low concentration.
  • Diffusion is random movement of molecules from high to low concentration.
  • Osmosis is the diffusion of water across a semi permeable membrane.
  • Facilitated diffusion is the helper protein. It allows movement form high to low concentration.
  • Active transport uses energy (ATP) Low to high concentration.
