3.2 Cellular Organization 3.2 Cellular Organization 3.2 Cellular Organization
  • A cell is highly organized and contains organelles that carry out specific functions.

  • The plasma membrane regulates the entrance and exit of molecules and ions into and out of the cell.

  • The nucleus, a centrally located organelle, controls the metabolic functioning and structural characteristics of the cell.

  • A system of membranous canals and vesicles works to produce, store, modify, transport, and digest macromolecules.

  • Mitochondria are organelles concerned with the conversion of glucose energy into ATP molecules

  • The cell has a cytoskeleton composed of microtubules and filaments; the cytoskeleton gives the cell a shape and allows it and its organelles to move.
