Term
nucleus
Definition
  • control center for the cell
  • surrounded by a membrane (nuclear membrane)
  • contains nucleolus
  • life process=regulation
Term
nucleolus
Definition
  • a dense area inside the nucleus
  • contains the DNA
  • life process=regulation
Term
cell membrane
Definition
  • separates the cell from its outer enviornment
  • controls what enters and leaves the cell
  • called "selectively permeable"
  • life processes=regulation, transport, and excretion
