Centrioles –organelles in the cell that help to move chromosomes during cell division chromatin –what you call the dna during interphase, very easy to access the genes for transcription and translation to create proteins chromosome –what you call the dna during the actual cell division stages (pro-, meta-, ana-, and telophase. Cell growth is limited for two reasons: if the cell size continues to increase, an information overload will occur because the size is increasing but the dna is not diffusion will not be able to occur if the cell membrane area is too large because important materials cannot reach the cell.
