Cell Theory - Modern Interpretation

Modern Interpretation

The generally accepted parts of modern cell theory include:

  1. All known living things are made up of one or more cells.
  2. All living cells arise from pre-existing cells by division.
  3. The cell is the fundamental unit of structure and function in all living organisms.
  4. The activity of an organism depends on the total activity of independent cells.
  5. Energy flow (metabolism and biochemistry) occurs within cells.
  6. Cells contain hereditary information (DNA) which is passed from cell to cell during cell division.
  7. All cells are basically the same in chemical composition in organisms of similar species.

Famous quotes containing the word modern:

    “Though collecting quotations could be considered as merely an ironic mimetism—victimless collecting, as it were ... in a world that is well on its way to becoming one vast quarry, the collector becomes someone engaged in a pious work of salvage. The course of modern history having already sapped the traditions and shattered the living wholes in which precious objects once found their place, the collector may now in good conscience go about excavating the choicer, more emblematic fragments.”
    —Susan Sontag (b. 1933)
