    • 2005, David A Guertin and David M Sabatini, chapter "Cell Size Control" in Encyclopedia of Life Sciences, Wiley:
      Since protein constitutes the majority of the biomass of a cell, building new protein is a major way that cells increase their size.
  2. The total mass of all living things within a specific area, habitat etc.
  3. Vegetation used as a fuel, or source of energy, especially if cultivated for that purpose.
