Two basic kind of cells are cells without a nucleus and cells with a nucleus.                   Section1.2- The three types of compounds contained in a cell membrane are lipids,phospholipid,and proteins. A lysosome are organelles that contain digestive enzymes. Proteins are made of amino acids.                   Section1.3-  Mussel tissue makes food move in and through the stomach.
