Carbon, water, and oxygen are the most important elements for life. Water is found in all living cells. An organism's metabolism refers to its ability to use energy for daily functions. The cell theory states that all living things are made of cells, cells are the basic functional units of life, and all cells come from pre-existing cells. The three scientists most responsible for developing cell theory are Theodore Schwann, Matthias Schleiden, and Rudolf Virchow. Cellular organization refers to cells being the basic units that make up and carry out functions of living things. Multicellular organisms are composed of more than one cell, with cells often organized into tissues, organs, and organ systems that may perform
