The cell membrane is very important to the cell structure. It helps hold everything within the cell and serves as a protective covering as well.
Biology is the study of life, and uses the scientific method, the basis of science, to do so. Hypotheses are made, tested, and remade, until a theory is made, which then becomes Scientific law.
iconic bond -> sharing of many electrons
metallic bond -> sharing of electrons
covalent -> transferring of electrons

The Mitochondria in many cells, are believed to have been bacteria that have been incorporated in the cytophysiology. Mitochondria first off, contain their own DNA, er, RNA. Additionally physiologically the mitochondrion, has an inner membrane and some organelle traits similar to prokaryotic cells. Lastly Mitochondria are the only organelle capable of replicating itself. <span />
