Theory of biological organization, which has three tenets: all organisms are made up of one or more cells; the cell is the structural unit of life; cells only arise from the division of preexisting cells. Toughest body cell systems, bound together by calcium and phosphate. Give strength, support, and frame work to the body by enclosing organs in skeletal system. Present in large bones to help them bend/move freely. Found in brain and spinal cord, combine to form the nervous tissue. Rich in actin and myosin, have the ability to contract/relax providing movements. Cells form covering layers of all the organs. Red blood cells, white blood cells, thrombocytes (platelets) Conduct electrical impulse from region to region (nerve cells, muscle cells) Stores materials like fat for later use (adipose cells) Specialized for important functions (sperm, oocytes, stem cells, rods/cones, ciliated cells, blood cells) When one organism enters another and engages in a mutually beneficial relationship.
