  1. Metabolism - is about all the chemical reactions present in an organism - one of which is the organism’s ability to break down food molecules to be utilized as a source of energy and raw materials to synthesize its own molecules. Example: Dissolves a piece of bread into simple nutrients your body can use, like glucose.

  2. Responsiveness - the ability of an organism to sense changes in its external or internal environment and be able to adjust to those changes. Example: How the body maintains its internal temperature to different limits despite great fluctuations within us in daily temperature. 

  3. Movement - refers to the motion of the entire body, single cells including tiny structures inside the cell, and individual organs. Example: Circumduction is a movement of the limb, hand, or fingers in a circular movement, through the sequential combination of flexion, adduction, extension, and abduction motions. 

  4. Growth - refers to the size or number of cells increase that produces an overall enlargement of all or part of an organism. Example: When a human is exercising, its muscle enlarges composed of larger muscle cells than those of an untrained muscle.  

  5. Differentiation - refers to the changes an organism undergoes through time. Also, it is the development of a cell from an unspecialized to a specialized state. Example: A stem cell is an unspecialized cell that can be divided limitless within specific conditions, and differentiate into specialized cells. Such as, stem cells turning into neurons, osteocytes, or cardiomyocytes. 

  6. Reproduction - refers to the formation of new cells or organisms for tissue growth, repair, or replacement. Being able to produce organisms, species will not undergo extinction. Example: The female’s ovary produces an egg (oogenesis) while the male produces sperm (spermatogenesis).
