Biology | The study of living organisms. |
Metablolism | Rrocesses that occur in a living organism in order to stay alive. |
Life | Existence of an individual human being or animal. |
Aerobic | Relating to, involving or requiring free oxygen. |
Anaerobic | Relating to, involving, or requiring the absence of free oxygen. |
Organism | An individual animal, plant, or single-celled life form. |
Life processes | Essential actions to determine if an animal is alive: movement,respiration,sensitivity, growth,reproduction, excretion and nutrition. |
Sexual | relates to the physiological processes, activities connected with physical attraction or intimate physical contact between individuals. |
Homeostasis | The stable equilibrium between interdependent elements, especially as maintained by physiological processes. |
Asexual | Without sexual feelings or associations. |
Biotic | Results from living things, especially in their ecological relations. |
G.R.R.R.N.E.T.S. | Growth,Reproduction,Respiration, Regulation,Nutrition,Excrecion,Transportation and Sinthesys-assimilation. |
Growth | the process of increasing in physical size. |
Reproduction | The production of offspring by a sexual or asexual process. |
Respiration | Action of breathing. |
Regulation | Action of controlling maintain as is. |
Nutrition | The process of providing or obtaining the food necessary for health and growth. |
Excrecion | The process of eliminating or expelling waste matter. |
Transportation | The action of transporting someone or something or the process of being transported. |
Synthesis-Assimilation | The production of chemical compounds by reaction from simpler materials. |

Prokaryote | A microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. |
Eukaryote | An organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. |
Autotrophyc | An organism capable of producing its own food from inorganic substances using light or chemical energy: Green plants, algae, and certain bacterias. |
Heterostrophyc | An organism that cannot produce its own food and instead obtains its food and energy by taking in organic substances, usually plants: animals,protozoans, fungi, and most bacteria are heterotrophs. |
Ingestion | The act of taking food and drink into the body by the mouth. The taking in of particles by a phagocytic cell. |
Digestion | The process of breaking down food by mechanical and enzymatic action in the alimentary canal into substances that can be used by the body. |
Egestion | The discharge or expulsion of undigested material (food) from a cell in case of unicellular organisms, and from the digestive tract via the anus in case of multicellular organisms. |
Aerobic | Relating to, involving, or requiring free oxygen. |
Anaerobic | relating to, involving, or requiring an absence of free oxygen. |
