Characteristics Of Living Organisms
Akopọ
How do you tell something that is alive from something that is not? A rock and a mushroom, a candle flame and a cell: each pair can look similar at a glance, yet only one of each is truly living. Biologists settle the question with a checklist of seven life processes that every living organism, from a single bacterium to a blue whale, carries out.
In this lesson you will learn those seven characteristics and the precise definition of each, captured by the well known memory aid MRS GREN. By the end you will be able to define every process in exam language and decide, with reasons, whether any given thing counts as a living organism.

- Describe the characteristics of living organisms by describing: (a) movement as an action by an organism or part of an organism causing a change of position or place (b) respiration as the chemical reactions in cells that break down nutrient molecules and release energy for metabolism (c) sensitivity as the ability to detect and respond to changes in the internal or external environment (d) growth as a permanent increase in size and dry mass (e) reproduction as the processes that make more of the same kind of organism (f) excretion as the removal of the waste products of metabolism and substances in excess of requirements (g) nutrition as the taking in of materials for energy, growth and development
