Movement:

Movement An action by an organism or part of an organism causing a change of position or place.

Respiration:

Respiration The chemical reactions that break down nutrient molecules in living cells to release energy NOT BREATHING Types of respiration Aerobic (with air) Anaerobic (without air)

Sensitivity/Irritability :

Sensitivity/Irritability The ability to detect or sense changes in the environment (stimuli) and to make responses.

Growth:

Growth A permanent increase in size and dry mass by an increase in cell number or cell size or both.

Reproduction:

Reproduction The processes that make more of the same kind of organism

Excretion:

Excretion The removal from organisms of toxic materials, the waste products of metabolism (chemical reactions in cells including respiration) and substances in excess of requirements.

Nutrition:

Nutrition The taking in of nutrients which are organic substances and mineral ions, containing raw materials or energy for growth and tissue repair, absorbing and assimilating them.
