1.1) Characteristics of living organisms
Movement: is an action by an organism or part of an organism causing a change of position or place.
Respiration: describes the chemical reactions in cells that break down nutrient molecules and release energy for metabolism.
Sensitivity: is the ability to detect or sense stimuli in the internal or external environment and to make appropriate responses.
Growth: is a permanent increase in size and dry mass by an increase in cell number or cell size or both.
Reproduction: is the processes that make more of the same kind of organism.
Excretion: is the removal from organisms of the waste products of metabolism (chemical reactions in cells including respiration), toxic materials and substances in excess of requirements.
Nutrition: is the taking in of materials for energy, growth and development. Plant require light, CO2, H2O and ions. Animals need organic compounds and ions and H2O.
