Characteristic of living things
Movement: an action made by an organism causing a change in place/position
Respiration: chemical reactions that take place in cells that break
metabolism
down nutrient molecules and release energy for
Sensitivity: is the ability to sense stimuli in internal or external environment and make appropriate responses to them
Growth: Permanent increase in size and dry mass by an increase in cell number, cell size, or both
Reproduction: The process of making more individuals of the same type of organism to maintain the population of this
type
Execration: Removal of toxic materials, waste products of metabolism, and substances in excess of requirements from the
organism’s body
Nutrition: Taking in nutrients which are organic substances and mineral ions containing raw materials used to release
energy by respiration used for growth, development, and tissue repair and then absorbing and assimilating them
Species: group of organisms that can reproduce to produce fertile offspring
A glance into the classification of organisms
Binomial Naming system:
→ Way to make classification standard
→ Scientific name consists of Genus and species
Why do we classify organisms??
→ To identify those who are in risk of extinction
→ To understand evolutionary relationships
How to classify organisms??
By morphology and anatomy!
Morphology→ study of form or outward appearance of an organism
Anatomy→ study of internal structure by dissection
→ Sequences of DNA and amino acids in proteins are a more accurate way
of classification
→ Each species has its unique number of chromosomes and sequence of
bases in DNA
making it different from other species (humans have 46 chromosomes)
→ Organism with recent ancestors have DNA that's more similar than
distant
