• Movement
  • an action by a living organism to bring a change in the position of the organism.
• Respiration
  • the chemical reactions in cells that break down nutrient molecules and release energy for metabolism
• Sensibility
  • ability to detect or sense stimuli in the interial or external environments.
• Growth
  • a permanent increase in size and dry mass by increasing cell size and/or cell number.
• Reproduction
  • to make more of the same kind of organism.
• Nutrition
  • consumption of materials for energy, growth and development
• Excretion
  • the process by which organisms expel metabolic waste products and other toxic substances from their body

Concept & Uses of classification System

• A species is a group of organisms that can reproduce to produce fertile offspring.
• Organisms are classified in a way that allows subdivision of living things into smaller and more specialised groups. The species in these groups have more common features the more subdivided they get.
• Organism were named using the binomial system in Latin. The name is made up of 2 parts;
  • the genus (starts with capital letter) followed by
  • the species (in lower case).
  • Binomial names are typed in italics.

Phylogenetic Trees

• Phylogenetic trees are diagrams that display the evolutionary history of species or groups of organisms
• These Trees are built using morphology, behavior, dna and biochemistry.
• A taxonomy groups organisms based on similarities, the image above is a taxonomy

This is an example of a phylogenic tree

Dichotomous keys

Keys are used to identify organisms based on a series of questions about their features. 2 descriptions are given about their features and a choice has to be made to determine the species, genus, and/or family, etc.
