TermDefinition
6 Kingdoms of Life Archaea Bacteria Protista Fungi Plantae Animalia
Achaea The kingdom of prokaryotes that includes methanogen, which manufactures methane. Known for living in extremely harsh conditions.
Bacteria Second of the two prokaryotic kingdoms.
Protista Most of the unicellular eukaryotes (those whose cells contain a nucleus) are grouped into this kingdom. Includes the multicelular algae.
Fungi Kingdom that contains non-photosynthetic organisms, mostly multicellular, that digests their food externally
Plantae Kingdom that contains photosynthetic, multicellular organisms that are primarily terrestrial
Animalia Kingdom that contains nonphotosynthetic multicellular organisms that digest their food internally
The Unifying Properties of Life Cellular organization Metabolism Homeostasis Growth and reproduction Heredity
Cellular Organization All living things are composed of one or more cells
Metabolism All living things use energy. The transfer of energy from one form to another in cells is a form of metabolism.
Homeostasis A function in which organisms keep their internal conditions relatively constant
Growth and reproduction All living things grow and reproduce
Heredity All living things posess a genetic system that is based on DNA
Gene A set of directions within DNA
Population level order of complexity Population Species Community Ecosystem
Emergent Properties The results of an increasing complexity of the structural organization and hierarchy of life.
5 Biological Themes Evolution The Flow of Energy Cooperation Structure Determines Function Homeostasis
Four Theories Unifying Biology as a Science Cell Theory Gene Theory The Theory of Heredity The Theory of Evolution
Cell Theory All living things are made up of one or more cells. Cells are the basic units of life.
Theory of Evolution Many forms of a gene may exist in members of a population, but the ones whose gene's give them traits better-suited to their particular habitat will tend to reproduce more successfully and make their genes become more common in the populations.
Gene Theory The proteins and RNA molecules encoded by an organism's genes determine what it will be like
Three Domains of Life Bacteria (Kingdom Bacteria) Archaea (Kingdom Archaea) Eukarya (Kingdoms Protista, Plantae, Fungi, and Animalia)
Theory of Heredity The genes of an organism are inherited as discrete units
Chromosomal Theory of Inheritance The genes of Mendel's theory are physically located on chromosomes, and it is because chromosomes are parceled out in a regular manner during reproduction that Mendel's regular patterns of inheritance are seen.
