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. |
