Ch. 6 Cell Structure pt. 1 Intro to cell evolution and class

cell

the fundamental unit of biological organization

Unicellular

Made of a single cell

Multicellular

Made up of more than one cell.

Prokaryotic

more simple first evolution, doesn't have a nucleus, smaller and only exists as unicellular

Eukaryotic

More complex, arose from prokaryotic cells, larger, has an organelle called a nucleus contains DNA, can exist uni or multicellular

unity of life

is explained by descent from a common ancestor

Mutation

a random error in gene replication that leads to a change

natural selection

A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.

Evolution involves

Heritable Variation, natural selection, and adaptation

common ancestor

when 2 species, usually correct to say neither species evolved from each other but share 1 specie

4 kingdoms of eukarya

Protista, Fungi, Plantae, Animalia

Domains

Bacteria, Archaea, Eukarya. The highest level of biological classification.

Taxonomy

the field of biology that organizes and groups different spaces

Carolus Linnaeus

Proposed the hierarchical scheme we continue today.
