Vocabulary:
1.Classification- putting things into orderly groups based on similar characteristics.
2.taxonomy- the science of describing, classifying, and naming living things.
3.dichotomous key- a identification aid that uses sequential pairs of descriptive statements.

Section 1:Classification Summary
In this section it discussed mostly all about classification. It talked about how scientists classify organisms, classification today,levels of classification, scientific names, two-part names, and .dichotomous keys. Scientist classify organisms use taxonomy which was founded by a Swedish scientist, Carolus Linnaeus. Taxonomy is the science describing, classifying, and naming living things.Taxonomists use an eight-level system to classify living things based on shared characteristics. The eight levels of classification are domain, kingdom, phylum, class, order, family, genus, and species. The two-part names are used for the genus and specific. Lastly it taled about a dichotomous key and how it helps scientist identify organisms.
This is a picture of classification through grizzly bears, black bears, giant panda, red fox, squirrels, coral snakes, and sea stars.
Section 2:Domains and Kingdoms:Vocabulary
1.Archaea- in a modern taxonomic system, a domain made up of prokaryotes that differ from other prokaryotes in the makeup of their cell walls and their genetics.
2.Bacteria- in a modern taxonomic system, a domain made up of prokaryotes in the makeup of their cell walls and in their genetics.
3.Eukarya- in amodern taxonomic system, a domain made up of all eukaryotes.
4.Protista- a kingdom of mostly one-called eukaryotic organisms that are different from plants, animals, and fungi.
5.Fungi- a kingdom made up nongreen, eukaryotic organisms that have no means of movement,reproduce by using spores, and get food by breaking substances intheir surroundings and absorbing the nutrients.
6.Plantae- consists of organisms that are eukaryotic, have cell walls, and make food through photosynthesis.
7.Animalia- contains complex, multicellular organisms that don't have cell walls, are usually able to move, and have specialized sense organs.

Section 2: Domains and Kingdoms: Summary
Section 2 was mostly about kingdoms and domains.there are three domains; Archaea, Bacteria, and Eukarya. There are four kindoms; Protista, Fungi, Plantae, and Animalia. Archaea aligns withthe traditional kindom Archeabacteria. Bacteria aligns with the traditional kingdom Eubacteria. Eukarya aligns with the traditional kingdoms Protista, Fungi, Plantae,and Animalia. In the end it discussed about strange organisms and classifying unusual organisms.Such as sponges.
