Biologists use classification to organize living things into groups so that organisms are easier to study.1. How many cells does the organism have?2. Is a nucleus present?3. How does the organism obtain its energy?4. How does the organism reproduce?

Classification- The process of grouping things based on

similarities

1. How many cells does the organism have?

Unicellular or multicellular2. Is a nucleus present?

Prokaryote or eukaryote3. How does the organism obtain its energy? Autotroph or heterotroph4. How does the organism reproduce?

Sexual reproduction or asexual reproduction

To help scientists classify organisms, they ask themselves these four questions:

Eight levels of Classification

Page 5: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

The broadest category of classification. There are three domains in which organisms are classified.

1. Eukarya2. Archea3. Eubacteria

Domain

Page 6: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

Eukarya is the Domain that all eukaryotes (organisms with an organized nucleus) are classified under. This Domain includes four Kingdoms:

1. Animalia2. Plantae3. Fungi 4.Protista

Eukarya

Page 7: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

The next two Domains classify all organisms that are prokaryotes

(do NOT have an organized nucleus)

Page 8: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

The Domain that all Archaebacteria are classified under. Approximately 4% of all organisms are Archaea. It is

believed that there are about 600,000 Archaea species. These include bacteria that live in extreme environments

such as arctic temperatures, hot springs, and volcanic vents.

The environment where these organisms live is a major characteristic that separates these bacteria from all other bacteria.

This domain only includes one Kingdom: Archaebacteria.

Archaea

Page 9: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

The Domain that all other bacteria are classified under.

Approximately 7% of all organisms are Eubacteria. There are estimated to be about 1 million types of bacteria of which only 4,000 have been identified.

These include bacteria that are decomposers and nonharmful bacteria that help our bodies, as well as disease causing bacteria.

This Domain only includes one Kingdom: Bacteria

Eubacteria

Page 10: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

The second broadest category of classification is the Kingdom. There are 6 kingdoms in which all organisms are classified. 1. Animalia2. Plantae3. Fungi4. Protists5. Eubacteria6. Archeabacteria

Kingdom

Page 11: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

Dogs, cats, fleas, and sea coral are examples of animals.

They are multicellular eukaryotes that are heterotrophs (consumers).

Most, but not all, animals can move from one place to another.

Most reproduce sexually, but some may be asexual (sea anemones).

Animalia/ Animals

Page 12: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

Are multicellular, eukaryotes. All are autotrophs (producers), but in a

few rare cases, some are also heterotrophs (Venus flytrap); however, they do not get their energy from the flies they trap.

Some plants produce flowers, while others do not.

Plantae

Page 13: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

Includes organisms such as mushrooms, molds, and yeast.

They are eukaryotes. Many are multicellular, but some are unicellular.

All are heterotrophs. Most feed on dead or decaying organisms. They are found almost everywhere on land, but

some live in water. They can reproduce sexually or asexually.

Fungi

Page 14: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

Protista are eukaryotes. Some are unicellular, and some are

multicellular. Many of these organisms are microscopic

such as Amoeba, Paramecium, and Euglena. Some are autotrophs and others are

heterotrophs. They can reproduce sexually or asexually.

Protista

Page 15: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

Are unicellular prokaryotes that can be helpful or harmful.

Bacteria in yogurt or your digestive system can be helpful, while bacteria that cause diseases such as E. coli or Salmonella can be harmful.

Some of these bacteria are decomposers which play an important and helpful role in our ecosystem. Some are autotrophs while others are heterotrophs.

They reproduce asexually. They live in moderate environments.

Eubacteria

Page 16: TAXONOMY~ CLASSIFICATION. Biologists use classification to organize living things into groups so that organisms are easier to study. 1. How many cells.

Are unicellular prokaryotes that live in extreme environments such as volcanic vents, arctic temperatures, and hot springs.

Some examples are halophiles and thermophiles.

They can be autotrophic or heterotrophic. They reproduce asexually.

Archeabacteria
