Objective SWBAT describe characteristics of organisms in kingdom

Objective • SWBAT describe characteristics of organisms in kingdom Eubacteria.

Kingdom Eubacteria • Eubacteria are single-celled. – Unicellular • Eubacteria are prokaryotes. – Their cell does not have a nucleus. • Some are autotrophs; some are heterotrophs. • Eubacteria everywhere – except the extreme places archaebacteria live.

Check For Understanding • What is an autotroph? A. A car. B. An organism that gets energy from eating other organisms. C. An organism that gets energy from decomposing other organisms. D. An organism that produces its own energy.

Cyanobacteria

Escherichia Coli (E. Coli)

Salmonella

What are two things you see in this diagram that let you know this organism could be in kingdom Eubacteria?

Check For Understanding • Which statement below correctly describes something Archaebacteria and Eubacteria have in common? A. They are both unicellular. B. They are both eukaryotic. C. Neither of them have DNA. D. They both live in extreme environments.

Types of Eubacteria • Eubacteria are classified according to how they get energy. – Consumers eat other bacteria – Decomposers break down big organisms and get their energy. – Producers make energy from sunlight. • Cyanobacteria have chlorophyll – they get energy from sunlight, like plants.

Check For Understanding • Which of the following is NOT true of Eubacteria? A. They are made of one cell. B. They live everywhere but are too small to see. C. They have a nucleus. D. They can be autotrophs or heterotrophs.

Eubacteria • Cell number: Unicellular (one cell) • Cell type: Prokaryotic (no nucleus) • How does it get energy? : Autotrophs and heterotrophs • Key attributes: Live everywhere. • Examples: Cyanobacteria, E. coli, Salmonella
