Warm-Up

Explain how a cell could change? Use the words protein, DNA, and mutation.

Prokaryote

Extremophile

Vocabulary

If bacteria reproduce asexually, are there different kinds of bacteria? Let’s find out!

Bacteria

Eubacteria and archaebacteria

Eubacteria and archaebacteria

•Bacteria=prokaryotes

•What does pro mean?

•Pro means before, therefore prokaryotes were the first cells

Just 1 percent of bacteria and archaea have been discovered!

Eubacteria and archaebacteria

Eubacteria and archaebacteria

Eubacteria and archaebacteria

Two groups of bacteria: Eubacteria (bacteria) and archaebacteria

Eubacteria and archaebacteria

Eubacteria live everywhere

and

Archaebacteria live in extreme environments◦ex: hot springs, acidic environments, saline (salt) environments

Eubacteria and archaebacteria

Important functions of bacteria include:

They do photosynthesis. Ex: cyanobacteria

Eubacteria and archaebacteria

Important functions of bacteria include:

Some do cellular respiration

Eubacteria and archaebacteriaBacteria reproduce asexually

EubacteriaArchaebacteria

• Asexual reproduction

• Does cellular respiration

• Heterotrophs• Makes methane • Lives in extreme

environments • Unicellular

• Asexual Reproduction• Some do cellular

respiration• Some do photosynthesis • Heterotroph or Autotroph• Lives everywhere• Unicellular

Prokaryote

Extremophile

Vocabulary

Archaebacteria & Eubacteria Species Investigation• On a notebook sheet of paper, write down your prediction of whether or

not the organism is eubacteria or an archaebacterial cell based on the

description provided.

Heterotroph vs Autotroph

Archaebacteria or Eubacteria

Name: Cyanobacteria

Description: Carries out photosynthesis, and is able to reproduce asexually, contains DNA, and is found in almost every terrestrial and aquatic habitat.
