Warm-Up

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

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!

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

Bacteria Research ProjectDay 1 – Research◦ Answer all the questions on your research handout for your assigned bacteria.

Day 2 – Project ◦ Put all the information from your research from the previous day on a poster

in a creative and colorful way.

◦ Presentations

Closure A new type of cell is discovered. Explain how you would know if it is archaebacteriaor eubacteria.
