Bacteria & Protist

What are bacteria?

Bacteria are tiny living beings (microorganisms) - they are neither plants nor animals - they belong to a group all by themselves. Bacteria are tiny single-cell microorganisms, usually a few micrometers in length that normally exist

together in millions.

What are Protist (Protozoa) Protists are organisms in the kingdom Protista. These organisms are

eukaryotes, meaning they are made up of single or multiple cells which all contain a nucleus enclosed by a membrane. The protists are a diverse group of eukaryotes that cannot be classified as animals, plants, or fungi.

InstructionsLesson 43: Microbes Under View

Turn to the next blank page in your science notebook and fold it down.

Label the next page “Lesson 43: Microbes Under View”

Examine each of the following slides.

Draw, label, and color each microbe shown below on an individual page

In other words, when you have completed your assignment, you will have drawn one Trypanosoma lewisi, one Paramecium, one Amoeba proteus, and one group of Bacillus (bacteria), one group of Coccus (bacteria), and one group of Spirillum (bacteria). Each drawing will be on one page and should take up the entire page

In your notebook, copy each analysis question and write a complete answer underneath the question.

Trypanosoma lewisi (flagellate protist) Illustrate in your notebook

Paramecium (ciliated protist)

Paramecium (ciliated protist) Illustrate in your notebook

Amoeba proteus (amoebic protist) Illustrate in your notebook

Bacillus (bacteria) Illustrate in your notebook

Bacillus (bacteria) Illustrate in your notebook

Copy the following explanation of Bacillius Bacteria:

Most bacteria are classified by how they appear. The term Bacillus or Bacili in microbiology refers to the particiular shape of a bacteria. In this case, Bacillius describes the rod-like shape of this micro-organism.

Coccus (bacteria) Illustrate in your notebook

Copy the following explanation of Coccus Bacteria:

The term "coccus" in microbiology simply means "round" or "spherical" in shape. The plural of coccus is cocci. This is a very broad category that is simply intended to describe basic appearance. It does not address anything other than simple shape

Spirillum (bacteria) Illustrate in your notebook

Copy the following explanation of Spirillum.

Spirillum bacteria in microbiology refers to a bacterium with a cell body that twists like a spiral. It is the third distinct bacterial cell shape type besides coccus and bacillus cells.
