Dear Mrs. Cannon, the Netscopia page has locked me out; it no longer recognizes my email address, which, therefore, means it can no longer give me a password, or access to your page. The first part of this assignment was done with the information from your page, but the second part was scraped together from information either a) gleaned in class, or b) learnt through trial and error off various webpages. Much of this blog is defining and clarify important terms in microbiology. I though that was important, as I can't understand paragraphs written in "biologist", unless I can speak "bioligist" too. And, alas, the shift-key trick in Yearbook does not work in biology. My pictures stretch and pull all over the place.
Sincerely, Emily Z.

To begin: Wikipedia defines microbiology as:
the study of microrganisms, which are unicellular or cell-cluster microscopic organisms. This includes eukaryote such as fungi and protists, and prokaryotes, which are bacteria and archaea. Viruses, though not strictly classed as living organisms, are also studied. In short; microbiology refers to the study of life and organisms that are too small to be seen with the naked eye.
Micro, meaning small, biology, meaning life. "Small Life".

PROTISTS:
protist: a collective term for organisms (with nucleated cells) that are not considered true animals, plants, fungi; includes algae
The image shows the different types and shapes of protists. They're rather simple creatures. They're kind of set up like the plant cells we studied in science last year. Generally, protists have simple forms and basic life functions.
- algae
- amoeba
- ciliates
- flagellates
- protozoa
- water molds
- Euglena
Algae is very important for a variety of ecosystems and animal life, especially in lakes. Alage creates oxygen needed for creatures like fish. Dead algae also drift to the ocean, and support a whole other ecosystem there.
Ciliates are very important and very common. They live in a variety of water-environments. Ciliates are on the larger side for protozoa. The term ciliate comes from cilia, referring to the hair-like structure that aids in movement. Ciliates are special in the sense that they have two nuclei. They have a feathery look to them. http://en.wikipedia.org/wiki/Ciliate
What are protozoa? They're more animal-like creatures, like amoebas. Some sources even claim it is in fact a one-celled animal. Protozoa are important for the role they play as parasites, and according to one site, they are the most abundant animal in the world. http://www-biol.paisley.ac.uk/Courses/Tatner/biomedia/units/prot1.htm
What are water molds? Water molds are ALWAYS found in wet environments. Their real name is "Oomycota", which sounds like a woman who loves her new jacket. Water molds are not necessarily the friends of humans; they are the cause of the Great Potato Famine in Ireland. Water molds can also cause disease in fish. For a long time, they were considered fungi because they have phytae and feed off of rotting substances (like mulch). However, they do not have a cell wall made of chitin, and also contain a chemical found in kelps and diatoms. Water molds play an important role in decomposition because they absorb food from their surrounding environment (like dirt or water). http://www.microbeworld.org/microbes/protista/watermolds.aspx

What are Euglena? Euglena are unicellular, with cholorplast to photosynthesize. However, they can also absorb food, so they are both autotrophic and heterotrophic. Euglena use flagella for movement, and have an eyespot to detect light and dark. They cannot see with their eyespot, but they can "see" the difference between light and dark... or the top of the puddle versus the bottom... or the path to safety versus the mouth of a predator! Actually, it helps the euglena find light spots for photosynthesis. Without an eyespot, they would not be able to find sources of energy. Euglena also have a pellicle for protection.
