What is bacteria?

Bacteria are:
The smallest cells known.
Have a cell wall
Form spores
have no nuclear membrane
may have flagella
their shapes are bacilli, cocci and spirilla.


What is cyanobacteria?

It has cells usually larger than bacteria
contains chlorophyll
cary on photosynthesis.
Eg. Nostoc and Gloeocapsa.


What are Protozoa?

single celled
may form colonies
free-moving (except for sporozoan)
Examples: amoeba, paramecium, euglena, malaria and plasmodium.


What are Algae?

Contain chlorophyll; may be single-celled or form colonies, e.g. spirogyra, diatoms brown or red algae volvox colony.


What are slime molds?

Naked mass of protoplasm
many nuclei
no cell membrane
form sportes
eg: physarum.


What are Fungi?

Plant-like; heterotrophic (no Chlorophyll); Cell wall composed of chitin; form spores, e.g. yeast, molds and mushrooms.


What are Hypha?

A thread-like filament that is the basic structure of a fungus.


What is mycelium?

A mass of hyphae in a fungus.


What are some of primary traits of the amoeba?

moves and feeds using pseudopodia; takes in food via phagocytosis; food digested in food vacuole; contractile vacuole eliminates water reproduces with binary fission.


What are some primary traits of the Paramecium?

Locomotion via cilia
Ingests via Oral groove
digests in gastric vacuoles
eliminates waste via anal pore
two nuclei: Micronucleus and macro-nucleus
eliminates water via the con tactile vacuole.
reproduces by conjugation.


What is phagocytosis?

The method by which the amoeba obtains food by surrounding the food particle with the cell membrane and bringing the contents into the cell as a vacuole.


What is the Anal pore?

Structure in paramecia and other protists through which wastes are eliminated.


What is the oral groove?

The part of the cell through which the paramecium ingests food.


Compare micronucleus to macronucleus.

The small (micronucleus) and the large (micronucleus) nuclei that are present in paramecia and other ciliates. The micronucleus is involved in conjugation.


What is the contractile Vacuole?

The cell structure found in some freshwater protists and other organisms, that is used to eliminate excess water.


What is the plasmodium?

A parasitic protozoan that causes malaria. Also, a stage in the life cycle of a slime mold.


What is Sporangia? Structures in which spores are produced.

Structures in which spores are produced.


What is conjugation?

The temporary joining of two unicellular organisms during which genetic material is transferred from one cell to the other. (some protists, bacteria, altar, fungi, paramecium)
