What is biology?
The study of life
What does an object have to do in order to be considered living?

Who developed the Scientific Classification? (Father of Modern Taxonomy)
Carolus Linnaeus
Binomial Classification System
Used to name species
What does MSDS stand for?
Material Safety Data Sheet
What is the purpose of the MSDS?
It has all of the information for possible harmful chemicals that you are more than likely to use in your lab class.
About how many years ago was the Protista Kingdom estimated to be on earth.
Estimated to live on earth about 2.5 billion years ago.
Are the organisms in the kingdom protista unicellular or multi-cellular?
They are usually single celled.
What domain does the kingdom protista lay in?
Eukaryota
Are the organisums in the protista kingdom heterotrophs or autotrophs?
They are both. Some organisms are heterotrophic, autotrophic, or both.
What is Zooplankton?
Microscopic animals in the water.
What is Phytoplankton?
Microscopic plants in the water.
What is cilia?
Short, hairlike things around a cell. Used in order to make the cell move.
What are Rhizopoda?
a broad group of protozoan amoeboid organisms placed in the kingdom Protista.
How do Amoebas move?
By the help of Pseudopod, they have no flagella or cilia.
If an organism has cilia, what is it considered /called?
Ciliophora
What is a unique thing that dinoflagellates have?
2 Flagella, and they can be bioluminescent.
What protista causes red tides?
Dinoflagella
Red tide
Toxin that makes a tide look red. Extremity toxic.
How are Red Tides made?
Overgrowth of Dinoflagellas causes “Red Tides” since the Dinoflagellates produces that tocsin.
Paralytic shellfish poisoning
Caused when bivalves (organisms with 2 hard shells ex, muscles, clams, etc.) are exposed to Dinoflagellates. It does not kill them but the tocsins are still in their bodies. Deadly when eaten.
What is special about a Zoomastigophora?
they have between 1 - 1,000 flagella
Where can Zoomastigophora be found?
- Intestinal parasites of fish and amphibians.
- Digesting protist in the gut of termites.
What does Trypanosoma (type of zoomastigophera) cause?
African Sleeping Sickness (spread by the bite of a fly). Found in the blood. 120 days untreated can be deadly.
Chaga’s Disease
Like the African sleeping sickness but in the Americas. Spread by the bite of a sand flee. It causes heart damage.
Taxonomy
The branch of science devoted to the classification and naming of organisms.
The meaning of Binomial.
Bi= two
Nominal=Name
Name all of the elements in the classification system.
Kingdom, Phylum, Class, Order, Family, Genus, Species
What is a Species?
A group of Individuals that can interbreed (Breed with a similar animal) and produce viable fertile offspring.
What Kingdoms does the Five Kingdom Approach contain.
Monera, Protista, Fungi, Plantae, Animelia
What Kingdoms does the Six Kingdom Approach contain.
Kingdom Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animelia.
