What is the name of a large and diverse group of organisms with eukaryotic cells that are not a plant, animal, or fungus?
Protist
What do you call the system of naming and categorizing organisms into groups?
Classification
What are tiny organisms with similarities to animals, but having only one cell?
Protozoa
What is a flagella?
A whiplike filament extending from certain simple cells, used mainly for locomotion or movement.
What are pseudopods?
Structures that amoebas use to move and eat.
What are cilia?
Short hairlike projections that beat in unison to provide a means of locomotion to protists.
What do you call a protist that is a parasite and an animal-like protist. Despite its name, it is not a fungus-like protist?
Sporozoans
What do you call the feeding relationships within an ecosystem, where smaller organisms are eaten by larger ones found in higher trophic levels?
Food chain
What do you call plantlike protists that mainly live in the water and are similar to plants in that they make their own food through photosynthesis, but differ from them in that they have no true leaves, roots, or stems?
Algae
What do you call unicellular algae, which are among the most abundant and beautiful organisms on earth due to patterns etched into their silicon-rich cell walls?
Diatoms
What is Red tide and algal bloom?
An explosion of dinoflagellate growth that causes a discoloration of the water and can be harmful to the environment.
What are the three types of algae?
Red, brown, and green
How are protist beneficial to the environment?
Protist consume harmful bacteria, are the base of the food chain in the ocean, produce oxygen, and break down decaying matter.
What are the three ways protist move?
1. Using hairlike structures (cillia) that move in unison
2. By way of flagella that rotate fast
3. Through pseudopods
How do we know that fungus-like protist are intelligent?
Fungus-like protists have the ability to:
1. find the shortest way through a maze
2. can find the shortest route between cities on a map
3. will communicate with each other when food
is scarce
4. combine to work together to ensure the survival of future generations.
