General
Are protists prokaryotic or eukaryotic organisms?
Eukaryotic Organisms
Which type of protist is autotrophic?
Plant-Like Protists
What is the theory called to describe how protists evolved?
Endosymbiotic Theory
What would happen to ecosystems without protists?
Ecosystems would collapse
What are 2 human activities that impact biodiversity of the Protista Kingdom?
Invasive Species and Disease Dynamics
Land Pollution
Water Pollution
Are protists unicellular or multicellular
BOTH
What are the 2 types of slime molds?
Cellular Slime Molds and Plasmodial Slime Molds
They don't come from a common ancestor
What percentage of Earths photosynthesis do protists contribute?
25%
How does mining contribute to land pollution?
Toxic Substances are added into the soil
What environments are protists commonly found in?
Aquatic/Moist Environements
What do protozoans consume?
Prokaryotes, Protozoans, and Organic Waste
Why are fossils very difficult to study protists from?
Protist fossils are too rare and scattered across the Earth
Nutrient Cycling (carbon, nitrogen, etc.)
What protists are we increasing contact with as human-caused habitat destruction increases?
Parasitic Protists
Where is the nucleic acid inside a protist
Membrane Bound Nucleus
What are temporary extensions of the cytoplasm in Cercozoans called?
Pseudopods
How do endosymbionts and host cell benefit from their symbiotic relationship?
Endosymbionts gains a home and nutrients
Host cell gains energy
Carrageen, extracted from Red Algae
How do many protists from algae blooms die?
Bacteria uses oxygen to decompose the algae blooms
What is 1 asexual reproductive strategies do protists use, explain it
Binary Fission: 1 cell splits into 2 identical cells
Multiple Fission: Nucleus divides multiple times before cell splits into multiple offspring
Budding: New organisms grow from parent and detaches
Explain how fungi-like protists feed
They secrete enzymes onto their food to break it down, then absorb the nutrients
How old are Rhodophytes (red algae)
1.9 billion years old
How do scientists figure out how diseases like cancer developed?
Understand how cells communicate by analyzing slime molds
What can be done to prevent human activities from negatively impacting biodiversity of the Protista Kingdom?
ANY GOOD ANSWER WILL BE ACCEPTED
