Sharing is Caring
So Simple It's Complex
100
These big pink blobs were tough to find but when they did, they took up the entire slide!
What are amoeba?
100
It is this property which separates most protazoa from algae and determines why we classify them thus.
What is locomotion (the ability to move)?
100
Since most algae produce their own food, we classify them as this type of feeder.
What is an autotroph?
100
Two or more species working in close relationship forms this kind of bond.
What is symbiotic?
100
Protista vary widely in their complexity. It is here that we find our first and most basic form of this kind of reproduction.
What is sexual reproduction?
200
These "grass of the sea" microbes were looked like green tubes in a line.
What are algae (spyrogyra)?
200
Amoeba may look like ugly oozes (and they are!) but they're actually like two oozes, the outer ectoplasm and the inner endoplasm which they push out to form these "feet".
What are pseudopods?
200
The body of plant-like organisms which do not have leaves, roots or stems are given this special name.
What is a thallus?
200
Algae and fungi working to eat away at the surface of a rock is an example of this kind of relationship.
What is mutualism?
200
Though found on very simple creatures, this ambulatory organelle is so complex it is found nowhere else in nature but at the cellular level.
What is the flagellum?
300
These organisms use silicon dioxide in their cell walls, a compound which grants them crystalline, geometric shapes.
What are diatoms?
300
Genus 'plasmodium' is home to deadly protists capable of releasing these seed-like structures which can reproduce exponentially in a host.
What are spores?
300
Though kelp may look like a plant, it actually comprises a sessile colony of cells which anchor to the sea floor using these special organelles.
What is a holdfast?
300
Malaria is a disease caused by this sort of relationship between sporazoa and humans.
What is parasitism?
300
During this odd from of conjugation, paramecium can be seen passing this organelle from one to another, merging DNA and splitting themselves into two cells.
What is the micronucleus?
400
Though most organelles were too small to see, these structures (normally responsible for keeping stable pressure or holding food in the cell) were numerous and easy to spot.
What are vacuoles?
400
Euglena (of the Phylum "Mastigophora") possess this green pigment, not unlike plants which also use it for photosynthesis.
What is chlorophyll?
400
You can thank algae for producing this chemical which is used to thicken many syrups and pastes we eat.
What is algin?
400
In many Texas pastures you'll find birds snacking on the insects stirred up by longhorns and mustangs, a perfect example of this sort of relationship.
What is commensalism?
400
Algae possess many plant-like qualities including this substance, seen its own most basic form, which makes up their cell walls.
What is cellulose?
500
Some microscopes help resolve focus by lowering the lens closer to the slide, but others bring this large component of the microscope *up* toward the lens.
What is the stage?
500
Paramecium belong to this phylum, so named for the hair-like structures surrounding their cell wall used in locomotion.
What is ciliophora?
500
Biblical plagues and war-torn shores notwithstanding, what we call "red tides" are atually the result of these remarkable organisms of the Phylum Pyroophyta.
What are dinoflagellates?
500
Certain protazoa will inhabit the space between plant cells and intercept nutrition passing between the cells but increase the structural stability of the overall plant in this type of relationship.
What is parasitism? (Though the presence of the protazoa benefits the plant in one way, it ultimately requires the plant for sustenance.)
500
The most basic form of multicellular organism (except for your biology teacher) belongs to this Phylum, home to brown algae, rockweed, and kelp.
What is Phaeophyta?
