| A | B |
|---|
| protozoan | unicellular, animal-like organism (of which there are four bascic types); the word in its Greek roots means "first animals" |
| Protista | kingdom to which protozoans belong |
| binary fission | because all protozoans are unicellular,, most reproduce in this simple "splitting-in-two" method |
| conjugation | some protozoans such as Paramecia can reproduce in this method which requires two parent organisms which join and share hereditary information |
| spore-formation | type or reproduction done only by the Sporozoan group of protozoans |
| sarcodines | group of protozoans that move by means of pseudopods or "false feet" |
| ciliates | group of protozoans that move by means of tiny hair-like projections |
| flagellates | group of protozoans that move by means of one or more whip-like tails |
| sporozoans | group of protozoans that have no means of movement within their own cellular bodies |
| pseudopod | flowing of cytoplasm into an area of the cell membrane which then extends into a structure that resembles a leg on the cell; Greek for this word means "false foot" |
| cilia | hair-like projections that allow certain protozoans spinning and twisting movements |
| flagella | whip-like tails on some protozoans |
| food vacuole | when two pseudopods of an ameba surround a particle of food, the food becomes trapped in a ___. |
| contractile vacuole | excess water is pumped out of protozoan cells by this cell structure |
| pellicle | semi-hard, yet flexible membrane which is the outer-most covering of a Paramecium |
| oral groove | indentation on one side of a Paramecium that is lined with cilia and catches food |
| gullet | funnel-shaped structure at the bottom of a Paramecium's oral groove that directs food into a food vacuole |
| anal pore | undigested material passes out a Paramecium through this structure |
| micronucleus | structure in a Paramecium that controls reproduction |
| macronucleus | structure in a Paramecium that controls all cellular activities except reproduction |
| parasite | organism that lives inside a host organism (all sporozoans are this type of organism) |
| chloroplasts | some flagellates are autotrophs, meaning they have many of these food-making cell structures |
| Amoeba (or Ameba) | most common type of sarcodine (moves by false feet) |
| Paramecium | most common ciliated protozoan |
| Euglena | common flagellated protozoan (is both an autotroph and a heterotroph; can make own food and can capture & eat food) |
| Plasmodium | sporozoan that causes the disease malaria in humans |
| eyespot | structure on a Euglena that can sense light |
| mosquito | the temporary host organism that carries Plasmodium before it gets into a human host |
