| Question | Answer |
|---|---|
| protozoan | single cell protists with animal-like behavior |
| algae | photosynthetic, plantlike, autotrophic protists. |
| pseudopodia | are temporary cytoplasm-filled projections of the cell wall that certain eukaryotic cells use for motion or for ingesting nutrients. |
| asexual reproduction | is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only, it is reproduction which does not involve fertilization. |
| flagellate | are organisms with one or more whip-like organelles |
| ciliate | are a group of protozoans characterized by the presence of hair-like cilia |
| sporozoan | Any of numerous parasitic protozoans of the class Sporozoa, most of which reproduce sexually and asexually in alternate generations by means of spores. |
| spore | is a reproductive structure that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions. Spores are usually haploid and unicellular and are produced by meiosis in the sporangium by the sporophyte. |
| oral groove | A depression leading to the mouth in some invertebrates. |
| gullet | An invagination into the cytoplasm of certain ciliates, used for food intake. |
| malaria | is a mosquito-borne infectious disease of humans caused by eukaryotic protists of the genus Plasmodium. |
| plasmodium vivax | is a protozoal parasite and a human pathogen. The most frequent and widely distributed cause of recurring malaria. |
| pellicle | a thin layer supporting the cell membrane in various protozoa. |
| diatom | are a major group of algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons. |
| silica | A white or colorless crystalline compound, SiO2. |
| red tide | algal bloom; an event in which estuarine, marine, or fresh water al gae accumulate rapidly in the water column and results in discoloration of the surface water. |
| thallus | meaning a green shoot or twig, is the undifferentiated vegetative tissue of some organisms in diverse groups such as algae, fungus, some liverworts, lichens, and the Myxogastria. |
| colony | several individual organisms of the same species living closely together, usually for mutual benefit. |
| alternation of generation | in the life cycle of plants, a multicellular diploid sporophyte, alternates with a multicellular haploid gametophyte. |
| sporophyte | in algae and plants, the diploid form of an organism in alternation of generations that produces spores. |
| gametophyte | is the haploid form of an organism in alternation of generations that produces male or female gametes. |
| slime mold | is a broad term describing protists that use spores to reproduce. Part of some of these organisms' life cycles can appear as gelatinous "slime". |
| eye spot | a photoreceptive organelle found in the flagellate (motile) cells unicellular photosynthetic organisms. |
| contractile vacuole | is an organelle involved in osmoregulation. It is found predominantly in protists and in unicellular algae. |
| cytoplasmic streaming | is the directed flow of cytosol and organelles around large fungal and plant cells. This movement aids in the delivery of nutrients, metabolites, genetic information to all parts of the cell. |
