Protists, Fungi, Lichens
| Term | Definition |
|---|---|
| Protist | Single-celled eukaryotes that do not form tissues. |
| "True" Protists | Photosynthetic Protists. |
| Autotrophs | Creatures that make their own food. |
| Heterotrophs | Creatures that eat autotrophs or other heterotrophs. |
| Algae | Water-dwellers. |
| Ciliate | A creature that is motile by means of cilia. |
| Cilia | Tiny, paddle-like structures used for locomotion. |
| Flagellate | A creature that is motile by means of flagella. |
| Flagellum | Whip-like tail used for locomotion. |
| Pseudopod | "False Foot". An extension of the cell membrane and cytoplasm of a creature for locomotion. |
| Protozoan | "Animal-like" Protists. Heterotrophs. |
| Hyphae | Many-celled, thread-like tubes which make up a fungus |
| Saprophyte | A creature that eats dead and decaying things |
| Spore | A water-proof single cell that can grow into a new organism. In fungi, these cells are haploid. |
| Basidium | Means "club" |
| Basidiomycota | Club fungi |
| Ascus | Means "sac" |
| Ascomycota | Sac Fungi |
| Sporangium | A structure found on many fungi which produces spores |
| Lichen | Symbiotic mutualism between a fungus and a photosynthetic algae or bacterium |
| Mycorrhizae | Symbiotic mutualism between a fungus and a plant at the roots. |
| Plasmogamy | The joining of the cytoplasm of two cells |
| Karyogamy | The fusion of two nuclei |
| Mycelium | A mass of branching, thread-like hyphae composing the body of a fungus. |
| Chitin | A tough, semitransparent substance that is the main component of the cell walls of certain fungi. |
| Obligate | Necessary. Required for survival. |
| Facultative | Optional. Not required for survival. |
| Endo | Inside of |
| Exo | Outside of |
| Symbiosis | Close and often long-term interaction between two different biological species |
| Mutualism | Both symbionts benefit |
| Parasitism | One symbiont benefits, the other is harmed |
| Commensalism | One symbiont benefits, the other is indifferent |
| Amensalism | One symbiont is harmed or obliterated, the other is indifferent |
| Synnecrosis | Both symbionts are harmed |
| Zygosporangium | Product of sexual reproduction in the phylum Zygomycota. This structure produces haploid spores which are genetically distinct from parent cells. |
| Agaricus brunescens * | Store-bought mushrooms. A member of basidiomycota |
| Calvatia gigantea | Puffballs. Members of basidiomycota |
| Saccharomyces cerevisiae * | Baker's Yeast. A member of ascomycota |
| Morchella esculentoides | Morels. A member of ascomycota |
| Tuber uncinatum | Truffles. A member of ascomycota |
| Rhizopus stolonifer * | Bread Mold. A member of Zygomycota |
| Tinea Pedis | Causitive agent of athlete's foot. |
| Deuteromycota | A now-defunct phylum which included the "imperfect" fungi. |
