Term | Definition |
---|---|
algae (singular alga) | The group of protists characterized by chloroplasts, photosynthesis and a cell wall. Also called the "plant-like" protists. |
amoeboid movement | The process of alternating the areas of the cell membrane that bulge in and out, forming pseudopods and causing amoebas to move about in their environments. |
cap | The top of a mushroom. |
chitin | The carbohydrate that makes up the cell walls of Fungi. |
colony | Hundreds or more single cell organisms massed together in the same area often appearing as one single organism but each cell functions independently. |
conjugation | The form of sexual reproduction that paramecium perform. |
filament | A long "string" of algae cells that are connected to one another end to end. |
fragmentation | A type of asexual reproduction in which filaments break into two or more smaller filaments and continue to reproduce by mitosis. |
germination | The process of a seed or spore sprouting and growing into a new organism. |
gills | The slits in the underside of a mushroom, where spores are produced. |
hyphus | The basic cell that all Fungi are made up of. |
lichens | A symbiotic relationship between a species of Fungi and a species of algae. |
mycelia | The physical structure of a fungus is called a mycelia (rather than a "plant"). |
plankton | The layer of small and microscopic organisms living in the sea and fresh water. |
protists | Single cell and "simple" multi-cellular eukaryotic organisms. |
protozoa (singular protozoan) | The group of protists characterized by no cell walls and no chloroplasts that have to ingest other organisms to obtain their energy. Also called the "animal-like" protists. |
saprophytes | The name for decomposers, meaning they obtain their nutrients by eating dead organic material. |
slime molds | The group of protists characterized by obtaining their nutrition by decomposing dead organisms. Also called the "fungus-like" protists. |
sporangia | The asexual reproductive structures of Fungi. |
spore | The single-cell structure used by Fungi to reproduce asexually. |
stalk | The "stem" of a mushroom. |
stolons | Mold hyphae that run along the surface of the bread. |
symbiotic | A relationship in which two organisms live closely together, and each organism benefits from the presence of the other. |
yeasts | Unicellular Fungi which live in moist environments. |
