Definition
In the Eukaryote supergroup Unikonta, relatively close to animals- independently went from unicellular to multicellular
Most of a fungus’s mass is in long strands of haploid cytoplasm/cells known as Hyphae. A mass of hyphae is known a Mycelium. Mushrooms and similar fungal structures are the reproductive form of fungi, although they are only a small portion of an individual fungus’s mass and are usually short-lived compared to the hyphae. |

.may parasitize?
.some fungi with specialized hyphae can? |
|
Definition
-Fungal hyphae can have a septum with a central pore separating nuclei into individual cells or simply have evenly spaced nuclei with no individual cell boundary. In both cases, there aren’t a lot of boundaries for nutrient flow from cell to cell.
-Hyphae release digestive enzymes into the surrounding environment and then absorb nutrients; absorptive feeders.
-Fungal hyphae may parasitize other living organisms or decompose already dead organic matter. Some fungi with specialized hyphae can trap nematodes (tiny round worms), while many are specialized to extract carbohydrates from plant roots in exchange for donating inorganic nutrients to the plant cells (N, P, K)= mycorrhizae. |

Definition
| Live in water and make flagellated haploid spores similar to unicellular relatives of fungus, most famous for a disease that recently has been killing many of the world’s amphibians. |

Term
|
Definition
| Very resistant spores made from the zygote (cell formed from fusion of haploid cells from adjacent, unrelated hyphae). |
|
|
Term
|
Definition
| Form specialized mycorrhizal hyphae that actually grow inside plant root cells (penetrate the cell wall but not the cell membrane) to donate inorganic nutrients in exchange for sugars. |
