What is true of all true fungi? |
|
Definition
All true fungi are filamentous or unicellular heterotrophs, most of which absorb their food in solution through cell walls. |

How does phylum Chytridiomycota reproduce? |
|
Definition
Many reproduce only asexually through the production of zoospores within a spherical cell.
Sexual reproduction by fusion of haploid gametes |

What is true of Zygomycota Hyphae? |
|
Definition
Numerous haploid nuclei, with no cell walls between them |
|
|
Term
How do Zygomycota reproduce asexually? |
|
Definition
Asexually- Sporangiophores grow upright and produce sporangia at the tips, forming black spores. |
|
|
Term
How do Zygomycota reproduce sexually? |
|
Definition
Progmentangia on hyphae of different mating strains become gametangia. These gametangia merge and multinucleate zygote when nuclei of two strains fuse in pairs. Thick wall forms around = zygosporangium containing numerous diploid nuclei.Meiosis forms spores in sporangia on sporangiophores. I think these are made up words. |

How does phylum Ascomycota reproduce asexually? |
|
Definition
Single or chains of conidia produced at the tips of hyphae called conidiophores, or budding in yeasts |
|
|
Term
How do Ascomycota reproduce sexually? |
|
Definition
Antheridium (male) and ascogonium (female) from two hyphae connect. •Male nuclei migrate into ascogonium where nuclei pair, but do not unite. •Hyphae, whose cells contain one male and one female nucleus, grow from ascogonium. •Ascoma forms, with sacs called asci (singular: ascus). –The two nuclei in each ascus unite to form zygotes that undergo meiosis. –Resulting cells divide by mitosis forming a row of eight ascospores in each ascus. |

What is true of Basidiomycota Hyphae? |
|
Definition
It is divided into individual cells |
|
|
Term
How do Basidiomycota reproduce? |
|
Definition
Mostly sexual- Hyphae of individual mating types unite and initiate a new mycelium, called dikaryotic hyphae through the process of plasmogamy, in which each cell has one nucleus from each original mating type. |

What is the realtionship between fungus and algae in lichen? |
|
Definition
–Photosynthetic component supplies food. –Fungus protects the photosynthetic organism from harmful light intensities, and absorbs and retains water and minerals. •Three genera of green algae and one genus of cyanobacterium involved in 90% of all lichen species. •Each lichen has own unique species of fungus, usually a sac fungus. •Lichen species are identified according to their fungus. |
