LAB 6 Flashcards
Apothecium
-an ascus-bearing structure (ascocarp) in which the hymenium is open and not covered by fungal tissue at maturity
Ascocarp
ascospore-bearing, multicellular sporocarp formed by a member of the Ascomycota
Ascospore
a spore borne IN an ascus
Ascus
a cell that is the site of meiosis and in which spores are formed
Budding
Asexual reproduction in which outgrowths form from the parent, the outgrowths are then either pinched off or they remain attached to form extensive colonies
Cleistothecium
a closed ascocarp with the asci surrounded by fungal tissue and without regularly formed openings
Conidium
an asexual, nonmotile fungal spore that develops externally and is deciduous at maturity
Perithecium
a closed ascospore with a pore at the top
Thallus
vegetative tissue that forms the body of the fungus
Yeast
Unicellular fungus that reproduces primarily by budding
Synapomorphy of Ascomycota
Ascus
Result of asexual or sexual reproduction in Ascomycota
Ascospore or conidium
During sexual reproduction, ascopores are typically produced _____ the ascus after ______, _______, ______
Within
Karyogamy, meiosis, mitosis
Generally, ______ ascospores are produced _____ one ascus
8; inside
Ascu develop within the _____
ascocarp
3 types of ascocarps (hypocrea)
Apothecium
Perithecium
Cleistothecium
Asci typically develop on the inside of the ascocarp in the ______
hymenium
Lichens are a partnership between ____ and ___
Fungi and alga or cyanobacteria
In lichens, fungi provide____
structure, protection, and a capture area for mineral nutrients
Crustose
flatted thallus forms a cruse that is firmly attached to a substrate and cannot be dislodged without damaging the structure
Foliose
somewhat leaf-like, thallus is flat, composed of lobes that are loosely attached to the substrate
Fruticose
the most 3D of the lichens, branched and resembling either miniature shrubs or hanging in strands
Types of thallus structures in lichen
Crustose, Foliose, Fruticose
