Ch 29 Flashcards
Define mycorrhizal
Fungi that live on the roots of plants
Define mycorrhizae
Fungi that live along the roots
Does plant growth suffer it mycorrhizal fungi are absent?
As far as survival no it does not suffers but they do increase plant growth
What are the four reproductive structures of fungi
- Swimming gametes and spores
- Zygosporangia
- Basidia
- Asci
Swimming gametes and spores have
Both sexually produced gametes and the asexually produced spores
These are the only known motile fungal cells
Zygosporangia
A reproductive structure that is the fusion of cells from two individuals that form a haploid hyphae
Basidia
Club fungi form basidia specialized club-like cells that form at the ends of hyphae
Asci
Sac fungi form reproductive sac like cells at the ends of hyphae each ascus produce 8 spores
Define spores
It is a single haploid cell that is able to grow into a multicellular haploid organism
Key traits linking animals and fungi
DNA sequence data
Both synthesize chitin
Flagella in chytrid spores and gametes
Both store glucose
Fungi participate in symbiosis in what 3 ways?
Mutualism
Parasitic
Commensalism
Mutualism
Relationship that benefit both species
Parasitic relationship
Where one species benefits at the expense of the other
Commensal relationship
One species benefits while the other is unaffected
Define plasmogamy
What is the fusion of the cytoplasm of two individuals That does not immediately lead to nuclear fusion but instead the genetically distinct haploid nuclei persist in the same cell
