Fungi Flashcards
Fungi are essential for the well-being of most terrestrial ecosystems because
they break down organic material and recycle vital nutrients
Fungi are _____ trophs
Heterotrophs
Fungi use _______ to break down a large variety of complex molecules into smaller organic compounds.
enzymes
2 most common body structures of Fungi
Multicellular filaments and single cells (yeast)
Known as the intermediary between plants and animals
Fungi
Diverse lifestyes of Fungi
Decomposers/saphrophytes, parasites, mutualists
Morphology of multicellular fungi enhances ability to
absorb nutrients
Networks of branched hyphae
Mycelia
What are mycelia adapted for
absorption
Fungi cell walls are made of _____
Chitin
thread-like filaments that make up body of fungi
hyphae
Fungi that have hyphae divided into cells/walls by septa
Septate fungi
Fungi that lack septa
Coenocytic fungi
Penetrate tissues of host/ cause diseases
Haustoria
Mutually beneficial symbiotic relationships between fungi and plant roots
Mycorrhizae
Reproduction used by Fungi
asexual and sexual
Sexual signaling molecules used by Fungi to communicate mating type
Pheromones
union of two parent hyphae
Plasmogamy
Mycelium where haploid nuclei of each parent fungus coexist before fusing
heterokaryon
Haploid nuclei of parent fungi pair off 2 to a cell
Dikaryotic
Haploid nuclei fuse, produce diploid cells
Karyogamy
Produce haploid spores by mitosis, form visible mycelia
Molds
Yeasts reproduce ________
asexually
Reproduce asexually by budding
yeasts
Mold that decomposes food
Penicillum
common yeast
Saccharomyces cervisiae
