Fungi are - Heterotrophs that feed by absorption
How many species of fungi have been described - about 100,000 species of fungi have been described
How many species of fungi are estimated to exist - 1.5 million species of fungi
Fungi share which key traits - the way in which they derive nutrition
Fungi use enzymes to - break down a large variety of complex molecules into smaller organic
compounds
The versatility of these enzymes contributes to - fungi's ecological success
Fungi exhibit diverse lifestyles, name them - -Decomposers
-Parasites
-Mutualists
The most common Body Structure - multicellular filaments and single cells (yeasts)
-Some species grow as either filaments or yeasts; others grow as both (dimorphic fungi)
Yeast is - term for a unicellular fungus
The morphology of multicellular fungi enhances - their ability to absorb nutrients
Fungi consist of - mycelia (mass of hyphae), networks of branched hyphae (hypha - singular) adapted for
absorption
, Fungal cell walls contain - chitin
Most fungi have hyphae divided into cells by - septa, with pores allowing cell-to-cell movement of
organelles
Coenocytic fungi lack - septa and have a continuous cytoplasmic mass with hundreds or thousands of
nuclei
Some unique fungi (Mycorrhizal Fungi) have specialized hyphae called - haustoria that allow them to
penetrate the tissues of their host
Mycorrhizae are - -mutually beneficial relationships between fungi and plant roots
-deliver phosphate ions and minerals to plants
-Most vascular plants have mycorrhizae
-colonize soils by the dispersal of haploid cells called spores
Ectomycorrhizal fungi - form sheaths of hyphae over a root and also grow into the extracellular spaces of
the root cortex
Arbuscular mycorrhizal fungi - extend hyphae through the cell walls of root cells and into tubes formed
by invagination of the root cell membrane
Fungi propagate themselves by - producing vast numbers of spores, either sexually or asexually (or both)
Fungal nuclei are normally - haploid, with the exception of transient diploid stages formed during the
sexual life cycles
Sexual reproduction requires the fusion of - hyphae from different mating types
Fungi use sexual signaling molecules called - pheromones to communicate their mating type
