Multicellular fungi have many hyphae (singular: hypha), which are branching filaments. Hyphae have a tubular form and are separation right into cell-like compartments by wall surfaces that are well-known as septa. These cells can have actually more than one nucleus, and also nuclei and other organelles can relocate in between them. (Tright here is some dispute over whether multicellular fungi are truly multicellular, because organelles and also cytoplasm have the right to move from one cell to the various other in a procedure dubbed cytoplasmic streaming. They are typically known as multicellular, yet they are not multicellular in the very same method as plants and also animals, which have actually enclosed cells.) A fungus’s network of hyphae is referred to as a mycelium.
You are watching: Which of the following statements about fungi is true?
Fungi are heterotrophs; they cannot make their very own food and have to obtain nutrients from organic product. To perform so, they usage their hyphae, which elongate and branch off promptly, allowing the mycelium of the fungus to conveniently rise in size. Some fungi hyphae also form root-choose threads dubbed rhizomorphs, which assist tether the fungus to the substprice that it grows on while permitting it to quickly attain even more nutrients from various other sources. Fungi are opportunists, which means that they deserve to attain nutrients from a vast range of resources and also grow in a broad variety of ecological problems. Some fungi achieve nutrients from dead organic matter; these fungi are dubbed saprobes and are decomposers, which break down and also eliminate dead organisms. Other fungi parasitize plants and are responsible for plant illness favor Dutch elm disease. However before, fungi have the right to also have symbiotic (mutually beneficial) relationships with photoman-made algae or bacteria, and also with plant roots. A symbiotic association of a fungus and an pet that photosynthesizes is called a lichen, while a plant root-and-fungus association is dubbed a mycorrhiza.

Many fungi have the right to recreate through both sexual and asex-related reproduction. Asexual reproduction occurs via the release of spores or through mycelial fragmentation, which is as soon as the mycelium separates into multiple pieces that flourish individually. In sex-related remanufacturing, sepaprice individuals fusage their hyphae together. The specific life cycle counts on the species, however mostly multicellular fungi have a haploid phase (wbelow they have one collection of chromosomes), a diploid stage, and also a dikaryotic stage wright here they have two sets of chromosomes yet the sets reprimary separate.
