Most fungi are not mobile. They reproduce by producing spores. Some fungi are unicellular. They are also non-motile and eat organic matter. They secrete enzymes to break down carbon-containing products. Therefore, fungi do not exist in a symbiotic relationship. Which of the following statements about fungi is false? Answer: Fungi do not cause diseases. They can cause allergic reactions.
Most fungi are multicellular. They display two distinct morphological stages: the vegetative stage and the reproductive stage. In the vegetative stage, they are characterized by a tangle of slender threadlike structures called hyphae. In the reproductive stage, they produce ascospores and conidia. Fungi grow in soil, water, and on living tissues, and they are extremely diverse.
Throughout much of scientific history, fungi have been classified as plants. Based on molecular data, this classification supported the conclusion that fungi were more closely related than plants. Fungi and animals make up a clade called opisthokonta. This clade was named after their last common ancestor’s posterior flagellum, which is responsible for primitive fungal spores as well as animal sperm.
Which of the following statements about fungi is true? – Fungi reproduce in every way except _____. While plants produce gametes, fungi produce them in the gametangia. Fungi reproduce through multiplying their mycelium. However, they cannot reproduce in the same way as plants. The following statements about fungi are correct, and the other three are false.
– Fungi can reproduce both sexually and asexually. Budding and the release spores are two of the characteristics of the asexual reproductive process. When the reproductive organ is broken down into separate parts, it is called sexual reproduction. Fungi can also reproduce using plasmogamy and karyogamy. Asexual spores can also be made by removing a portion of the host cell.
The role of fungi in decomposition is key because they are sensitive to factors that can affect an ecosystem’s nutrient cycle. They are an integral part of the process of decomposition and allow for the return of nutrients to the environment. Dead organisms no longer contain the nutrients they need to survive. Fungi are also important decomposers of organic matter because they use enzymes to break down cellulose and lignin, the components of plant cell walls. The carbon content of the dead matter is released by their decomposition.
Fungal cell walls are thick and rich in complex polysaccharides. These polysaccharides give fungal cells their structural integrity. Other fungal cell wall components have high immunogenic capacities and are responsible for limiting the number of bacteria living in the environment. Their cell wall also protects against osmotic changes. Fungal cell walls also contain ergosterol, a substance that serves the same function as cholesterol in animal cell membranes. Flagella are found only in gametes of the primitive division Chytridiomycota,
Most fungi can form beneficial associations with other organisms, which makes them beneficial to both animals and plants. For example, Ophiostoma ulmi causes Dutch elm disease, which kills native species of elm trees by infecting the vascular system. Dutch elm disease is transmitted through the elm bark beetle, but is less prevalent in American elms.
