Fungal Characteristics 1) Cell wall made of Chitin 2) Heterotrophs and major Decomposers 3)Body is made of Long filaments of hyphae which form a mycelium 4) Reproduce sexually and asexually Asexually by spores Sexually by mating of hyphae filaments .
Note the cup shapes and orange peel colour
-are primarily decomposers
-asexual spores may be produced in sporangia
-sexual reproduction occurs between + and – strains forming a 2n zygote; a zygospore develops and may lie dormant for a long period of time; meiosis occurs just before germination
-only the zygote is diploid; all hyphae and asexual spores are haploid
The fungal mass of hyphae, known as the MYCELIUM penetrates the bread and produces the fruiting bodies on top of the stalks
Mycelia = a mass of hyphae or filaments
The zhizoids meet underground and mating occurs between hyphae of different molds (SEXUAL REPRODUCTION)
Truffles are round, warty, fungi that are irregular in shape. They vary from the size of a walnut to that of a man's fist. Since the times of the Greeks and Romans these fungi have been used in Europe as delicacies, as aphrodisiacs, and as medicines. They are among the most expensive of the world's natural foods, often commanding as much as $250 to $450 per pound.
Truffles are harvested in Europe with the aid of female pigs or truffle dogs, which are able to detect the strong smell of mature truffles underneath the surface of the ground. The female pig becomes excited when she sniffs a chemical that is similar to the male swine sex attractant. The use of dogs to find truffles is also and option.
Basidiomycete Fungi that all produce Basiospores
Rust infecting wheat leaves
Whitrot Smut digesting old wood
Rust infecting a Leaf
-Regarded as imperfect because they exhibit no sexual stage has been observed in their life cycle
-Members are not closely related and are not necessarily similar in structure or appearance; do not share a common ancestry, polyphyletic = coming from many ancestors – hmm weird
The water molds are better known as the MILDEWS. Fish tank fuzz is an example.
Protist-like mold because share common characteristics with plant-like protists, such as the cell wall
Devastated potato crops, causing devastating starvation in Ireland
Coenocytic hyphae where the nucleis of each cell is embedded in the cytoplasm without a cell wall
Eg. Zygomycota, Oomycota
Hyphae with cross walls
Eg. Basidiomycota, Ascomycota
Lichens are mutualistic symbiotic organisms. They have an ____________ fungus and a _________ or cyanobacterial portion. There are three lichen growth forms which are predominant in nature: _____________________
Mycorrhizae means “fungus-root”; mutualistic relationship between plant and fungi
The plant photosynthesizes while the fungus more efficiently takes up nutrients and water from the rhizosphere than the roots would alone.
Soredia are the asexual reproductive part of lichens, containing both symbionts. Rhizines may be present to anchor the lichen. Notice the distinctive algal layer and the fungal layer present in the above illustration.
