Characteristics of all fungi |
Have a cell wall. Have spores to reproduce. Grow in hot, moist areas. Do not have chlorophyll. Use hyphae to obtain food. |
|
|
Hyphae (HI fee) |
Fungi that is a mass of many celled, threadlike tubes. Break down food outside of the fungus. Fungal cells absorb digested food. |
|
|
Saprophytes |
Organisms that obtain food by absorbing dead or decaying tissues of other organisms |
|
|
Spores |
A waterproof reproductive cell that can grow into a new organism. forms asexually and new fungus is genetically identical to the original. ASEXUAL REPRODUCTION: |
|
|
SEXUAL REPRODUCTION: |
Fungus are not male or female. If two fungi are close together and join, a reproductive structure will form and meiosis will begin. The new fungi will genetically different from either parent. |
|
|
Basidium |
Club fungi: Mushroom. Spores are produced in a club shaped structure. The mushroom is the actual spore and the fungus is below the soil |
|
|
Gills |
Found under the mushroom's cap. Where spores are produced. Holds up the cap of the mushroom |
|
|
Ascus (AS kus) |
Sac fungi: molds and yeast. Spores are produced in little sac-like structure |
|
|
Budding |
Asexual reproduction of a single celled organism. Yeast: a new organism forms on the side of a parent and breaks off when develops. Genetically identical to parent |
|
|
sporangium |
Type of zygospore: fuzzy black mold (on bread and fruit) produce in a round spore case on the tips of upright hyphae. When the sporangium splits or breaks, the spores go into the air: If lands on warm, moist area they will grow |
|
|
imperfect fungi |
never reproduce sexually. Hard for scientists to classify. no evidence for life cycle. reproduce asexually by producing spores. (penicillium) |
|
|
penecillium |
Difficult to classify. imperfect fungi. used to make penicillin |
|
|
Lichen |
made from fungus and either green alga or cyanobacterium; very colorful. The two organisms have a relationship where they both benefit (mutualism). * Are a food source for many animals. * helps weather rocks. * sensitive to pollution so scientists know if pollutants are high in an area |
|
|
Mycorrhizae (mi kuh RI zee) |
Fungi that interact with plant roots. Mixture of hyphae and roots. fungus helps roots absorb nutrients from the soil better. Plant supplies the fungus with nutrients needed to grow |
