The parts of the mushroom are the cap, gills or pores, spores, stem, ring, volva, mycelium and hypha. The mushroom can be divided into underground and aboveground sections.Continue Reading
The cap of the mushroom is the topmost part. It can be conical, flat or spherical and have a variety of textures depending on the type of mushroom and stage of development. Its function is to protect the gills, which are found on the underside of the cap and composed of thin, paper-like layers stacked side by side. Some mushrooms have pores instead of gills. These are tiny tubes packed tightly together that resemble a sponge. The gills and pores produce spores, the reproducing element of the mushroom.
The stem of the mushroom supports the cap and may not be present in certain types. The ring of the mushroom is found on the upper portion of the stem and is a remnant of a protective covering for the gills that ruptured as the cap grew. At the base of the stem is a similar remnant covering that once protected the entire mushroom. The underground portion of the mushroom is the mycelium. At its very bottom, it has hypha, which are root-like white filaments that collect water and organic matter for the mushroom.Learn more about Biology
A person can identify wild mushrooms by examining their caps, stems, gills and spores. He can also take note of the area, condition and characteristics in which the mushrooms grow, according to the Missouri Department of Conservation. Before eating any wild mushroom, it is important to make a positive identification to ensure it is edible. If a 100-percent positive identification is not possible, do not eat the wild mushroom.Full Answer >
Fish require oxygen for survival just like other animals, but they filter it from water using specialized organs called gills. A fish draws in oxygen-rich water and passes it through its gills. The organs absorb the oxygen from the water, carrying it into the fish's bloodstream for use by its organs.Full Answer >
Meiosis produces spores in plants, according to Kimball's Biology Pages. Spores are the beginning of the gametophyte generation, which produces gametes via mitosis as the starting cells are already haploid.Full Answer >
Clostridium perfringens is a rod-shaped anaerobic bacteria with the ability to form spores, according to Todar's Online Textbook of Bacteriology. It is widely found in soil, sediments and the intestinal tracts of humans and animals. Certain strains may cause food poisoning, fatal intestinal infections and gas gangrene.Full Answer >
