One example of a parasitic fungus is Ceratocystis fagacearum, a fungus that causes the disease oak wilt, which quickly kills healthy oak trees. Fungi in the genera Alternaria and Cladosporium are also parasitic, taking up residence in wheat and other grain plants and causing blackpoint disease.Know More
A parasite is an organism that lives on or in another organism, known as that parasite's host. The parasite gains nourishment from the host, but the host is either harmed by the parasite's presence or unaffected by it. There are parasitic plants, animals and fungi.
The parasitic fungus that causes oak wilt is spread from tree to tree via insects, which carry the fungal spores on their legs. Oak wilt is a serious problem in many forests and urban areas, since it spreads easily and almost always leads to defoliation and tree death within several years. Symptoms of oak wilt include the formation of large spore mats on the tree's trunk and rapid loss of discolored leaves.
Blackpoint disease can be caused by a number of parasitic fungal species. It causes black smudges to appear on the heads of wheat and other grains. Blackpoint disease occurs most often in fields that are overly moist and when levels of humidity are high.Learn more about Botany
Fungi are key to the ecosystem because they act as major decomposers, plant symbiotes and parasites. Decomposing fungi are extremely well-adapted to breaking down plant tissues, particularly wood, and return large amounts of carbon to the atmosphere by doing so. They are thus major parts of the carbon cycle.Full Answer >
Fungi are eukaryotic organisms that comprise one of the kingdoms of life. Most fungi are multicellular. As eukaryotic organisms, fungi possess cells with organelles, which are structures surrounded by membranes.Full Answer >
According to Encyclopædia Britannica, flatworms are mostly parasitic, soft-bodied invertebrates that include tape worms, flukes and planarians. Lacking circulatory, respiratory and skeletal systems, flatworms feature unsegmented bodies and spongy connective tissue that provide structure and fill the spaces between organs.Full Answer >
Fungi live in the soil, on forest floors, in water and even in plants, animals and the air. Fungi grow in virtually every area of the planet — they occupy tropical biomes as well as temperate zones. Fungi have different adaptations to suit the climates and conditions in which they live: some are more porous and suited for life in the rainforest and in marshy areas, while others have hard outer coverings, much like coral, which enables them to live on ocean floors.Full Answer >
