Believed to be sister group to animals because like animals they are
Heterotrophs and contain plate like cristae in mitochondria and have
flagellated cells that propel themselves with a single posterior flagellum.
Fungi form monophyletic group
Require moister to grow
They are decomposers that obtain nutrients from dead organic matter
eukaryotes. Cells contain membrane-enclosed nuclei,
Like animals fungi are
Heterotrophs; they depend on preformed carbon
molecules produced by other organisms. However, unlike animals, fungi
perform digestion outside the body, and after the food is broken down, the
fungi absorbs the predigested food.
Fungi have cell walls composed of complex carbohydrates, including
chitin: a polymer that consists of subunits of nitrogen-containing sugar.
Chitin is resistant to breakdown by most microorganisms, also the
component of the external skeletons of insects and arthropods.
DO NOT have plastids even though they may be green.
Two main types of fungi are
Simplest fungi which are
They are widely distributed in soil, leaves, fruits, and cured meats.
Important in making bread and in medicine.
Most fungi are molds: the vegetative body plan of molds consists of long,
branched, threadlike filaments called
hyphae. Hyphae are an adaptation to the
fungal mode of nutrition. Also, growth occurs at the tips of the hyphae; as the
hyphae elongate, the fungus grows into and infiltrates food sources. As hyphae
grow, they form a tangled mass or tissue-like aggregation known as a
(cobweb-like). Usually, hyphae are divided by cross walls, called
individual cells containing one or more nuclei. Some fungi, called
fungi, lack septa, and as a result, coenocytic fungus is on elongated,
multinucleated, giant cell (worm-like).
Most fungi reproduce by means of making spores, which are dispersed by wind.
