Fungi

Any of many symbiotic organisms being associations of fungi and algae.

Anatomy of fungi. A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds as well as the more familiar mushrooms. The suggested formula for fungus chitin is c 22 h 54 n 21 n. These organisms are classified as a kingdom fungi which is separate from the other eukaryotic life kingdoms of plants and animals.

Each hypha consists of one or more cells surrounded by a tubular cell wall. A reproductive particle usually a single cell released by a fungus alga. The chemical products of digestion are therefore.

A tangled mass of hyphae visible to the unaided eye is a mycelium plural mycelia. Structure and physiology of fungi. Most fungi contain complex enzymes and other chemical substances which when diffused into the host break down the complex substances available wood vegetation leather bread and so forth into simpler substances that can be used for food.

Some fungi such as honey fungus which is a parasite of woodland trees have hyphae collected together into long cables called rhizomorphs. They acquire their food by absorbing d. The filaments are called hyphae singular hypha.

A characteristic that places fungi in a different kingdom from plants bacteria and some protists is chitin in their cell walls. Molds consist of long branching filaments of cells called hyphae singular hypha. Not photosynthetic decomposers saprophytic cell walls impregnated with chitin.

For example fungi include the microscopic yeasts the molds seen on contaminated bread and the common mushrooms. The hyphae of most fungi are divided into cells by internal walls called septa singular septum. Fungi reproduce both sexually and asexually and they also have symbiotic associations with plants and bacteria.

Physiology of fungi a. Electron microscope studies reveal that chitin occurs as elongated variously oriented microfibrillar units. Fungus are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs cannot make their own food and have important roles in nutrient cycling in an ecosystem.

A mass of hyphae make up the body of a fungus which is called a mycelium plural mycelia. Similar to animals fungi are heterotrophs. Because there are so many hyphae packed together they are easily seen forming black bootlaces.

A symbiotic association between a fungus and the roots of a vascular plant. Fungi produce spores in both asexual and sexual life cycles mushrooms let out spores from their pores that are carried by the wind to meet other spores and become a new fungi yeast are unicellular and divide into new fungal cells mitosis. In the majority of fungi the wall lacks cellulose but contains a form of chitin known as the fungus cellulose which is strictly not identical with insect chitin.
