Organism that consists of a symbiotic joining of a species of fungi and a species of algae
A symbiotic partnership between a fungus with an algae and/or a cyanobacteria; lichens are often described as "organisms" when in fact they are a community of 2 or 3 species Some lichens live on rocks, where they appear as paintspots, whereas others are fibrous and drape from trees or form dense ground cover Several of the fibrous species are staples in the diet of caribou
- A composite plant comprised of an ALGA and a FUNGUS growing together in an intimate association Lichens are often found in patches on tree trunks, bare ground , rocks and walls They can be sensitive INDICATORS of POLLUTION
any thallophytic plant of the division Lichenes; occur as crusty patches or bushy growths on tree trunks or rocks or bare ground etc
the common name for any member of the group Lichenes, occurring as fungal and algae cells in symbiotic union and growing in various forms of rocks or trees (Morris 1992)
Any of various small plants composed of a particular fungus and a particular algae growing in an intimate symbiotic association and forming a dual plant, commonly adhering in colored patches of sponge-like branches to rock, wood, soil, etc
to one characterized by the eruption of small, conical or flat, reddish pimples, which, if unchecked, tend to spread and produce great and even fatal exhaustion
a composite plant made up of a fungus and an algae usually black, but can be gray or orange; grows slowly, often on boulders the oldest plants in the mountains - some dating back 11,000 years lichen covered boulders can be extremely slippery when wet
The species are very widely distributed, and form irregular spots or patches, usually of a greenish or yellowish color, upon rocks, trees, and various bodies, to which they adhere with great tenacity
Plant-like colonies of fungi and algae that grow on the exposed surface of rocks Lichen grow at a constant rate within a single geographic area
Natural material that grows on rocks Resembles scaled-down trees and bushes and is used as a scenery material
this "plant" consists of two different types of living things that live together, each benefiting the other One is algae, a small one-celled plant that can make use of energy from the sun The other is a fungus that takes nutrients from the air, rocks or other plants for the algae to use
a descriptive term for the white, lace-like lesions that occur on the skin or mucous membrane; the cysts resemble lichen that grows on trees
a forest growth that resembles scaled-down trees and bushes and is used as a scenery material
n: A symbiotic relationship between a fungus and a moss The moss does most of the work, producing sugars for the lichen's collective metabolic pathways Lichen are generally low-growing, vary in color from bright orange or yellow to gray or black, and are often found growing on rocks and tree bark An easy mnemonic to assist recall of the nature of a lichen's symbiosis is: "A fungus took a likin' to a moss, and now they live together "
Organisms made up of algae living in the threads of a fungus The algal cells benefit from the protection and water-retaining properties of the fungus; the fungus benefits from being able to share the food made by the photosynthesising algal cells
Any of numerous complex plants growing in symbiotic association (a mutually beneficial relationship) on a solid surface such as a rock
One of a class of cellular, flowerless plants, (technically called Lichenes), having no distinction of leaf and stem, usually of scaly, expanded, frond-like forms, but sometimes erect or pendulous and variously branched
A composite plant consisting of an algae and a fungus living together in a mutually beneficial relationship
any of several eruptive skin diseases characterized by hard thick lesions grouped together and resembling lichens growing on rocks
1 a composite organism consisting of a fungus (the mycobiont) and an alga and/or a cyanobacteria (the phycobiont) that live in a symbiotic relationship As cited in
A natural plant material (comprised of algae and fungi) that are dried and painted for use in miniature landscapes Available in all hobby stores
Lichen is a group of tiny plants that looks like moss and grows on the surface of things such as rocks, trees, and walls. a grey, green, or yellow plant that spreads over the surface of stones and trees moss (leichen). Any of about 15,000 species of small, colourful, scaly plants that consist of a symbiotic association of algae (usually green) and fungi (see fungus). These extremely hardy, slow growers often are pioneer species in sparse environments such as mountaintops and the far North. Fungal cells, anchored to the substrate with hairlike growths (rhizines), form the base. In the body (thallus), numerous algal cells are distributed among fewer fungal cells. Through photosynthesis the algal cells provide simple sugars and vitamins for both partners in this symbiotic association. The fungal cells protect the algal cells from environmental extremes. Lichens may form a thin, crustlike, tightly bound covering over their substrate (e.g., cracks in rocks), or they may be small and leafy, with loose attachments to the substrate. Their colours range from brown to bright orange or yellow. In far northern Europe and Asia, lichens provide two-thirds of caribou and reindeer food. They have been the source of medicines and dyes
any of several Old World semi-crustaceous or shrubby lecanoras that roll up and are blown about over African and Arabian deserts and used as food by people and animals
