How can you tell the difference between moss and lichen?

lichens are usually found on rocks, and moss grows on the ground where it is damp and there is dead things around for it to eat...moss looks like a plant, and lichens look like a rock bumple...

Most animals don’t eat moss. It’s hard to digest, and it has little nutritional value. But reindeer fill up with lots of moss. Why? The moss contains a special chemical that helps reindeer keep their body fluids warm. When the reindeer make their yearly journey across the icy Arctic region, the chemical keeps them from freezing—much as antifreeze keeps a car from freezing up in winter.

Moss needs lots of moisture and little direct sunlight.  The soil needs to be relatively low in iron.

Hi there!  I hope I can help...\n1) c\n2) b (lichens are made up of fungi & algae that live together & mutually help each other - algae makes food through photosynthesis while the fungi helps retain water & minerals).\n3) See what you make make of this: http://en.wikipedia.org/wiki/Biophilia\n4) b (visually compare scales to feathers - claws don't cover an animals body)\nI don't know the answers to the other two, but I am very sure of the above answers.

The two parts that you have mentioned belong to same leaf but not necessarily identical in function and face different environmental factors.\n\n1)The upper surface of a typical leaf-:\n\nThis part receives direct sunlight and does more photosynthesis so it has more chloroplasts and it is darker green as compared to the other side.\nIt has water proof coating of wax or cuticle and less hair hence it is more smooth and shining.\n\n2)Lower surface  of a typical leaf-: \n\n This part is away from the direct sun light and has less chloroplast so pale green in color. It is more concerned with gaseous exchange. It has less waterproofing hence not so shiny.It has more hairy outgrowth to maintain humidity around stomata, so rough in texture.

do you mean lichens? if so, D would be correct.

The term epiphyte refers to any plant that grows upon or attached to another living plant. The term stems from the Greek epi- (meaning 'upon') and phyton (meaning 'plant'). These plants are sometimes called "air plants" because they do not root in soil. However, there are many aquatic species of algae, including seaweeds, that are epiphytes on other aquatic plants (seaweeds or aquatic angiosperms).\n\nOf course there are also parasitic and semiparasitic plants growing on others. The best-known of this is the mistletoe.\n\nAn epiphyte uses photosynthesis for energy and (where non-aquatic) obtains moisture from the air or from dampness (rain and cloud moisture) on the surface of its host.\n\nRoots may develop primarily for attachment, and specialized structures (for example, cups and scales) used to collect or hold moisture.\n\nEpiphytes are not parasitic on their host, growing independently and deriving only physical support. A clear advantage is gained over other herbs restricted to the ground (soil) surface where light is less available in the forest and herbivores are more active. However, epiphytes may grow so thickly as to damage the supporting plant.\n\nThe best-known epiphytes include mosses, lichens, orchids, and bromeliads (such as Spanish moss of the genus Tillandsia), but epiphytes may be found in every major group of the plant kingdom. Assemblages of large epiphytes occur most abundantly in moist tropical forests, but mosses and lichens occur as epiphytes in almost any environment with trees.

The name of the moss which is the Bryophyte, is Polytrichum.Which is a gametophyte.It occurs in the moist coniferous forests; widespread across Northwestern Ontario and boreal forests; cosmopolitan.It is a dark green, robust, unbranched, 4 - 15 cm tall or more; single-sexed, males have enlarged heads at plant tips, females produce sporophytes; lower portion covered by grey rhizoids. Leaves - 6 - 10 mm long, lance-shaped, sharply pointed; spread at right angles when moist, erect-flattened and rolled when dry; membranous, sheathing base; edges coarsely toothed; midrib covered on inner surface with 20 - 55 vertical tiers of cells (lamellae) 4 - 9 cells high, each tier ends with U-shaped cell.The sporophytes - common, at plant tips; stalk wiry, very long; capsules horizontal, 4- sided, 64 short, rounded teeth and expanded central membrane around capsule mouth; capsule hood has tuft of hair at tip, covers entire capsule.\n\n The hair-caps are the largest unbranched mosses in western Canada. Common hair-cap could be mistaken for alpine hair-cap (Pogonatum alpinum, also called Polytrichastrum alpinum), but that moss has round (not square) capsules. Tea made from common hair-cap was once taken to dissolve kidney and gall bladder stones. Based on the Doctrine of Signatures, this moss should be good for the hair, so a strong tea of common hair-cap was used as a rinse to 'strengthen and beautify' ladies' tresses. *The stems of common hair-cap often reach 30 - 45 cm or more in length. when the leaves are removed, the central stems form tough, pliable strands that have been used to make brooms and brushes or have been woven or plaited to make mats, rugs, baskets, and hassocks. Apparently this was quite an art in ancient Europe. A hair-cap moss basket from the remains of an early Roman fort at Newstead, England, dates from 86 AD.

on a tree...have a look if there are some silver white or green patches (not moss) and scrape some off....there are lots of lichens about if you know where to look

Yes, lichens are used as a bio-indicator for atmospheric sulphur dioxide:\nI quote:\n"Lichens are widely used as environmental indicators or bio-indicators. If air is very badly polluted with sulphur dioxide there may be no lichens present, just green algae may be found. If the air is clean, shrubby, hairy and leafy lichens become abundant. A few lichen species can tolerate quite high levels of pollution and are commonly found on pavements, walls and tree bark in urban areas. The most sensitive lichens are shrubby and leafy while the most tolerant lichens are all crusty in appearance. Since industrialisation many of the shrubby and leafy lichens such as Ramalina, Usnea and Lobaria species have very limited ranges, often being confined to the parts of Britain with the purest air such as northern and western Scotland and Devon and Cornwall."\n\nThey're also edible, but having tried them I can report that they are not especially tasty!!!!

They are part of the FBI. Fungas bactiria and invertabrates. The decomposers. Without these supper heros we'd be neck deep in death! Also some fungi have a nitrogen fixxing quality meaning that plants that require high nitrogen in their soil will be pron to living in an area with these fungi. And without fugi we'd have no lichen. Fungi and alge form a sybiotic relationship. The fungi breaks down one organic, and the alge photosynthisizes returning energy in that form. Lichen and mosses are responsable for the reforestation of north america ( or any land that was stipped of life) after the last ice age. Their called primary sucessors. Hope that helps!

two distinct forms have to be different species... don't really get what you're asking but hope that helps...

that's only true in the northern hemisphere. it's because moss likes shade, and the north side of anything in the northern hemisphere is the shady side

Check for the optimum texture and pH for the grass.\n\n\nFor the amoeba,i guess it is contractile vacuole.

Most likely it's Lichen Planus. type it into the search box, and you should get the translation
