As far as I know it grows at the side where sunlight doesn't falls. However, you can reach best Biology tutors who can answer you in detail and much more understandable form. I tried them and found very helpful. You can get them at www.tutorskingdom.com and they will help you out for sure...!!!
I think you are referring to lichen, not "linchen." Lichens are a type of fungi that grow on rocks and even trees in different colours and shapes.
Lichen is a symbiotic relationship between a fungus and algae. The algae are the autotrophic component of this partnership. Green algae and cyanobacterium are types of algae commonly found in lichen.
lichens are called pioneer organisms because they are the first type of organisms that started to live in a certain forest or such. For example, If a volcanic island were to appear in the middle of the ocean. It is devoid of life at first. Certain organisms will land on the island either by washing up on the volcanic ash or land on it after being carried by the wind currents. One of these organisms would be a lichen. Lichens are considered pioneer because they will begin to destroy the rock and ash producing soil. They can survive because a lichen is a mutualistic relationship between a fungus and an algae. Once these lichens have done their work other organisms will appear, bacteria, algae, various grasses, etc. This is called ecological succession.
The two parts of the lichen help each other by making it so that the algal part of a lichen provides food while the phycobiont provides protection.
Protococcus prefers to grow on the side of rocks, trees and soil that are moist and shady. In the northern hemisphere, the sun shines more heavily on the southern side of objects. This makes the north side of trees more shady, which is their preferred location.
the pioneer plant stage
Lichen is formed by a partnership between fungi and algae. Lichen is a specific type of moss that grows on rocks.
Tundra
Nope. Lichen does not have roots. They are firmly attached to the surfaces where they grow by hyphae.
lichen
YES
Lichen EDIT: Lichen is not so much an example of biological weathering, as a cause. When Lichen grows on rocks it releases chemicals which dissolve the rock. This can be seen in rocks which appear to be covered in flakes of rock.
lichen
Lichen is considered to be a scavenger. They are commonly organisms that contain fungus and usually have a photosynthetic associate that they grow with.
Lichen is a type of fungi. Fungi is like a specie in the 6 kingdoms. Mushrooms are also fungi. Lichen can grow on rocks and logs.
Moss, tree moss, rock moss.
Lichen. A lichen is a producer that is actually composed of two different species, a fungus and an alga. The alga photosynthesizes, while the fungus absorbs nutrients from rocks and holds water. Together they begin to break down the rock.
