Yes ! forest plants with certain integer is actually one or two host trees
I can not remember the names of the plants in question . I think that mangroves are well and possibly figs do . And there are a few more.
Avatar represents roots of plants to exchange information quickly enough and in sufficient quantities to form a sort of planetary brain . * That * does not happen on Earth . Plant roots are connected , however , in a variety of ways.
First, some plants are clonal . This means that what you see from the surface , like an entire forest can become a tree . A major individual agencies in the world is an aspen ( Populus tremuloides ) called Pando , which covers about 43 hectares , with 47,000 tree trunks. All trunks spring from a single root system . It is the heaviest , and some argue the oldest organism on earth . Aspens are not the only species that can do either: sumac different ( . Rhus spp ) , sassafras ( Sassafras albidum ) and black locust ( Robinia pseudoacacia ) , among others , also form clonal colonies root suckers .
Two species , many (if not most) of the plants depend on what are called mycorrhizae associations . This is a form of symbiosis between the roots of the plants and certain fungi living in the soil. The fine threads of fungus infects - colonize - the outer layers of the root, but the plant is not injured : instead, the fungus improves plant uptake of different soil nutrients , and the plant feeds the fungus with sugars photosynthesis. Both sides benefit . Sometimes , the threads of mycorrhizae actually be connected root systems of adjacent plants , potentially linking nutrient absorption trees. "
Third, many plant species
I have not seen Avatar , so do not know the scenario , however , the roots of plants interconnecting at least two ways :
1. When forest trees , such as aspen are attacked by , for example , caterpillars , other trees of the same species living close begin to accumulate chemicals in their leaves to make it unpleasant for the caterpillars . There is accumulating evidence that attacked trees send a
No they do not to the extent that the movie AVATAR showed. I thought that was cool though. It has been know that some varieties of trees and other plants if planted near each other will grow roots toward each other and connect. Forming one large network, sharing nutrients and such. Also plant roots can form symbiotic relationships with fungi and/or bacteria. The fungi/bacteria get energy and the fungi/bacteria give nitrogen and other nutrients that the plant was lacking. Hope this answered your question.
