Read the article When Fungi and Algae Marry by Emily Sohn . What is lichen? What type of relationship do they have? symbiotic, mutualistic, parasitic, etc. Why are lichens so hard to study?

Lichen is a leafy, crusty, growth that is NOT a plant. It's a combination of a fungus and an algae. Lichens are so hard to study because the different varieties of lichen all look very similar. Also, in order to find lichen there has to be specific conditions. The relationship that they have is mutualistic because they monitor air quality.
ReplyDeleteLichen is a symbiotic relationship between fungus and algae. The algae create energy for the fungus using photosynthesis. In exchange for and energy source, the fungus gives the algae a place to live. Though the fungus benefit from this relationship, the algae are do not. Lichens are difficult to study because they are so unique. Lichens have such specific living conditions that it is difficult to study them anywhere except in their natural habitat. Most lichens cannot grow in labs and can grow in very exact locations around the world. Lichens can also be very similar to one another, mistaken easily for each other.
ReplyDeleteLichens grow everywhere, but aren't plants. They are a thriving relationship between alga and fungus. Many scientists feel that the relationship between the alga and fungus is lopsided, because the alga seems to be "caged", or slaving for the fungus to produce the lichen. Lichens are so hard to study because many of the species depend on specific living conditions that are rarely able to achieve in laboratories. However, once they are able to be studied, they can provide alot of information. Scientists are very excited to be able to learn more about lichens. By looking at the lichen's DNA, a family tree can be built, and the evolutionary path can be seen, which can lead to more information about our planet's past.
ReplyDeleteA lichen is an organism that appears as a shrubby, crusty or leafy growth. It is a relationship between two kinds of organisms: an alga and a fungus. The relationship between these two organisms is symbiotic, as each benefits from the partnership- the fungus is given food and the alga is given a place to live. Lichens are very hard to study, however. One reason is because they are very hard to spot. Another reason is because identifying two different kinds can be very difficult, while very closely related species can be found in entirely different environments.
ReplyDeleteLichen is an organism... or actually two organisms. They are actually made up of both algae and fungus. These two organisms have a mutualistic relationship, work together to survive. The algae live on the fungus, but in return they produce energy through photosynthesis. Many scientists are studying Lichens. While there are thousand of Lichens that have been identified, there are still many to go. One reason it is so hard to study them is that they need a very specific environment to grow in and often times scientist cannot grow them in labs. Lichens are now used in the same way as brown pelicans and canary birds are. They are being used as communicators about their environment. Because the lichen’s environment has to be a certain way, the sensitive Lichens will die if the air is polluted. The microscopic organisms are being used to test a places air quality.

ReplyDeleteThey are a symbiotic relationship between algae and fungi. The algae provide energy to the fungus by means of photosynthesis and the fungus provides nutrients and protection from the harsh climate.The two organisms grow together, and their growth rate is extremely slow.Lichens are hard to study because they are hard to identify.Lichens symbiotic relationship is mutualistic.lichens can reproduce sexually, and they are predominantly asexual reproducers
The relationship between algae and fungus is mutual, but not equal. The algae provide food for the fungus, which in turn gives the algae a place to stay. Even though it may sound fair, the algae are trapped, unable to leave even if they wanted to. Lichens appear in almost every environment on Earth, even on a place as harsh as Arctic ice.
ReplyDeleteLichens is a shrubby, crusty, leafy growth of a symbiotic relationship between algae and fungus. The algae gives energy to the fungus through photosynthesis, and the fungus provides shelter to the algae. Lichens are hard to study because scientist have a hard time keeping time alive in laboratories.
ReplyDeleteLichens are microscopic shrubby growths. Lichens are so hard to study because finding them is hard enough already. It is hard for scientists to find different species of lichen because again, they are small and though they look the same, they can be a total different species. Some of the same species of lichen could be as far as the other side of the Earth. They have a mutual relationship between each other because each one is almost the same species.
ReplyDeleteLichen is actually the result of a symbiotic relationship between fungus and algae. A symbiotic relationship is one in which two or more organisms exist in a way that benefits all the organisms in that relationship. Lichens require certain conditions for growth that are unachievable in laboratory settings. This makes them incredibly difficult to study.
ReplyDeleteLichens are shrub like leafy growths. The algae gives food to the fungus, which in turn gives the algae a place to stay. Lichens are everywhere, they live in any environment. Lichens are hard to study because they are so small and it is difficult to tell the lichens apart and they are hard to keep alive in laboratories.
ReplyDeleteA lichen is a symbiotic combination or relation between a fungus and algae. A symbiotic relationship benefits all the life forms that are in the relation. Lichens aren't well adapted so they would die in the process of the experiment. This makes lichen almost impossible to study.

ReplyDeleteA Lichen is a flourishing relationship between a fungus and an alga. They are crispy, shrubby, or leafy growths – although they are not plants. Studying lichens proves to be a challenge. Some can be microscopically small (and therefore hard to spot), identifying them is even harder (since many greatly resemble each other), and most can rarely grow in laboratories. Lichens do have there uses, however. Several different species have been used to make poisons, dyes, a “green” smelling scent for perfume, nests, and even food. But most importantly, the presence of lichens in an ecosystem monitors the air quality, therefore signaling wether the environment is healthy.
lichen is anorgansim that looks scrubby while the algae provide food for the fungus.lichen are found everywhere but very hard to study.including the lab beacuse they are so sensitve of where they grow some labs cant provided them,and so they die.
