Symbiosis (from Greek σύν "together" and βίωσις "living") is close and often long-term interaction between two different biological species. In 1877 Albert Bernhard Frank used the word symbiosis (which previously had been used to depict people living together in community) to describe the mutualistic relationship in lichens. In 1879, the GermanmycologistHeinrich Anton de Bary defined it as "the living together of unlike organisms."
The definition of symbiosis has varied among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to any type of persistent biological interaction (in other words mutualistic, commensalistic, or parasitic). After 130 years of debate, current biology and ecology textbooks now use the latter "de Bary" definition or an even broader definition (where symbiosis means all species interactions), with the restrictive definition no longer used (in other words, symbiosis means mutualism).
Some symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival. For example, many lichens consist of fungal and photosynthetic symbionts that cannot live on their own. Others are facultative (optional): they can, but do not have to live with the other organism.

Normally when people talk about "symbiosis", they're talking about two or more different organisms cooperating to better survive and reproduce. The classical definition of symbiosis is actually much broader than this, and for good reason. Here we will look how evolutionary biologists understand symbiosis, all its different forms, and why it matters!

Symbiosis
With so many organisms on Earth, living things are bound to interact with one another. Symbiosis is a close relationship between two species.
One type of interaction between two species is called mutualism. An example of mutualism exists between honey bees and flowers. Flowers provide nectar to the bees. The bees use the sugar rich liquid to make honey. As the bees fly from flower to flower tiny grains of pollen get stuck to the bee. The bee moves the pollen without even knowing it. The pollination is necessary for flowers to reproduce. In this relationship both species benefit. The bee gets nectar and the flower gets pollinated.
Another relationship is called commensalism. This interaction takes place when sharks and remora live together. The remora use sucking disks on the...

With so many organisms on Earth, living things are bound to interact with one another. Symbiosis is a close relationship between two species.
One type of interaction between two species is called mutualism. An example of mutualism exists between honey bees and flowers. Flowers provide nectar to the bees. The bees use the sugar rich liquid to make honey. As the bees fly from flower to flower tiny grains of pollen get stuck to the bee. The bee moves the pollen without even knowing it. The pollination is necessary for flowers to reproduce. In this relationship both species benefit. The bee gets nectar and the flower gets pollinated.
Another relationship is called commensalism. This interaction takes place when sharks and remora live together. The remora use sucking disks on their heads to attach themselves to sharks. The sharks are powerful swimmers and do not even notice the remora and are neither helped nor harmed. However the remora benefit from this relationship. The fish get a free ride and protection. They also feed on scraps left over by the shark. In commensalism one species benefits and the other is neither helped nor harmed.
The last type of symbiotic relationship is called parasitism. An example of this relationship exists between humans and mosquitoes. The insects land on and take the blood from humans. The mosquito benefits as it uses the blood for energy. The human or host is harmed in this relationship as blood is needed and the human could become infected with disease. In parasitism one species benefits and the other is harmed.

Normally when people talk about "symbiosis", they're talking about two or more different organisms cooperating to better survive and reproduce. The classical definition of symbiosis is actually much broader than this, and for good reason.

With so many organisms on Earth, living things are bound to interact with one another. Symbiosis is a close relationship between two species.
One type of interaction between two species is called mutualism. An example of mutualism exists between honey bees and flowers. Flowers provide nectar to the bees. The bees use the sugar rich liquid to make honey. As the bees fly from flower to flower tiny grains of pollen get stuck to the bee. The bee moves the pollen without even knowing it. The pollination is necessary for flowers to reproduce. In this relationship both species benefit. The bee gets nectar and the flower gets pollinated.
Another relationship is called commensalism. This interaction takes place when sharks and remora live together. The remora use sucking disks on their heads to attach themselves to sharks. The sharks are powerful swimmers and do not even notice the remora and are neither helped nor harmed. However the remora benefit from this relationship. The fish get a free ride and protection. They also feed on scraps left over by the shark. In commensalism one species benefits and the other is neither helped nor harmed.
The last type of symbiotic relationship is called parasitism. An example of this relationship exists between humans and mosquitoes. The insects land on and take the blood from humans. The mosquito benefits as it uses the blood for energy. The human or host is harmed in this relationship as blood is needed and the human could become infected with disease. In parasitism one species benefits and the other is harmed.

Symbiosis is close and often long-term interaction between different biological species.
The definition of symbiosis is controversial among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to all types of persistent biological interactions (i.e. mutualistic, commensalistic, or parasitic).
In this video we show how you can simply visualize all three.

Symbiotic relationships are often encountered in nature. Sometimes we can observe them with a naked eye, for instance the absolute interdependence between bees and flowering plants. However, sometimes we need special equipment, such as a microscope to observe a symbiosis.

Symbiosis (from Greek σύν "together" and βίωσις "living") is close and often long-term interaction between two different biological species. In 1877 Albert Bernhard Frank used the word symbiosis (which previously had been used to depict people living together in community) to describe the mutualistic relationship in lichens. In 1879, the GermanmycologistHeinrich Anton de Bary defined it as "the living together of unlike organisms."
The definition of symbiosis has varied among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to any type of persistent biological interaction (in other words mutualistic, commensalistic, or parasitic). After 130 years of debate, current biology and ecology textbooks now use the latter "de Bary" definition or an even broader definition (where symbiosis means all species interactions), with the restrictive definition no longer used (in other words, symbiosis means mutualism).
Some symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival. For example, many lichens consist of fungal and photosynthetic symbionts that cannot live on their own. Others are facultative (optional): they can, but do not have to live with the other organism.
The exhibition hall integrates science education, exhibitions, experiences, and interactions, leading the public to focus on the most positive symbiotic relationships between fungi and plants, fungi and humans, from a museum perspective.
