Question

The symbiotic relationship between algae and fungus is found in
A) Lichen
B) Mycorrhiza
C) Pneumatophore
D) Bacteriophage

Answer 1

Hint: The symbiosis is a close relationship, between two dissimilar organisms. The various kinds of symbiosis that exist between the organism Commensalism, parasitism, mutualism, symbiosis.
- Symbiosis can further be divided into ectosymbiosis and endosymbiosis based on the need and relationship.

Complete Answer:
- The algae and fungus both are found in lichens. A Lichen is not a single organism but it is a symbiotic relationship between fungi and photosynthetic organisms that can be either algae or cyanobacterium.
- A bacteriophage is a virus that can infect bacteria. The bacteriophage attaches to the bacterium and gets incorporated into the bacterium where they can replicate. A virus is a non-living organism, it requires a host to survive or to replicate.
- Mycorrhiza is also an example of a symbiotic relationship, but between a plant and a fungus. The plant in this relationship produces organic molecules such as sugar through the photosynthesis process and supplies them to the fungus. In return, the fungus supplies the minerals, nutrients taken from the soil to the plant.
- The pneumatophores are the specialized aerial roots that aids in breathing. They are generally found in mangrove plants as an adaptive feature for gaseous exchange.

So, lichen is the correct answer.

Note: The algae in the lichen make their food as they are photosynthetic organisms and provide nutrients to the fungus to grow.
