What does Phycobiont and mycobiont mean?
Phycobiont refers to the algal component of the lichens and mycobiont refers to the fungal component. Both of these are present in a symbiotic relationship in which algae prepare food for fungi due to the presence of chlorophyll whereas the fungus provides shelter to algae and absorbs water and nutrients from the soil.
What is mycobiont in biology?
Mycobiont is the fungal component of a lichen which provides shelter and absorbs minerals and water for the algae.
What is the Phycobiont organisms in lichens?
Although lichens appear to be single plantlike organisms, under a microscope the associations are seen to consist of millions of cells of algae (called the phycobiont) woven into a matrix formed of the filaments of the fungi (called the mycobiont).

What is mycobiont and photobiont?
Photobiont is the algal component and mycobiont is the fungal component of lichens.
What is the function of mycobiont?
Mycobiont is the fungal partner of lichens. It provides water, nutrients and shelter to the algal partner.
Which among has mycobiont and Phycobiont relations?
In lichens, there is the association of mycobiont and phycobiont called as helotism because in this relationship algae act as a slave, prepare food for fungi and fungi act as master. The reproduction in algae is inhibited by the influence of fungi.

Association between mycobiont and phycobiont are found in (a) mycorrhiza (b) root (c) lichens (d) BGA. Answer: (c) Lichens are dual organisms which has a permanent symbiotic association of fungus and an alga . The fungal partner is called my cobiont an the algal partner is called phycobiont.
Why lichens do not grow in polluted area?
Lichens as Bio-Indicators Lichens are sensitive to atmospheric pollution such as nitrogen (N) because they receive all their nutrients and water from wet and dry atmospheric deposition (fall out). Nitrogen deposition can increase the load of nutrients.
What is the basis of classification of algae?
Algae are classified based on their colour, i.e. presence of certain pigments that impart the specific colour.
What are the two types of organisms that can be the Photobiont in lichen?
Lichens. Lichens are unique, double organisms that consist of two unrelated components, an alga and/or cyanobacterium (photobiont) and a fungus (mycobiont).
Where is Phycobiont found?

Are lichens good or bad?
Are There Any Benefits of Lichen? Surprisingly, lichen can actually be of benefit. It’s a natural air quality indicator, as it absorbs everything in the environment around it, but only thrives when the air quality is clean.
