Question

How is the mycorrhizal association helpful in absorption of water and minerals in plants?

Answer 1

Mycorrhiza is a symbiotic association of fungi with the root systems of some plants. The fungal hyphae either form a dense network around the young roots or they penetrate the cells of the roots. The large surface area of the fungal hyphae is helpful in increasing the absorption of water and minerals from the soil. In return, they get sugar and nitrogenous compounds from the host plants. The mycorrhizal association is obligate in some plants. For example, Pinus seeds do not germinate and establish in the absence of mycorrhizal.

Answer 2

Mycorrhizal association is useful in absorbing water as well as minerals in the plants by -

In some of the plants, root hairs are not present for absorption. Instead of this, the plants develops a special structure called mycorrhiza which is very useful in absorbing water.

This is an association which is of symbiotic type that is developed between young roots of plants and fungus.

This association helps in absorbing water by providing a large surface area for absorbing purposes.
