Mention five types of endomycorrhizas and differentiate between endomycorrhizal and ectomycorrhizal association, giving the advantages of each.

As the name suggests (endomycorrhizas), endo means inside. Therefore, the location of the fungal hyphae which can relate to the root tissues of the plant is inside it. Endomycorrhizas can be classified into two major and two minor groups. Examples of endomycorrhizas emcompasing a larger group are:

Both groups specialize in metabolising polysaccharides and proteins for their carbon content.

The advantages of this association is that AM can improve the plant performance even when there is a shortage of water.

Ectomycorrhizal associations, differs from endomycorrhizal ones in the sense that Ectomycorrhizal associations are an advanced symbiotic association between higher plants and fungi. What happens in this association is that the plant root system is absolutely surrounded by a sheath of fungal tissue.

The advantages of this association is that it can establish vegetation and restore habitats.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
