Answer 2

Let me introduce you to the role and world of Mycorrhiza. Mycorrhiza are of two types and they are discussed below :

(1) Ectomycorrhiza : In this case the fungus lives outside the tissues of root of Pine, Oak, Eucalyptus, Alnus, Betula, etc. The fungus replacing the normal root hairs of the plants forms a covering or mantle outside the roots of the trees. This mantle serves as root hair and increases surface area of absorption, thereby increasing uptake of water and mineral nutrients.Ectomycorrhizal fungi form mainly with Conifers and Hardwoods, and are required mostly for woody plants/trees and forest trees. Approximately 10% of terrestrial plant species on Earth are ectomycorrhizal.

(2) Endomycorrhiza : On the other hand, endomycorrhizae are found in over 80% of extant plant species -including crops and greenhouse plants such as most vegetables, grasses, flowers, and fruit trees. Endomycorrhizal relationships are characterized by a penetration of the cortical cells by the fungi and the formation of arbuscules and vesicles by the fungi. In other words, endomycorrhiza have an exchange mechanism on the inside of the root, with the fungi’s hyphae extending outside of the root. It is a more invasive relationship compared to that of the ectomycorrhiza.Examples: Most Vegetables, Grasses, Flowers, Shrubs, Fruit Trees, and Ornamentals. Approximately 85% of terrestrial plant species on Earth are endomycorrhizal.
