प्रश्न
Give two examples for mycorrhizae forming fungi.

उत्तर
The symbiotic association between fungal mycelium and the roots of plants is called mycorrhizae. In this relationship, fungi absorb nutrition from the root, and in turn, the hyphal network of mycorrhizae forming fungi helps the plant to absorb water and mineral nutrients from the soil.
Examples
- Orchid mycorrhiza
As mentioned above, some orchids cannot photosynthesize prior to the seedling stage. Other orchids are entirely non-photosynthetic. All orchids, however, depend on the sugars provided by their fungal partner for at least some part of their lives. Orchid seeds require fungal invasion in order to germinate because, independently, the seedlings cannot acquire enough nutrients to grow - Arbuscular Mycorrhiza
Arbuscular mycorrhizae are the most widespread of the mycorrhizae species and are well known for their notably high affinity for phosphorus and ability for nutrient uptake.
