Why are fungi so important to plants?

Some fungi help trees and other plants to grow. The roots take up the water and nutrients that the fungi offer and in return the trees and other plants give the fungi sugars that they made during photosynthesis. Photosynthesis is the process where plants can make food using carbon dioxide and energy from sunlight.

What does fungus do for soil?

Along with bacteria, fungi are important as decomposers in the soil food web. They convert hard-to-digest organic material into forms that other organisms can use. Fungal hyphae physically bind soil particles together, creating stable aggregates that help increase water infiltration and soil water holding capacity.

How do fungi negatively affect plants especially agricultural crops?

In addition to destroying plant tissue directly, some plant pathogens spoil crops by producing potent toxins. Fungi are also responsible for food spoilage and the rotting of stored crops. For example, the fungus Claviceps purpurea causes ergot, a disease of cereal crops (especially of rye).

What does baking soda do for plants?
