MaximumYield explains Feeder roots
Feeder roots are small, thin, white roots that are difficult to see and barely visible. Their primary function is to absorb water and nutrients from the upper layers of soil. Along with absorbing water and nutrients, these roots also absorb oxygen, which is why these roots spread across the upper layers of the soil. Species of fungi like Mycorrhizae live on the feeder roots, but these fungi don't cause any harm to the plant. Instead, some species of fungi have a very beneficial relationship with the plant.
