Some root structures have the potential to influence mycorrhizal development . Additional information about roots can be found in plant anatomy and plant nutrition texts. The terminology used is explained in the glossary. A sensor network that helps regulate plant growth Absorptive network for limiting soil resources of water and nutrients Mechanical structures that support plants, strengthen soil, construct channels, break rocks, etc. The recognition of different types of roots is important because these can have different functions.
Most plants produce one or more orders of lateral root branches.
Different orders of roots vary in their thickness, branching patterns, growth rates, capacity for secondary growth, lifespans, structural features, etc. These variations will influence their capacities to obtain water and nutrients, support mycorrhizal associations and survive adverse conditions. Higher order lateral roots are generally thinner, shorter and don't live as long as those of lower orders. There are differences between plant species in the proportion of relatively fine or coarse roots they produce. Examples of plants with fine or coarse root systems are shown below.
