When you slice a plant root horizontally and look at its internal tissue arrangement under a microscope, you can instantly identify whether the plant is a Monocot (like grass or wheat) or a Dicot (like a mango tree or sunflower).
In both types of roots, the outermost layer (the Epiblema) produces the tiny, unicellular root hairs that absorb water from the soil.
The Endodermis (inner boundary layer) in dicot roots has distinct waterproof bands called 'Casparian strips'.
Physically, dicots have a primary 'Tap Root' system (one main deep root with smaller side branches, like a carrot). Monocots have a 'Fibrous Root' system (a shallow, bushy network of thin roots, like grass).
