Answer 1

The correct option is D Often show a woolly covering

Mycorrhiza are a symbiotic association between plant roots and fungi. Their major role is to enhance nutrient and water uptake by the host plant by exploiting a larger volume of soil than roots alone can do. The mutually beneficial or symbiotic association of a fungus with the root of a higher plant is known as mycorrhiza.

Mycorrhizal roots often show a woolly covering of fungal hyphae. The shape is different from normal root–tuberous, nodulated, coralloid. Root cap and root hairs are absent.

The correct answer is "option B"
