BOTANY

Detailed explanation-1: -In sugarcane the roots that arise from the lower nodes of the stem are called stilt roots for the support of plant.

Detailed explanation-2: -Maize and sugarcane show the presence of stilt roots. The lower nodes of maize and sugarcane stem elongate to form adventitious root fibers that are called stilt roots. These roots provide extra support to the plants that are weak in nature.

Detailed explanation-3: -So, the correct option is ‘Stilt roots’.

Detailed explanation-4: -Hence, they are termed as adventitious roots. In sugarcane, adventitious roots are stilt roots or brace roots. Prop roots are aerial roots that are developed from the horizontal branches of the stem that hang vertically downwards. They provide mechanical support to the plant.

Detailed explanation-5: -A sugarcane plant is a tuft of between 5 and 20 upright stems, or “tillers", 2 to 5 metres tall and 2 to 4 centimetres in diameter. Each stem is a succession of nodes and internodes; each node bears a bud and a band of root primordia. The sugar is stored in the pith, under the hard, waxy bark.
