Detailed explanation-1: -Such type of reproduction is known as vegetative propagation. A sweet potato is a swollen root of the plant. The new plant of sweet potato can be grown from the roots of the original plant. Underground stems like potato and ginger have buds on them from where new shoots will grow on planting them in the soil.

Detailed explanation-2: -Sweet potato is a modification of adventitious roots which grow from the nodes of a running stem and they are irregularly swollen due to storage of food. They can give rise to adventitious buds which when detached can give rise to new plants thus performing the function of vegetative propagation.

Detailed explanation-3: -The plant reproduces in three ways: from seed, from the actual storage roots, or from the plant vines. Sweetpotato is cultivated by vegetative propagation. Growers take stem cuttings from the vines, which then root and form new storage roots.

Detailed explanation-4: -(i) Roots of potato cannot give rise to new plants. (ii) Plants produced by vegetative propagation take longer time to grow and bear flowers.

Detailed explanation-5: -They are also called root tubers. Sweet potato is a dicot plant from the family Convolvulaceae. It is an example of an adventitious root and is a modified form of tuberous roots. The food is stored in the form of starch in sweet potatoes.
