Question

Which one is propagated by cuttings?
(a)Bougainvillea
(b)Tea
(c)Sansevieria
(d)All the above

Answer 1

Examples for a piece of a plant that is used for vegetative propagation in horticulture is a genus of thorny ornamental vines. Some common name of species in a genus is commonly referred to as the mother-in-law tongue, devil's tongue, snake plant, etc and a plant that provides a drink that is aromatic can also be propagated by cuttings.

Complete answer:
Vegetative reproduction is a type of asexual reproduction in which new plants, such as tubers, runners, suckers, rhizomes, etc, are produced from vegetative sections. Any of the plants can be propagated by cutting methods. The section in which the cut is made into a new plant is allowed to expand.
Bougainvillea, Ixora etc. hardwood cuttings can be rooted with a fair amount of success if root-promoting hormones are used. By leaf cutting or planting a leaf section, Sansevieria can be propagated and Tea is propagated by cutting from the end of a branch on the tree below a leaf node that has an axillary bud developing.
A part of the source plant's stem or root is put in an acceptable medium, such as moist soil. The plant piece will begin to grow as a new plant independent of the parent, a process known as striking, if the conditions are suitable. New roots are formed by stem cutting, and new stems are developed by root cutting. Some plants, called leaf cuttings, which produce both stems and roots, can be grown from leaf pieces. Cuttings are also known as the scraps used in grafting.
So, the correct answer is, ‘Bougainvillea’.

Note: It is possible to use several vegetative sections of a plant. Methods that are most common include:
Stem cuts in which a fragment of stem, or at least one leaf node, is partially buried in the soil. The cutting is capable, usually at the node, of generating new roots.
Root cuttings, in which a root section is buried just below the surface of the soil and new shoots are created.
In grafting, scion cuttings are used.
