Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What method involves taking segments of leaves, stems, or roots and placing them in growing media to develop into new plants?
A
Cuttings
B
Division
C
Grafting
D
Layering
Explanation: 

Detailed explanation-1: -Asexual propagation, sometimes referred to as vegetative propagation, involves taking vegetative parts of a plant (stems, roots, and/or leaves) and causing them to regenerate into a new plant or, in some cases, several plants.

Detailed explanation-2: -Asexual propagation involves taking a part of one parent plant and causing it to regenerate itself into a new plant. The resulting new plant is genetically identical its parent. Asexual propagation involves the vegetative parts of a plant: stems, roots, or leaves.

Detailed explanation-3: -Asexual propagation It is also called ‘vegetative propagation’. The vegetative parts of a plant like leaf, stem, root or their modified forms are used for propagation. Most of the horticultural crops are commercially propagated by vegetative or asexual method of propagation.

Detailed explanation-4: -Plants propagated using these methods have the same characteristics as the parent or source plant since vegetative material is used and no genetic recombination is involved. The key techniques for propagation that will be highlighted are: leaf cuttings, stem cuttings, simple layering, and air layering.

Detailed explanation-5: -The development of roots on a stem while the stem is still attached to the parent plant is called layering. A layer is the rooted stem following detachment (removal) from the parent plant. Some plants propagate naturally by layering, but sometimes plant propagators assist the process.
