Detailed explanation-1: -An advantage of tissue culture is that only one plant can be made from a disease free plant. Double eye cuttings are often used when plants have opposite leaves. Herbaceous plants are propagated by cuttings.

Detailed explanation-2: -Following are the various advantages of tissue culture technique: The plantlets are obtained in a very short time with a small amount of plant tissue. The new plants produced are disease-free. The plants can be grown throughout the year, irrespective of the season.

Detailed explanation-3: -Totipotency is the ability of plant cells, where a cell can change to a meristematic state and can be differentiated into a whole plant. This property of plant cells has an advantage over Animal cell tissue culture.

Detailed explanation-4: -They produce exact copies of plants required that have desirable traits. They produce mature plants quickly. Multiple plants are produced in the absence of seeds or necessary pollinators to produce seeds. Whole plants are produced regenerated from plant cells that are genetically modified.

Detailed explanation-5: -Explanation: Plant tissue culture is the technique of in vitro maintain and growing cells, tissues, organs, etc.; and their differentiation on artificial medium under aseptic conditions inside suitable containers.
