Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues or organs under sterile conditions on a nutrient culture medium of known composition. Plant tissue culture is widely used to produce clones of a plant in a method known as micropropagation. Agitation during tissue culture serves for:

• Aeration of the culture
• Constant Mixing
• Breakage of cell aggregates in small particles

• Tissue culture, also known as micropropagation, is a propagation method used to produce plants under sterile conditions. 
• This method uses plant explants (plant parts) or seeds that have been sterilized before being placed in containers with a growing medium (usually a gel) that has some nutrients added. 
• Micropropagation is the growing of plants from meristematic tissue or somatic cells of superior plants on nutrient suitable media under controlled aseptic physical conditions.

• Cells derived from a single cell through mitosis constitute a clone and the process of obtaining clones is called cloning (asexual progeny of a single individual make up a clone). 
• Plant tissue culture or micropropagation is the technique of maintaining and growing plant cells, tissues or organs especially on artificial medium in suitable containers under controlled environmental conditions.

• Micropropagation is a more recent practice for growing plants in a culture medium by providing them with all the necessary nutrients and inducing their growth artificially. So, statement A is correct.
• In the case of growth of plants through asexual means using tissue culture, first of all, the mass of cells is formed which is then differentiated into different cells and forms the entire plant body. This cell mass is called callus. So, statement B is also correct.
• Examples of micropropagation growth include orchids, dahlia, etc. So, the statement C is also correct.

Micropropagation is a tissue culture technique for plant propagation in which tissue is taken from a plant and grown in a laboratory to produce plants that are genetically identical to the parent. The small portion of plant tissue, sometimes only a single cell, is placed on a growth medium, typically containing sucrose as an energy source.

Vegetative reproduction is a type of asexual reproduction in which new plants are formed from the vegetative parts like, tubers, runners, suckers, rhizomes etc. Some of the plants can be propagated by the means of cutting. The part which is cut is allowed to grow into a new plant. Stem cutting which can be referred as the cane cuttings are used in the case of sugarcane.
