Explanation:

 Learning: 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.
• Single cells, plant cells without cell walls (protoplasts), pieces of leaves, stems or roots can often be used to generate a new plant on culture media given the required nutrients and plant hormones. Different techniques in plant tissue culture may offer certain advantages over traditional methods of propagation, including:
• The production of exact copies of plants that produce particularly good flowers, fruits, or have other desirable traits.
• To quickly produce mature plants.
• The production of multiples of plants in the absence of seeds or necessary pollinators to produce seeds.
• The regeneration of whole plants from plant cells that have been genetically modified etc.
