Advantages of Vegetative Propagation

The advantages of vegetative propagation are as follows:

 Plants that do not produce seeds can be grown by this method.
 Vegetative plants grow faster than the ones produced by seeds.
 The plants reproduced by this method are exactly the same as the original
plant.
 These plants need less attention as compared to the plants grown by other
types of reproduction.

Tissue Culture

 Many plant cells have the ability to divide and differentiate into an entirely new
plant. This property of plant cells is used in growing new plants under sterile
or germs–free condition and is known as the tissue culture technique.

 In this technique, the plant cells from different parts of a plant are cultured in
the laboratory to develop a new plant. This technique is helpful in increasing
the number of rare and endangered plant species that are unable to grow
under natural conditions.

 In this method, some tissue is cut off from the growing tip of the plant. This
tissue is then separated into cells. These cells are put in a nutrient medium
containing inorganic salts, sugar, vitamins, and hormones which are required
for growth and differentiation of cells. Cells are allowed to grow into small
