Question

Callus is the mass of cells that is formed due to:
A. Micropropagation
B. Grafting
C. Budding
D. Layering

Answer 1

Answer:

During the formation of callus tissue, the explants lose its original characteristic. So, under the influence of exogenously supplied hormone, the explants are triggered off a growth sequence in which cell enlargement and cell division predominate to form an unorganised mass of cells.

Answer 2

Callus is the mass of cells that is formed due to Micro propagation.

Option: A

Explanation:  

• Callus is a mass of cell which is unorganised. Micro propagation is a type of tissue culture.  

• In this process the seeds are kept in suitable condition. As a result the proper metabolism takes place inside the seed. When the seed grows into a small plant, the plant is then planted.  

• Since the conditions are kept optimal for the germination of the seed the dormancy of the seed is highly increased in this process.
