The time duration from the sowing of seeds to the harvest of crops is critical for agricultural purposes. Based on the information above, select a reason why farmers prefer vegetative propagation for growing crops.

A. Seedless crops can also be reproduced.

B. Offspring plants are genetically similar to parent plants.

C. Plants grown by vegetative propagation bear fruits earlier.

D. Vegetative propagation does not depend on external agents of pollination.

 

Answer:

  • Plants grown by vegetative propagation bear fruits earlier. 
  • Vegetative propagation is a type of asexual reproduction
  • This is because plants produced by vegetative propagation are exact copies of their parent
  • They take less time to grow and mature hence, they bear fruits faster than those produced by sexual reproduction.
