a) Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem. This can occur through fragmentation and regeneration of specific vegetative parts of plants.

Advantages:

  • Vegetative propagation is a quicker, cheaper and easier method of plant propagation.
  • It makes possible the production of seedless varieties such as banana, orange, jasmine etc.
  • It is more efficient for the plant because no energy is wasted in generating large and showy petals, nectar, fruits, seeds etc.

Two methods employed to grow new plants through vegetative propagation.

  • grafting
  • cutting

b) Complex organisms cannot give rise to new individuals through regeneration because they have organization of their organs system at different levels that's why they can regenerate only few of their lost body parts like skin, blood, muscles, etc. and can't give rise to new individuals.
