Plant Propagation Techniques

591 Questions

Plant propagation techniques cover both natural and artificial methods of cultivating plants, including micropropagation, tissue culture, and layering. These botanical concepts evaluate how desirable characteristics are multiplied and transferred into new plants. Questions on this topic routinely feature in the biology segment of various state and central competitive exams.

A Correct answer
Explanation

Banana plants are typically propagated using rhizomes, which are underground stems that produce new shoots.

Multiple choice
  1. hybridization

  2. genetic recombination

D Correct answer
Explanation

Micropropagation is a technique of plant tissue culture used to produce large numbers of genetically identical plants from small explants under sterile conditions.

Multiple choice
  1. Antigonon

  2. Eichhornia

  3. Ekidea

  4. Amorphophallus

B Correct answer
Explanation

Eichhornia (water hyacinth) is a classic example of a plant that reproduces vegetatively via offsets, which are short, thick runners.

Multiple choice
  1. grafting

  2. paleobotany

  3. embryology

  4. emasculation

A Correct answer
Explanation

In grafting, the scion is the upper part of the plant that is grafted onto the rootstock.

Multiple choice
  1. storage

  2. vegetative reproduction

  3. sexual reproduction

  4. none of these

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The eyes of a potato are axillary buds located on the tuber. These buds can sprout to form new plants, serving as a primary method of vegetative reproduction.

Multiple choice
  1. clonal propagation

  2. induction of somaclonal variations

  3. overcoming hybridization barriers

  4. production of embrayoids

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Embryo culture is often used to rescue embryos that would otherwise abort due to incompatibility between parents, thus overcoming hybridization barriers.
