Micropropagation is a technique
  • For production of somaclonal plants
  • For production of somatic hybrids
  • For production of true to type plants
  • For production of haploid plants
In grafting, the portion to be grafted on the main plant is called
  • Stock
  • Scion
  • Stem
  • Adventitious bud
An edible part of cauliflower is
  • Inflorescence
  • Bract
  • Leaves

There is no natural death in single-celled organisms like Amoeba and bacteria because
  • They are microscopic.
  • They cannot reproduce asexually.
  • They reproduce by binary fission.
  • The parental body is distributed among the offspring.
During favourable conditions, Amoeba reproduces by
  • Binary fission
  • Multiple fission
  • Both of these
  • None of the above
Hydra reproduces asexually through
  • Sporulation
  • Budding
  • Fragmentation
  • Binary fission
Vegetatively propagated plants are
  • Genetically dissimilar
  • Do not bear roots
  • Genetically similar
  • Do not form buds
Why asexual reproduction is sometimes disadvantageous?
  • It produces genetically uniform populations. correct
  • It allows an animal to produce many offspring quickly.
  • It saves the time and energy of gamete production.
  • It allows animals which do not move around to produce offspring without finding mates.
Vegetative propagation in mint occurs by
  • Sucker
  • Rhizome
  • Offset
  • Runner
A scion is grafted to a stock. The quality of fruits produced will be determined by the quality of
  • Stock
  • Scion correct
  • External environmental factors
  • Both stock and scion
