Worked practice questions

The science of changing the traits of plants to get desired characteristics is called

  1. Plant breeding
  2. Biofortification
  3. Tissue culture
  4. Sericulture
Show answer and solution

Correct answer: A. Plant breeding

Plant breeding deliberately alters plant traits to improve yield, quality and tolerance.

Selectively propagating plants with desirable traits and culling the poor ones is called

  1. Protoplast fusion
  2. Selective propagation
  3. Cross hybridisation
  4. Induced mutagenesis
Show answer and solution

Correct answer: B. Selective propagation

Selection keeps the best plants for propagation and eliminates the less desirable ones.

Plant breeding began with the domestication of crops about how many years ago?

  1. 1,000 to 2,000 years
  2. 9,000 to 11,000 years
  3. 200 to 300 years
  4. 90,000 to 110,000 years
Show answer and solution

Correct answer: B. 9,000 to 11,000 years

Early farmers began choosing plants with useful traits with the start of settled farming roughly 9,000 to 11,000 years ago.
