  • Question 1
    1 / -0
    Who is known as father of plant tissue culture?
    Solution
    • In 1902, a German Botanist, Professor Gottlieb Haberlandt, first pointed out the possibilities of the culture of isolated tissues, plant tissue culture.
    • He is known as the father of plant tissue culture.


    So, option A is the correct option.
  • Question 2
    1 / -0
    Which poultry breed is not an English breed?
  • Question 3
    1 / -0
    Apiculture is associated with groups of plants ______________.
    Solution
    Apiculture is basically associated with the flowering plants. It refers to the scientific way of beekeeping. It helps in the growth of Guava, sunflower, strawberry, pineapple, etc.

  • Question 5
    1 / -0
    Which of the following is the most recent domestication?
    Solution
    So the correct option is C.

  • Question 6
    1 / -0
    With reference to mass selection of crop plants, consider the following statements.

    a. Mass selection has been more commonly used for the improvement of cross-pollinated crops than the single plant selection.
    b. The purpose of mass selection is to increase the frequency of superior genotypes in the population.
    c. This method of breeding has been very effective in improving characters governed by many genes.

    Which of the statements given are correct?
    Solution
    The correct answer is A.
    The advantage of mass selection of crop plants are
    1) Varieties developed by mass selection have wide adaptability, wide genetic base and stability.
    2) Rapid, simple and least expensive of plant-breeding procedures. Retains considerable genetic variability
    3) Of use for the improvement of land races.
  • Question 7
    1 / -0
    Haploids are useful for ________________.
    Solution
    Chromosome counts showed that the callus produced was haploid when the anthers 1) were of a dark-brown to black color, and 2) were cultured in the late tetrad stage of microspore development.. Diploid plants were obtained when the anthers had been cultured in the dark.
    So, the correct option is 'A'.
  • Question 8
    1 / -0
    Electroporation is a technique commonly used in ________________.
    Solution
    B. Somatic Hybridization
    Solution : Electroporation is commonly used in the fusion of two protoplasts also called somatic hybridization to create a somatic hybrid. An electric pulse is used to fuse two cells into a hybrid.
    So the correct answer is " Somatic Hybridization"
  • Question 9
    1 / -0
    The callus is defined as ________________.
    Solution
    D. Undifferentiated mass of cells
    Solution : Callus is and undifferentiated mass of cells produced generally in tissue culture.It is derived from a source tissue in in vitro conditions ready for tissue culture.
    So the correct answer is " Undifferentiated mass of cells"
  • Question 10
    1 / -0
    Which is the best method of germplasm conservation?
    Solution
    Seed banks are the best method of germplasm conservation. It stores seeds to preserve the genetic diversity. Seeds remain viable for hundreds and even thousands of years. Thus it is the best method to combat the loss of genetic diversity in rare or imperiled plant species in an effort to conserve biodiversity ex-situ. 
    So, the correct answer is 'Seed bank'.
