    Which of the following is maintained for getting good quality meat?
  • Question 4
    1 / -0
    Which of the following species of honey bee is Italian species?
  • Question 5
    1 / -0
    AnimalsUses
    A) Dog1) Agriculture
    B) Llama2) Pet
    C) Bullock3) Food
    D) Fishes4) Fibers
    Solution
    Answer is B.
    A-2, dog is a best pet animal.They are a popular pet because they are usually playful, friendly, loyal and listen to humans.
    B-4,Llamas have a fine undercoat, which can be used for handicrafts and garments. The coarser outer guard hair is used for rugs, wall-hangings and lead ropes.
    C-1,Traditionally farmers used to plough their fields with country plough using bullocks as a source of physical energy.
    D-3,Fish has been an important source of protein and other nutrients for humans. 
  • Question 6
    1 / -0
    The rearing of silkworm for silk is known as
    Solution
    The rearing of silkworm for silk is known as Sericulture.  In sericulture the silkworm are reared at appropriate temperature and humidity to get silk thread from cocoons.
    Hence correct option is A ( Sericluture).
  • Question 7
    1 / -0
    Callus is
    Solution

    Correct Option: D

    Explanation:

    • Callus is a mass of growing, undifferentiated cells that form a plant.
    • Wherever there is presence of abundant cytoplasm, the growth of the callus takes place, since it helps in activating cell division.
    • The growth hormones act so as to help it in differentiation.

    Hence, callus is unorganised actively dividing mass of cells maintained in culture.

  • Question 8
    1 / -0
    Tissue culture is
    Solution
    Tissue culture is a biological technique which involves the development of plant under the controlled condition on a nutrient culture medium of the known composition. The pant developed by the tissue culture are cloned and maintained by the process of micropropagation. Gottlieb Haberlandt was the first to attempt tissue culture. He was first to point out the possibilities of the culture of isolated tissues.
    The cultured cells forms callus. Callus when treated with auxin it promotes rooting and when it is treated with cytokinin it stimulates cell maturation, differentiation and finally, promotes the development of stem.
    So, the correct answer is option D.
  • Question 9
    1 / -0
    Part of plant used for culturing is called:
    Solution
    A piece of young stem or bud which is inserted into a rootstock is called scion.
    Tissue culture is a biological technique which involves the development of the plant by the totipotent cells under the controlled condition on a nutrient culture medium of the known composition. The totipotent cells are taken from the active part of the plant like root, stem leaf, pollen etc. The plant part which is used for the culture is known as explant. 
    A rooted stem into which a scion or a bud is grafted is called a stock.
    Callus is unorganized actively dividing the mass of cells maintained in culture. It has a meristematic cell which has ample amount of cytoplasm to trigger cell division. It is treated with the growth hormones to allow the cell division and differentiation. 
    So, the correct answer is option B.
  • Question 10
    1 / -0
    The structure employed by White for first successful tissue culture was
    Solution
    White was the first one to successfully attempt the technique of tissue culture. He cultured tomato roots in a nutrient media composed of vitamins. He developed the continuously growing callus from the root which had the property of totipotency. The totipotent cells of the roots of tomato undergo cell division and form a mass of active cell known as callus. Callus when treated with auxin it promotes rooting and when it is treated with cytokinin it stimulates cell maturation, differentiation and finally, promotes the development of stem.
    So, the correct answer is option C.
