These are the plants which include crops, ornamentals, fruit trees, etc. These plants require human care and protection because they are cultivated by the breeding techniques and artificial selection method. There are many varieties of cultigens which are produced by genetic modification.

    Thus, the correct answer is option C. 
  • Question 4
    1 / -0
    Vegetative propagation through cell or tissue culture is known as
    Solution
    Micropropagation is culture of apical shoots, axillary buds and meristems on suitable nutrient medium to produce a genetically identical progeny. Macropropagation is production of progeny by means of conventional techniques including cuttings, air-layering and grafting. Production of genetically identical cell lineage or organisms is called as cloning. It includes both conventional and tissues culture techniques. Asexual propagation refers to production of progeny by single parent plant, it can occur through vegetative propagules (rhizome, tubers and bulb) or by artificial methods (cutting, and grafting).
    Hence, the correct option is C.
  • Question 5
    1 / -0
    Cattle husbandry is done for which of the following purposes?

    (i) Milk production
    (ii) Agricultural work
    (iii) Meat production
    (iv) Egg production
    Solution
    • Cattle husbandry is defined as the management of cattle by humans for monetary gains, yielding good quality and quantity milk, help in agriculture and farming and give a huge quantity of meat.
    • The milch animals like buffaloes, cow, she-goat gives milk and the other cattle which do not give milk like bulls are called draught animals as they help in farming like tilling, cart driving and irrigation.

    So, the correct answer is option A.
  • Question 6
    1 / -0
    The commercial rearing of honey bee is known as
    Solution
    Beekeeping or Apiculture is the process or raising and maintaining honeybees to produce honey and market on a large scale. It also deals with the study of honey bee. 
    Therefore, the correct answer is option B.
  • Question 7
    1 / -0
    A particular species of algae is said to have 65-71 % complete protein with all essential amino acids in perfect balance. In comparison, beef has only 22% protein. Which of the following algae is being discussed in the above case?
    Solution
    Spirulina is a cyanobacterium. This is a spiral shaped alga. The algae are considered as a source of many elements like iron, manganese and chromium. There are many essential amino acids which make the algae a rich source of protein. The protein content of this algae is considered more than the beef. The protein tablets or powder is made from this algae which can be used as food supplement.  
    Thus, the correct answer is option B. 
  • Question 8
    1 / -0
    The nectar of plants is sucked by
    Solution
    Bees and hummingbirds, thus play a great role in pollination. Basically, nectar provides an important energy source (carbohydrate) – it supplies a complex range of sugars, whilst pollen gives vital protein and fats.
    Honeybee collects the nectar as a source os nutrients of food material.
    Hummingbirds are very small birds with a high metabolism. A great deal of energy is spent flying, so they must feed almost constantly. Hummingbirds can consume up to twice their body weight in nectar every day. 
  • Question 9
    1 / -0
    Like humans, the hairy skin of the sheep has ........ type of fibers.
    Solution
