    Solution

    Nut is a one seeded fruit with a hard pericarp. The cashewnut is true nut as it is enclosed in a hard covering.

  • Question 7
    1 / -0
    Aerial absorptive roots occur in
    Solution
    • The adventitious roots found in the epiphytes are known as the epiphytic root. 
    • These roots hang freely in the air and absorb the moisture from the air by a special type of tissue called velamen. 
    • Epiphytic plants are sometimes called air plants because they do not have roots in the soil. For example, Vanda.
    Hence, the correct option is A.
  • Question 8
    1 / -0
    Velamen is present in
    Solution
    Epiphytic roots are adventitious roots found in the epiphytes. These roots are present in the air and absorb the moisture and nutrients from the air by a special type of tissue called as velamen. Velamen is an outer epidermis layer of epiphytic roots. Since epiphytic plants do not have roots in the soil, they are called as air plants. Epiphytic roots of orchids grow on the surface of other plants for getting shelter.
    Hence, the correct option is B.
  • Question 9
    1 / -0
    Which of the following is not a stem modification?
    Solution

    Solution:
    Correct answer is option B.
    Explanation for correct answer:
    Curcuma amada, or mango ginger is a plant of the ginger family Zingiberaceae.
    It is the modification of root and these adventitious roots become swollen near the apex and form nodule-like structures for storage of food.

  • Question 10
    1 / -0
    Respiratory roots and viviparous reproduction are the characteristic of
    Solution
    Mangrove has aerial roots that are used for respiration or aeration and not for water absorption. Mangrove shows viviparous reproduction because, after pollination, the seeds remain attached to the parent tree. They germinate into propagules before dropping into the waters below. 
    Hence, the correct option is D.
  • Question 11
    1 / -0
    Haustoria or sucking roots occur in
    Solution
    Haustorial roots or sucking roots are found in parasitic plants that fix with the surface of stems and absorb water and nutrients from host plant e.g., Viscum album and Cuscuta.
  • Question 12
    1 / -0
    Pneumatophores or breathing roots occur in
    Solution
    Pneumatophores are specialized aerial roots that enable plants to breathe air in habitats that have waterlogged soil. These roots may grow down from the stem or up from typical roots. For example, Mangrove family of plants (Rhizophoraceae)
    So, the correct answer is 'Mangrove plants'
  • Question 13
    1 / -0
    Potato is multiplied vegetatively with the help of
    Solution
    Tuber is a thickened part of a stem which grows underground. Tubers have bud from which a new plant can arise by vegetative propagation. In vegetative propagation, the top sides of tuber produce shoots and the under sides produce roots. Potato is a modified stem called a tuber.
    Rhizomes are underground stems that grows horizontally below the surface. 
    Corm is an underground swollen stem base covered with scale leaves.
    Phyllode is a petiole which is leaf-like structurally and functionally
    So, the correct answer is 'Tuber'
  • Question 14

  • Question 15
    1 / -0
    In which of the following fleshy tap root hypocotyl does not form root?
    Solution
    Carrot is a modified underground taproot which is conical in shape. The hypocotyl does not form a root in carrot because, during flower initiation, the hypocotyl crown shrinks as carbohydrates and water content is shifted to support flower development and the overall root diameter becomes slender.
    So, the correct answer is option A.
  • Question 16
    1 / -0
    Root pocket occurs in
    Solution
    Root pockets are basically root caps but have lost there utility due to non-use. This is because the roots of the plants that hang freely in water have no friction or resistance from the soil particles to overcome. So, root pockets are vestigial (non-functional) root caps. Once removed, there are not regenerated. Found only in floating aquatic plants like Pistia, water hyacinth and Trapa
    So, the correct answer is 'Water hyacinth'
