  • Question 10
    1 / -0
    Regions of root from base to root tip are:
    Solution
    Regions of root from base to root tip are as follows :
    Zone of maturation - The elongating cells complete their differentiation into the tissues of the primary body in this zone. It is easily recognized because of the numerous root hairs. 
    Zone of cell elongation - Cellular expansion in this zone is responsible for pushing the root cap and apical tip forward through the soil.
    Zone of cell division - This zone has apical meristem cells which give rise to the primary body of the plant. It is the area under and behind the root cap. 
    So, the correct answer is 'Maturation zone - Elongation zone - Cell division zone'

  • Question 11
    1 / -0
    In Ipomoea batatas (Sweet potato), the food is stored in
    Solution
    The sweet potato (Ipomoea batatas) is a dicotyledonous plant that possesses tuberous root and modified to store food materials and become swollen. It is rich in simple starches, complex carbohydrates, dietary fibre and beta-carotene. Thus, the correct answer is option A.

  • Question 12
    1 / -0
    Clinging and epiphytic roots are found in ?
    Solution
    Clinging root and epiphytic roots are found in epiphytic plants. This is a type of root in which the plant fixes itself to the bark of the tree and develops clinging or aerial roots. These type of roots are useful for absorption of water from the atmosphere and little nutrients found in the tree bark. The common example is orchids.
    Thus, the correct answer is option A. 
  • Question 13
    1 / -0
    Nodulated roots bearing family is
    Solution
    Root nodules or swellings are found on the roots of plants in subfamily Papiliodnideae of family Fabaceae or Leguminosae (e.g., pea, gram). These nodules contain symbiotic nitrogen-fixing bacteria which convert nitrogen gas from the atmosphere into ammonia. This process is called nitrogen fixation. 

    Thus, the correct answer is option C.
  • Question 14
    1 / -0
    Sweet potato is modification of
    Solution
    Sweet potato is an example of tuberous roots where a portion of the root swells for food or water storage. It stores simple starch, fibres, complex carbohydrates etc.
    Hence, the correct option is B.
  • Question 15
    1 / -0
    Which modification of root does not store food?
    Solution
    Stilt roots arise from the first few nodes of the stem. These penetrate down into the soil and give support to the plant e.g., maize and sugarcane. Whereas tuberous, napiform and conical roots are the types of tap root and modified for food storage.
    Hence, the correct option is D.
  • Question 16
    1 / -0
    White spongy floating roots occur in
    Solution
    Modified roots which are white, spongy and filled with air are called as floating roots. An air helps the plants to float on water as well as in breathing e.g., aquatic plants like Jussiaea. 
    Therefore, the correct option is D.
  • Question 17
    1 / -0
    Epiphytes like Vanda, develop special layer of absorptive tissue velamen consisting of 4 or 5 layers of long polygonal cells. Velamen is formed by
    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 as velamen. Epiphytic plants are sometimes called as air plants because they do not have roots in the soil e.g., Vanda. Hence, the correct option is D.
  • Question 18
    1 / -0
    Buttress roots are
    Solution
    Buttress root extends above ground as a plate-like an outgrowth of the trunk supporting the tree. Buttress roots are mainly found in trees of tropical rainforests.

    Hence, the correct option is D.
  • Question 19
    1 / -0
    Climbing roots occur in
