  • Question 1
    1 / -0
    Which is the hormone responsible for apical dominant growth?
    Solution
    The apical bud produces an auxin (IAA) that inhibits growth of the lateral buds further down on the stem towards the axillary bud. It was first discovered that the plant hormone auxin likely regulates apical dominance in 1934. Abscisic acid, gibberellins and kinetin does not involves in apical dominance. 
    Therefore, the correct answer is option D.
  • Question 2
    1 / -0
    Which meristem influences the shape of the mature plants? 
    Solution
    Apical meristems are found at the tip of stems and roots. During the cell division, this meristem helps in cellular enlargement and also influences the shapes of the mature plants. Lateral meristems are found along the sides of roots and stems . They play a vital role in increasing the width or diameter of stems and roots. Intercallary meristems are found at the bases of young leaves and internodes. They are mainly responsible for further lengthening of stems and leaves. So, option B is correct.

  • Question 3
    1 / -0
    Pith and cortex belongs to 
    Solution
    In the stem, the pith and the cortex make up the ground tissue. The pith is located within the cylinder of vascular tissue, where it often exhibits a spongy texture because of the presence of large intercellular air spaces. If the growth of the pith fails to keep up with that of the surrounding tissues, the pith may degenerate, producing a hollow stem. In general, roots lack piths, although there are exceptions to this rule. 
    In contrast, the cortex, which is located between the epidermis and the vascular cylinder, is present in both stems and roots. 
  • Question 4
    1 / -0
    The study of tissue is known as:
    Solution
    A tissue is the group of cells with a common origin and performs a specific function and its detailed study is called as histology. 
    Dermatology is the branch of medicine concerned with the diagnosis and treatment of skin disorders. 
    Cardiology is the branch of medicine that deals with diseases and abnormalities of the heart. 
    Cytology is the branches of biology and medicine concerned with the structure and function of plant and animal cells. 
    Thus, the correct answer is option A.

  • Question 5
    1 / -0
    Axillary bud and terminal bud are derived from the activity of
    Solution
    Meristems that occur at the apices of stem, root, and other branches are called apical meristems, which bring about primary growth of the plants, hence also called primary meristems. Hence, the buds (apical and terminal) have meristematic tissues in them.
    Thus, the correct answer is option C.
  • Question 6
    1 / -0
    Pith is a central part of the ground tissue generally made up of
    Solution
    • Pith is a central part of the ground tissue generally made up of parenchyma. It is present in the central portion of the stem. The cells which comprise the pith are rounded in shape. They have large intercellular spaces. 
    • The cells of pith present between the vascular bundles constitute the pith rays, also called medullary rays. These parenchymatous cells are radially arranged in between the bundles and give the appearance of rays. The pith rays help in the radial conduction of food.
    • So, the correct answer is option A.
  • Question 7
    1 / -0
    The vascular cambium in dicots is
    Solution
    Secondary growth in dicot stem occurs by increase in lateral thickening which is also called as secondary thickening or secondary growth. Vascular cambium initiates intrastelar secondary growth. Hence, vascular cambium grows by division of lateral meristem.
    Thus, the correct answer is option A.
  • Question 8
    1 / -0
    Centripetal xylem is the characteristic of
    Solution
    Xylem development in the roots is from the outer regions in the inward direction and so known as centripetal. The growth of xylem in shoots is centrifugal direction which means towards the outside. Phloem development is in the centripetal direction in roots and shoots.
    Thus, the correct answer is option A. 
  • Question 9
    1 / -0
    Increase in circumference of stem is due to the activity of
    Solution
    During secondary growth, when the cells of interfascicular parenchyma and procambium divide and differentiate vascular cambium is produced. When the vascular cambium undergo multiplicative division produces more initial cell and result in the increased circumference of vascular cambium which leads to the increase in circumference of stem.
  • Question 10
    1 / -0
    Tissue means _________________.
    Solution
    Generally, some group of cells have same function and structure and also are derived from same origin. These group of cells are called tissue. 
    So, the correct option is B.
