      • these all processes include both growth and development
  5. Cellular differentiation of structure and function takes place during
    1. growth
    2. development
    3. gastrulation
    4. induction
    5. Show Answer
      Answer: B
      Explanation:
      • Growth is increase in size so answer is Development
  6. Addition of new branches,roots,leaves and elongation of roots and shoots in plants is a type of growth pattery known as
    1. growth
    2. open growth
    3. growing points
    4. development
    5. Show Answer
      Answer: B
      Explanation:
      • its open growth because rate of growth is not uniform through out life
  7. In plants cells which have potential to divide and give rise to new cells are known as
    1. meristems
    2. parenchyma
    3. tracheids
    4. complex tissue
    5. Show Answer
      Answer: A
      Explanation:
      • meristems are the types of simple tissues in plants which are responsible for primary and seconday growth
  8. In higher plants growth is limited to certain regions as entire plant is unable to grow so these regions are named as
    1. meristems
    2. intercalary meristems
    3. growing points
    4. nodes

      Answer: D
      Explanation:
      • these all are the types of simple tissues in plants
  10. which of the following is responsible for primary growth
    1. apical meristems
