(b) apical meristem
(c) lateral meristem
(d) intercalary meristem.
Answer:
(d) Intercalary meristem is present at the base of internodes or at the base of nodes, and at the base of leaves. This meristem brings about elongation (growth in length) of the part of the plant in which it is present. So even if the tip of the sugarcane plant is removed, i.e. apical meristem is removed. It keeps on growing in length due to the activity of intercalary meristem.
Question 41.
A nail is inserted in the trunk of a tree at a height of 1 metre from the ground level. After 3 years, the nail will
(a) move downwards
(b) move upwards
(c) remain at the same position
(d) move sideways.
Answer:
(c) The nail will remain at the same position after 3 years, but will appear to have sunk into the tree. This is because of the secondary growth of the tree, which increases the girth of a tree. The increase in height of the plant will occur due to primary growth which occurs only in the regions of the apical meristems, i.e. at the tips of the main stem or branches. As increase in height of the tree takes place from top only, therefore the nail will remain at the same position as it is inserted near the ground level.
Question 42.
