NEET 2008 Biology question

The length of different internodes in a culm of sugarcane is variable because of

(1)Intercalary meristemCorrect
(2)Shoot apical meristem
(3)Position of axillary buds
(4)Size of leaf lamina at the node below each internode

Answer: (1)

Solution

Intercalary meristems are located at the base of internodes (and leaf bases) in monocots like grasses and sugarcane; their activity lengthens individual internodes, so internode lengths in a culm differ depending on the degree of activity of each intercalary
