The length of different internodes in a culm of sugarcane is variable because of:
Correct answer: B. Intercalary meristem
- A. Size of leaf lamina at the node below each internode
- B. Intercalary meristem
- C. Shoot apical meristem
- D. Position of axillary buds
Explanation
Internode is the part of a plant stem, that occurs between two adjacent nodes. Interca lary meristem are internodal in position and is found in the stem of grasses and other monocotyledonous plants. In early stages the internode is wholly or partially meristematic but later on some of itsparts become matured more rapidly than the rest so a definite continuous sequence of development is maintained i.e., mature tissue left behind whereas new ones grow which later shows variable length.
