Which of the following statements is/are false? A. The waxy substance associated with the wall of cork cells is suberin. B. Abnormal secondary growth observed in Withania. C. Intercalary meristem results in secondary growth.

A. Suberin is a waxy substance found in higher plants. Suberin is the main constituent of cork, and is named after the Cork Oak, Quercus suber. B. Abnormal secondary growth does not follow the pattern of a single vascular cambium, a thick hair clit producing xylem to the inside and phloem to the outside. Some dicots have anomalous secondary growth, e.g. in Bougainvillea, Dracaena. Withania shows normal secondary growth. C. In angiosperms, intercalary meristems occur only in monocots (in particular, grass) stems at the base of nodes and leaf blades and respond to primary growth of stem and root. Hence, B and C are false.
