Hint:Anomalous secondary growth is a type of secondary growth which deviates from the normal type and is regarded as abnormal or anomalous secondary growth. It results from cell division in cambria or lateral meristems and leads to thickening of the stem root.
Complete answer:
Secondary growth occurs in most seed plants, monocots usually lack secondary growth. If they show secondary growth if it differs from the typical pattern of other seed plants. The formation of secondary vascular tissues from the cambium is a characteristic feature of dicotyledons and gymnosperms. In certain monocots, the vascular tissues are also increased after the primary growth is completed but the cambium of these plants is of a different nature.
The secondary growth is the result of the activity of two lateral meristems, the cork cambium and vascular cambium. Anomalous means abnormal. The anomalous secondary growth occurs in both monocots and dicots. Dracaena is a monocot which shows secondary growth.
Abnormal Secondary growth does not follow the pattern of a single vascular cambium produces xylem to the inside and phloem to the outside.
The correct option is C. Both monocots and Dicots.
Additional information:
Dicots and the group in which all the flowering plants or angiosperms are divided. The seed has two embryonic leaves or cotyledons.
Monocots: These are grass like flowering plants the seeds of which contain only one embryonic leaf.
Note:Some monocot stems increase in diameter due to activity of primary thickening meristem, which is derived from apical meristem. Dicots like Bougainvillea, a series of cambia, arise outside the oldest phloem.
