Question

Define anamolous secondary growth in thickness with suitable sketches?​

Answer 1

Explanation:

Secondary Growth  An increase in plant girth due to vascular cambium or cork cambium is called secondary growth. ... As a result, the secondary plant structures that are formed are termed anomalus. Most anomalous growth is associated with the formation of multiple cambia.

Answer 2

Answer:

secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue. Secondary growth occurs in most seed plants, but monocots usually lack secondary growth. If they do have secondary growth, 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. In the living Pteridophytes this feature is rare but occurs in plants like Isoetes and Botrychium.
