thickening in plants

Secondary growth - Wikipedia

Secondary growth also occurs in many nonwoody plants, e.g. tomato, potato tuber, carrot taproot and sweet potato tuberous root. A few long-lived leaves also have secondary growth.

secondary thickening facts, information, pictures | Encyclopedia.com ...

secondary thickening (secondary growth) The formation of new tissue by the repeated lateral division of cells in the cambium of a woody plant, adding successive layers of new growth. This increases the girth of the stem or root, and the growth can be seen as annual rings (tree-rings). Much of the woody part of a woody...

Stems | Boundless Biology - Lumen Learning

When the stem is viewed in cross section, the vascular bundles of dicot stems are arranged in a ring. In plants with stems that live for more than one year, the individual bundles grow together and produce the characteristic growth rings. In monocot stems, the vascular bundles are randomly scattered throughout the ground...
