Meristematic tissue (vascular cambium) produces secondary growth. In plant stems, this serves to increase the diameter, and it forms between the primary xylem and phloem.
secondary xylem
Primary growth is responsible for elongating the plant. In woody plants, primary growth is then followed by secondary growth which allows the plant stem to increase in thickness or girth.
Primary Growth adds height, while secondary growth adds Girth.
one answer: cell growth, which is caused by photosynthesis.
Yes ! They are primary tissues as there is no secondary growth.
Yes ! They are primary tissues as there is no secondary growth.
In a monocot stem, vascular bundles are scattered throughout the stem. However, because the of the lack of vascular cambium, no secondary growth occurs in the monocot stem. As a result of increased cell size, the monocot stem will only increase in height only.

Oppositional growth
during secondary growth the primary epidermis spilt, dries, fall off. to protect the exposed tissues and to increase in diameter cork cambium aries in the cortex.

no there is no cambium present in monocot roots.

Appositional growth occurs on the surface of bones and adds a series of layers to increase the diameter or thickness.
In Japan, the art of growing miniature trees is highly valued. By cutting roots and tips of the branches, gardeners can keep the tree small. The trunk of a tree, however, continues to increase in diameter. How do you explain the ever increasing growth of the diameter of the trunk?Ans:- Secondary growth.Please someone Answer in detail below:-
