In plants, growth is restricted to specific regions because of the presence of dividing tissues, which are also known as __________.
Meristematic tissues
Plant growth does not occur uniformly throughout the plant body but is confined to certain active regions such as root tips, shoot tips and the cambium.
These specific regions contain cells that continuously and actively divide, allowing the plant to increase in length or girth at those locations.
Such actively dividing tissue is called meristematic tissue, as opposed to permanent tissue, which consists of cells that have stopped dividing and taken up a specific function.
Hence, growth in plants is restricted to regions containing meristematic tissue.
