it doesn't plant's get thicker with time.
These regions, where cells continuously divide, are where plant growth originates.
To divide by mitosis and produce new cells which will then differentiate into various new specialised tissues.
These regions, where cells continuously divide, are where plant growth originates.
The growth in plants takes place in root and shoot apices. Some intercallary meristem cells also divide and add to growth.
Cells divide very rapidly at root and shoot apices
Because the apical parts in plants have meristematic cells without differentiation into permanent cells. Also apical buds having active cell division have lesser quantity of growth promoting hormones like IAA and cytokinins etc.
It form into two different cells
Apical meristem is found at the tip of the root and shoot and is made of cells that divide at a rapid pace. The apical meristem helps the plant to grow up above the soil and down into the ground. This growth is called primary growth.
meristematic tissue (:
transformed cell lines divide more rapidly and do not require attachment to surface for growth, the loose contact inhibition, when reintroduced to animals may form tumours
