hello baccho 

In this video you will get some information about plant growth and development.

A group of dividing cell ( meristem ) are found from starting (in seed embryo) which form a baby plant and in a plant it was found at the tip of shoot & root as Root apical meristem and shoot apical meristem.it increase length or height of plant.
Apical meristem differentiates into primary permanent  tissues like parenchyma, sclerenchyma,  primary phloem, primary xylem, medullary Ray. These are primary growth.

primary permanent tissues dedifferentiate into secondary meristmatic tissue like cork cambium, vascular cambium.

secondary meristmatic tissue redifferentiate into secondary permanent tissues like secondary phloem, secondary xylem, cork and secondary cortex. These are secondary growth.It causes inciin girth.
