The ground tissue system
- All tissues except epidermis and vascular bundles constitute the ground tissue.
- In leaves, the ground tissue consists of thin-walled chloroplast containing cells called mesophyll.
- It consists of simple tissues such as parenchyma, collenchyma and sclerenchyma.
- Parenchymatous cells are usually present in cortex, pericycle, pith and medullary rays, in the primary stems and roots.
