The three basic tissue systems in the flowering plants from Chapter 6 of NCERT Solutions for Class 11 Biology are
1. Ground tissue system – It is made up of simple tissues such as collenchyma, parenchyma and sclerenchyma.
2. Epidermal tissue system – It includes both epidermal appendages and epidermis. The epidermal appendages include stem hair, root hair, glandular hair and stinging hair, whereas the epidermis consists of guard cells and epidermal cells.
3. Vascular tissue system – It consists of complex tissues such as phloem, xylem and vascular cambium.
