Anatomy of Flowering Plants
Name the three basic tissue systems in the flowering plants. Give the tissue names under each system.
The three basic tissue system in plants are:
(i) Epidermal tissue system: It forms the outermost covering of the whole plants body. It comprises of epidermal cells, stomata and the epidermal appendages like trichomes and hairs.
(ii) The vascular tissue system: It consists of the phloem and the xylem
(iii) Ground tissue system: All the tissues except the vascular bundles and the epidermis constitute the ground tissue system. For example parenchyma, collenchyma and sclerenchyma and mesophyll cells.
