Question

Three types of tissue systems have been recognized in plants on the basis of their functions. Select the correct option regarding this.

• A. Epidermal tissue system consists of epidermis and epidermal appendages, which provide protection to the internal tissues.
• B. All tissues except epidermis and vascular bundles constitute the ground tissue, which forms the majority of a plant's body.
• C. Vascular tissue system consists of complex tissues i.e., xylem and phloem.
• D. All of these

Answer 1

The correct option is D All of these

The epidermal tissue system forms the outer covering of a plant, which is in direct contact with the external environment. This tissue system is derived from protoderm and consists of the epidermis and its associated structures, the epidermal outgrowths. The cells perform different functions like protection, absorption, excretion, gaseous exchange, secretion and control of transpiration, etc. The tissue present between epidermis and vascular tissue system constitutes ground tissue system. It forms most of the parts of a plant's body. The vascular tissue system is composed of a number of vascular bundles composed of xylem, phloem and cambium.
