Examine the three main plant tissue systems. Discover how epidermal tissues protect plants, ground tissues provide structure, and vascular tissues transport water and nutrients.
In radial vascular bundles, xylem and phloem are arranged alternately, as seen in roots.

Xylem is a part of the vascular tissue system, whereas stomata, trichomes, and epidermal cells belong to the epidermal tissue system.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
The vascular tissue system, consisting of xylem and phloem, is responsible for the conduction of water, nutrients, and food in plants.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
The epidermis is usually covered by a waxy cuticle to prevent excessive water loss.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
Radial vascular bundles are found in roots, where xylem and phloem are arranged separately along different radii.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
Ground tissue plays a major role in storage, support, and photosynthesis.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
Guard cells regulate the opening and closing of stomatal pores to control transpiration and gas exchange.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
The ground tissue consists mostly of simple tissues like parenchyma, collenchyma, and sclerenchyma.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
The ground tissue system includes mesophyll, which contains chloroplasts and plays an essential role in photosynthesis.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
The epidermis is a single-layered protective layer in plants. It is made up of living cells, and the cuticle is absent in roots.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
Leaves have conjoint vascular bundles where xylem and phloem are together on the same radius.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Tissue System - Epidermal Ground and Vascular
Dicot leaves have stomata, primarily on the lower epidermis, for gas exchange and transpiration.
