Name the three basic tissue systems in the flowering plants. Give the tissue names under each system.
The three basic tissue systems in flowering plants are:
-
Epidermal tissue system – This forms the outermost covering of the whole plant body. It comprises epidermal cells, stomata, and epidermal appendages (trichomes and hairs).
-
Ground tissue system – This forms the main bulk of the plant. It consists of simple tissues such as parenchyma, collenchyma, and sclerenchyma. It is divided into three zones: cortex, pericycle, and pith.
-
Vascular tissue system – This is formed by xylem and phloem. It forms the conducting tissue and translocates water, minerals, and food material.
Explanation
According to NCERT Class 11 Biology, Chapter 6 (Anatomy of Flowering Plants), tissues are organized into three systems based on their structure and location. The epidermal tissue system provides protection, the ground tissue system forms the main structural bulk, and the vascular tissue system handles conduction. Students should remember that ground tissue includes parenchyma, collenchyma, and sclerenchyma, while vascular tissue comprises only xylem and phloem.
