Ground tissue in plants (support and storage) includes which tissues?

• A. Cortex, pith, endodermis
• B. Xylem and phloem
• C. Epidermis and stomata
• D. Guard cells and trichomes

Answer: (A)

Ground tissue provides internal support and storage in many plant organs, and its best-known components are cortex and pith. The cortex lies between the epidermis and the vascular bundle and often stores nutrients and helps support the surrounding tissues, while the pith sits at the center and also serves for storage and structural rigidity. The endodermis is a layer derived from ground tissue that surrounds the vascular cylinder and, although its primary role is to regulate water and mineral movement, it is still classified within the ground tissue system due to its origin and relationship to the surrounding tissue. Because of that, cortex, pith, and endodermis together represent the ground-tissue components involved in support and storage. In contrast, xylem and phloem are vascular tissues; epidermis and stomata are dermal tissues; guard cells and trichomes are specialized epidermal cells.
