Question

Which of the following is not a function of epidermis?

• B. Gaseous exchange
• C. Conduction of water
• D. Transpiration

Answer 1

Answer: (C)

Conduction of water

• Epidermis is a single layer of cells found on theouter layers of different parts of a plant -leaves, flowers, roots, stem, etc. Its functions are as follows:
• It forms a barrier between the underlying tissues in a plant and the surrounding environment, thereby, protecting it from adverse environmental conditions.
• The presence of stomata and guard cells in the epidermal tissue helps in the exchange of oxygen, carbon dioxide as well as permit transpiration.

• Conduction of water and minerals in plants takes place in conducting vessels, located in the core, called xylem. Thus conduction of water is not the function of the epidermis.

Hence the correct option is C.
