Question

Which of the following structure is associated with transpiration?

• A. I, II, III, V and VI
• B. I, V, and VI
• C. VI
• D. II and III
• E. IV and VI

Answer 1

The correct option is E IV and VI

• The upper (I) and lower (V) epidermis together make dermal tissue of the leaf.
• Small pores present in the lower epidermis are called as stomata (VI) and serve in exchange for respiratory gasses.
• Vascular bundles (IV) are involved in the conduction of food and water. Palisade (II) and spongy (III) mesophyll cells have photosynthetic pigments chlorophyll. Mesophyll cells are associated with photosynthesis.
• Loss of water through stomata by the process of evaporation is called transpiration. Transpiration pull drives absorption of water and minerals from root hairs and the ascent of sap in xylem tissues.
  
  Thus, the correct answer is option E.
