Final answer:
The incorrect statement about transpiration is that it helps in the absorption of minerals from the soil. Transpiration is related to water movement and evaporation, not direct mineral absorption.
Step-by-step explanation:
Among the options provided, the incorrect statement about transpiration is:
(Choice C) Transpiration helps in the absorption of minerals from the soil. While transpiration does create a pull that helps draw water up through the xylem, it is not directly responsible for mineral absorption in the soil. The absorption of minerals is facilitated by other mechanisms in the plant such as active transport and diffusion.
Transpiration is indeed a critical process in plants that involves the evaporation of water from the leaves, mainly through structures called stomata. This process generates a negative pressure that aids in pulling water and dissolved minerals upwards through the xylem from the roots (Choice A). Furthermore, by allowing water to evaporate, transpiration plays a role in cooling the plant and thus is involved in temperature regulation (Choice B). Lastly, stomata, which are found in the epidermis of leaves, are indeed the primary sites of transpiration (Choice D).
