Answer:
Option D. Less; acclimatization. In the summer, leaves of E. farinosa show less pubescence (or hairiness) than in the winter. This change in pubescence is an example of acclimatization.
Step-by-step explanation:
In the case of E. farinosa, the reduction of pubescence during the summer may help to reduce water loss through transpiration, as less surface area is available for water evaporation. This acclimatization helps the plant to conserve water and maintain its hydration in the warmer and drier conditions of the summer. On the other hand, the increased pubescence during the winter may help to protect the plant from the harsh environmental conditions, such as strong winds, frost, and cold temperatures, by providing a physical barrier and insulating the leaves. Overall, the changes in pubescence of E. farinosa are an example of how plants can adapt to their acclimatization and optimize their survival by making adjustments to various physical and physiological traits.
