Final answer:
November leaves are less important for photosynthesis but are part of the plant's adaptation to seasonal changes. Their color change is due to less chlorophyll, which allows other pigments to show.
Step-by-step explanation:
Regarding the question about what can be inferred about November leaves, option A suggests they are no longer as important as in earlier months. In autumn, leaves undergo a change in color, brought about by environmental changes such as shorter days and cooler temperatures, meaning less chlorophyll is produced. As chlorophyll production lessens, the other pigments in leaves become visible, leading to the vibrant color changes that characterize fall foliage.
So, based on the information provided, we can infer that November leaves exhibit their color due to changed environmental conditions, not because they are less important. While they do not contribute directly to the growth of new leaves, their shedding in the fall is integral to the cycle of a deciduous plant’s life, as it allows the plant to conserve resources such as water during the winter and prepares the plant for new growth in the spring.
