Final answer:
True, plants with high levels of xanthophyll are indeed better suited to growth in bright sunlight because these yellow pigments help harvest light energy and protect the plant by dissipating excess energy as heat.
Step-by-step explanation:
Plants that possess high levels of xanthophyll are indeed better suited to growth in bright sunlight. To understand this, let's consider the role of xanthophylls. Xanthophylls are yellow pigments that are part of a group of compounds known as carotenoids. They play an essential role in the photosynthetic apparatus of plants. Xanthophylls act as accessory pigments, helping to harvest light energy by absorbing wavelengths of light that chlorophyll does not absorb as effectively. Additionally, they also protect the plant from the harmful effects of excess light by dissipating excess energy as heat in a process called non-photochemical quenching.
Therefore, the statement that plants with high levels of xanthophyll are better suited to growth in bright sunlight is True.
