How do plants respond to light and what mechanisms do they use to adapt to different light conditions?

Plants respond to light through a process called photomorphogenesis, where they adjust their growth and development based on the quality, intensity, and duration of light. They use photoreceptors, such as phytochromes and cryptochromes, to sense light and regulate gene expression. Plants can adapt to different light conditions by changing their leaf orientation, adjusting chlorophyll levels, and altering their growth patterns to optimize photosynthesis.
