Which organelles in plants contain pigments that provide color to leaves?

Chloroplasts are the organelles in plants that contain pigments crucial for photosynthesis, which gives color to leaves. These pigments include chlorophyll, which is responsible for the green color of most plant leaves, as it absorbs light in the blue and red wavelengths and reflects green light. In addition to chlorophyll, chloroplasts may also contain other pigments such as carotenoids, which can produce yellow and orange hues, contributing to the overall color of plant leaves, especially during autumn when chlorophyll degrades. This relationship between chloroplasts and leaf color plays a vital role in the process of photosynthesis, enabling plants to convert light energy into chemical energy.

Other organelles listed serve different functions: mitochondria are involved in energy production through cellular respiration, the nucleus houses genetic material and coordinates cell activities, and the Golgi apparatus is responsible for modifying and packaging proteins and lipids. Therefore, chloroplasts are specifically identified as the organelles responsible for the coloration of leaves in plants.
