Here's why:
* Chloroplasts: These are the plastids responsible for photosynthesis and contain chlorophyll, giving plants their green color.
* Chromoplasts: These plastids are responsible for storing pigments other than chlorophyll, such as carotenoids. Carotenoids give fruits and vegetables their yellow, orange, red, and purple colors.
In the case of brinjal (eggplant), the green color is due to chlorophyll present in the chloroplasts. As the brinjal matures, chlorophyll breaks down, and the chromoplasts start accumulating anthocyanins, which are pigments that give the brinjal its purple color.
Therefore, the chromoplasts are directly involved in the color change from green to purple in brinjal.
