Which plastids contain pigments that are used in photosynthesis?

Chromoplasts are the plastids that contain pigments utilized in photosynthesis. These plastids are responsible for the vibrant colors found in many fruits and flowers, and they contain pigments such as carotenoids, which play a crucial role in capturing light energy. This light energy is then converted into chemical energy during the photosynthetic process.

In contrast, amyloplasts are primarily involved in the storage of starch and do not contain pigments associated with photosynthesis. Leucoplasts are also non-pigmented and serve roles in storage, particularly of starches and oils, rather than participating directly in the light capturing process. Peroxisomes, while involved in metabolic reactions that can include some processing of products from photosynthesis, are not plastids and do not contain pigments for photosynthesis. Therefore, the role of chromoplasts in photosynthesis, through their pigment content, clearly identifies them as the correct answer.
