Let me share with you a comparison between chloroplast, chromoplast and leucoplast.
| Aspect | Chloroplasts | Chromoplasts | Leucoplasts |
| Pigments | Chlorophyll (chlorophyll a and b) | Carotenoids, xanthophylls and anthocyanins. | Generally lack pigment. |
| Color | Green | Various colors, depending on the type and abundance of pigments | Colorless or pale in appearance |
| Function | Site of photosynthesis, where light energy is converted into chemical energy (glucose) | Responsible for the synthesis and storage of pigments, especially carotenoids | Involved in the storage of starch, lipids and proteins |
| Main Products | Glucose and other organic compounds produced during photosynthesis | Synthesized and stored pigments, which contribute to fruit and flower coloration | Starch, lipids, or proteins, depending on the type of leucoplast |
| Conversion Potential | Can potentially convert into chromoplasts or leucoplasts under certain conditions | Chromoplasts can potentially revert to chloroplasts in certain circumstances | Leucoplasts may differentiate into other plastid types, depending on cellular needs |
| Cellular Location | Distributed throughout the cell, especially in the mesophyll cells of leaves | Can be distributed throughout the cell, often concentrated in the plastid-containing structures | Distributed throughout the cell, with a prevalence in storage tissues |
