Mark the mismatched pair.
(a) Amyloplast—Store protein granule
(b) Elaioplast—Store oils or fats
(c) Chloroplasts—Contain chlorophyll pigments
(d) Chromoplasts—Contain coloured pigments other than chlorophyll
Amyloplasts are non-pigmented organelles found in some plant cells. They are specialized organelles that store starch, through polymerisation of glucose, not protein granules. Hence, the answer is option (a).
