Elaioplasts are a type of leucoplast that is specialized for the storage of lipids in plants. Elaioplasts house oil body deposits as rounded plastoglobuli, which are essentially fat droplets.
Being a variety of leucoplast, elaioplasts are non-pigmented and fall into the much broader organelle category of plant plastids. A different example of a storage-specialized leucoplast is the amyloplast, which stores starch.
