Proteinoplasts
Proteinoplasts originate from plastids. Plastids are specialized double-membrane organelles found in plant cells. Plastids perform a variety of functions such as metabolism of energy, and biological reactions. There are multiple types of plastids recognized including Leucoplasts, Chromoplasts, and Chloroplasts. Plastids are broken up into different categories based on characteristics such as size, function and physical traits. Chromoplasts help to synthesize and store large amounts of carrotenoids. Chloroplasts are photosynthesizing structures that help to make light energy for the plant. Leucoplasts are a colorless type of plastid which means that no photosynthesis occurs here. The colorless pegmentation of the leucopplast is due to not containing the structural components of thylakoids unlike what is found in chloroplasts and chromoplasts that gives them thier pigmentation. From leucoplasts stems the subtype, proteinoplasts, which contain proteins for storage. Other subtypes of Leucoplasts include amyloplast, and elaioplasts. Amyloplasts help to store and synthesize starch molecules found in plants, while elaioplasts synthisize and store lipids in plant cells.
