Lacking photosynthetic pigments, leucoplasts are located in non-photosynthetic tissues of plants, such as roots, bulbs and seeds.They may be specialized for bulk storage of starch, lipid or protein and are then known as amyloplasts, elaioplasts, or proteinoplasts (also called aleuroplasts) respectively.
Leucoplasts: colourless plastids that synthesize monoterpenes. Leucoplasts differentiate into even more specialized plastids, such as: the aleuroplasts; Amyloplasts: storing starch and detecting gravity—for maintaining geotropism. Elaioplasts: storing fats. Proteinoplasts: storing and modifying protein.
From leucoplasts stems the subtype, proteinoplasts, which contain proteins for storage. They contain crystalline bodies of protein and can be the sites of enzyme activity involving those proteins. Proteinoplasts are found in many seeds, such as brazil nuts, peanuts and pulses.
The cells of the root tubers of the potato plant contain leucoplasts (starch grains). To extract the starch, the potatoes are crushed, and the starch grains are released from the destroyed cells. The starch is then left to settle out of solution or separated by hydrocyclones, then dried to powder.
A plastid is a membrane-bound organelle found in plants, algae and other eukaryotic organisms that contribute to the production of pigment molecules. Most plastids are photosynthetic, thus leading to color production and energy storage or production.
A stromule is a microscopic structure found in plant cells.Stromules (stroma-filled tubules) are highly dynamic structures extending from the surface of all plastid types, including proplastids, chloroplasts, etioplasts, leucoplasts, amyloplasts, and chromoplasts.
Like most leucoplasts, elaioplasts are non-pigmented organelles capable of alternating between the different forms of plastids.The elaioplast specifically is primarily responsible for the storage and metabolism of lipids, [5] among these roles, recent studies have shown that these organelles participate in the formation of terpenes and fatty acids.
Leucoplasts are non-pigmented plastids and helps in storage of nutrients. [12] Structures outside the cell membrane. Many cells also have structures which exist ...
