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.
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.
Elaioplasts: storing fats. Proteinoplasts: storing and modifying protein. or Tannosomes: synthesizing and producing tannins and polyphenols. Depending on their morphology and target function, plastids have the ability to differentiate or redifferentiate between these and other forms.
Afzelia africana seeds bearing orange elaiosomes Trillium recurvatum seeds. Elaiosomes (Ancient Greek: ἔλαιον élaion "oil" + σόμα sóma "body") are fleshy structures that are attached to the seeds of many plant species.
Other subtypes of Leucoplasts include amyloplast, and elaioplasts. Amyloplasts help to store and synthesize starch molecules found in plants, while elaioplasts synthesize and store lipids in plant cells.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Many plastids, particularly those responsible for photosynthesis, possess numerous internal membrane layers. In plant cells, long thin protuberances called stromules sometimes form and extend from the main plastid body into the cytosol and interconnect several plastids. Proteins, and presumably smaller molecules, can move within stromules.
One promising area of study on spherosomes comes from rice bran spherosomes. Rice bran is the hard, outer layer of rice, and it contains notably more fat than any other part of rice.
