The leucoplast stores starches and oils.
Plant organelles that store starches or lipids are called plastids, but not the chloroplasts.
Plastids.
Starches are produced by plants to store energy from the sun. When we consume starches, our bodies can use them for energy, too. Starch, however, does not have any nutritional benefits and is dispensable from the human diet.
In their stem and leaves only
Organelles that store starches in plants include amyloplasts, while lipid storage organelles are called oleosomes. Lipids are also present in the membranes of organelles such as the endoplasmic reticulum and the chloroplasts.
Potatoes store carbohydrates as starches, mainly in the form of amylose and amylopectin. These starches act as an energy reserve for the plant and are converted into sugars when needed for growth or energy.
The plant organelles that store starches are called amyloplasts, while those that store lipids are called elaioplasts. Organelles containing pigments are called plastids, with chloroplasts containing chlorophyll (green pigment) and chromoplasts containing other colored pigments such as carotenoids.
Leucoplasts are generally colourless. Iodine stains starches blue, so this is probably what you're seeing. Leucoplasts are a type of plastid, meaning they store and produce things in cells. Leucoplasts specifically tend to store starches which is why iodine turns them blue. Hope this helps!
Algae store starches primarily in specialized structures known as pyrenoids, which are found within their chloroplasts. These pyrenoids serve as sites for carbon fixation and starch synthesis. Additionally, some algae may store starch in the form of granules located in the cytoplasm or within the chloroplasts themselves. This storage allows algae to utilize the energy when needed for growth and metabolism.
Starches are used for energy
starches and monosaccharides are carbohydrates, and monosaccharides make up starches, which is a polysaccharide.
plenty of the starches are found in maize
