what is the function of starch granules in plant cells
energy
title: Granule (cell biology) text: light energy to produce glucose from carbon dioxide. The glucose is stored mainly in the form of starch granules, in plastids such as chloroplasts and especially amyloplasts. Toward the end of the growing season, starch accumulates in twigs of trees near the buds. Fruit, seeds, rhizomes, and tubers store starch to prepare for the next growing season. Granule (cell biology) In cell biology, a granule is a small particle. It can be any structure barely visible by light microscopy. The term is most often used to describe a secretory vesicle. A group of leukocytes called granulocytes contain granules and play title: Plant cell text: Plant cell Plant cells are eukaryotic cells of the types 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 flagellae or centrioles, except in the gametes, and a unique method of cell division involving the formation of a cell plate or phragmoplast that separates the new daughter cells. Plant cells differentiate from undifferentiated meristematic cells (analogous to the stem cells of animals) to form title: Granule (cell biology) text: clathrin-coated transport vesicle. The process of proteolysis, removes the unwanted parts from the secretory granule resulting in mature granules. Insulin granules mature in three steps: (1) the lumen of the granule undergoes acidification, due to the acidic properties of a secretory granule; (2) proinsulin becomes insulin through the process of proteolysis. The endoproteases PC1/3 and PC2 aid in this transformation from proinsulin to insulin; and (3) the clathrin protein coat is removed. Granules are one of the non-living cell organelle of plant cell(the others-vacuole and nucleoplasm). It serves as small container of starch in plant cell. In photosynthesis, plants use title: Starch text: In it, phosphate is internally recycled. The other product, glucose, can be assimilated by a yeast. This cell-free bioprocessing does not need any costly chemical and energy input, can be conducted in aqueous solution, and does not have sugar losses. Starch is synthesized in plant leaves during the day and stored as granules; it serves as an energy source at night. The insoluble, highly branched starch chains have to be phosphorylated in order to be accessible for degrading enzymes. The enzyme glucan, water dikinase (GWD) phosphorylates at the C-6 position of a glucose molecule, close to the chains 1,6-alpha branching title: Granule (cell biology) text: Granule (cell biology) In cell biology, a granule is a small particle. It can be any structure barely visible by light microscopy. The term is most often used to describe a secretory vesicle. A group of leukocytes called granulocytes contain granules and play an important role in the immune system. The granules of certain cells, such as natural killer cells, contain components which can lead to the lysis of neighboring cells. The granules of leukocytes are classified as azurophilic granules or specific granules. Leukocyte granules are released in response to immunological stimuli during a process known as degranulation. The granules
