Stroma (from Greek στρῶμα 'layer, bed, bed covering') is the part of a tissue or organ with a structural or connective role. The stroma plays a crucial role in the light-independent reactions as well as the light-dependent reactions of photosynthesis. Thylakoids - Floating in the stroma is a collection of sacks containing chlorophyll called the thylakoids. Carbon Fixation. Stroma definition is - a compact mass of fungal hyphae producing perithecia or pycnidia. Within the stroma, there is a second membrane system called the thylakoid membrane, which consists of disc-shaped sub-structures, arranged into stacks called grana. Learn Plant Cell Organelles.

CallUrl('www>interactive-biology>comblogspot>hu<2008<03html',0), (Left) Evidence that there may have once been liquid water on the surface of mars. Chloroplast has an envelope of two membranes surrounding a dense fluid which is called the stroma. The term “stoma” comes from the Greek word for “mouth.”. Membranous sacs called thylakoids are arranged in stacks called grana. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma..

Initially, the stroma was thought to simply provide support for the pigmented thylakoids. the supporting framework, usually of connective tissue, of an organ, as distinguished from the parenchyma. Semin Cancer Biol. Terms in this set (37) ... sugars are made in the stroma by the enzymes of the Calvin cycle. 2) The fluid filled area of a chloroplast outside of the thylakoid membranes wherein the light-independent reactions (Calvin Cycle and Carbon fixation) of photosynthesis take place. Chloroplasts are surrounded by two membranes. Grana is the site where the light reaction of photosynthesis takes place. They utilize the products of the light reactions, ATP and NADPH to reduce carbon dioxide and to make glucose and the more complex middle sized biomolecules. Stroma can refer to: 1) The connective supportive framework of a biological cell , tissue , or organ . They occur in the chloroplast ~TildeLink(). The chloroplast DNA chloroplast ribosomes and the thylakoid system, starch granules and many proteins are found floating around the stroma. The intergranal lamellae or stroma lamellae connects all the grana present in the chloroplast. In addition, stroma also consists of non-cellular components such as collagen fibers, glycoproteins and glycolipids that provide the structural framework for the tissue and organ. Stroma (animal tissue), the connective, functionally supportive framework of a biological cell, tissue, or organ (in contrast, the parenchyma is the functional aspect of a tissue).
