The cornea stroma is composed of dense, regularly packed collagen fibrils arranged in orthogonal layers or lamellae. Free learning resources for students covering all major areas of biology. Fossils like these have subsequently been found all over the world. 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. the tissue forming the ground substance, framework, or matrix of an organ, as opposed to the functioning part or parenchyma. ta (-mə-tə) 1. Stroma Definition – Meaning of Stroma Stroma is the fluid filling up the inner space of the chloroplasts which encircle the grana and the thylakoids. Chloroplasts are surrounded by two membranes. stroma /stroʊmə/ Definitions. On the farm, the feed for chicks is significantly different from the roosters’; ______ not even comparable. Initially, the stroma was thought to simply provide support for the pigmented thylakoids. Stroma is the space within the inner membrane. ‘The endometrial stroma has a framework consisting of reticular fibers and stromal cells.’ Stroma is the site where the dark reaction of photosynthesis takes place.
