Ring in the new year with a Britannica Membership, https://www.britannica.com/science/stroma-in-chloroplast, chloroplast: Characteristics of chloroplasts, cell: Mitochondrial and chloroplastic structure. 3. The … Overview of Stroma In Chloroplast Stroma generally refers to the inner fluid-filled space of the chloroplasts that surrounds the grana and the thylakoids. Chloroplasts are present primarily in the cells of mesophyll tissue inside the leaf. These grana resemble a stack of thylakoid "coins" or "disks." Whereas the aqueous phase of the inner membrane – the stroma contains most of the enzymes required for carbon assimilation. Thylakoids are usually arranged in stacks (grana) and contain the photosynthetic pigment (chlorophyll). The thylakoid consists of the thylakoid membrane and the enclosed region called the thylakoid lumen. In addition to enzymes, two basic types of molecules - pigments and electron carriers – are key players in this process and are also found in the thylakoid membranes. The space outside the thylakoid space is called the stroma. The membranes run through a ground substance or stroma. Stroma is the cytoplasm of the chloroplast which is composed of a transparent liquid, in which thylakoid (grana), sub organelles, DNA, ribosome, lipid droplets and starch grains are present.
