Definition. noun, plural: stromata (1) (cell biology) The spongy, colorless matrix of a cell that functionally supports the cell.(2) (anatomy) The supporting framework of an organ, a gland or other structure, usually composed of connective tissue cells, as distinguished from the parenchyma cells or tissues performing the special function of the organ or bodily part.


Stroma commonly refers to the fluid filled inner space of chloroplasts surrounding thylakoids and grana. Initially, the stroma was thought to simply provide support for the pigmented thylakoids. However it is now known that the stroma contains starch, chloroplast DNA and ribosomes, as well as all the enzymes required for light-independent reactions of photosynthesis, also known as the Calvin ...

Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana, stacks of thylakoid, the sub-organelles, the daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma. Photosynthesis occurs in two stages.
