Detailed explanation-1: -Stroma is the fluid-filled internal space of the chloroplasts which encircle the grana and the thylakoids. It contains chloroplast DNA, starch and ribosomes along with enzymes needed for the Calvin cycle.

Detailed explanation-2: -: Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. 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.

Detailed explanation-3: -Stroma is the fluid filling up the inner space of the chloroplasts which encircle the grana and the thylakoids. In addition to providing support to the pigment thylakoids, the stroma are now known to contain chloroplast DNA, starch and ribosomes along with enzymes needed for Calvin cycle.

Detailed explanation-4: -Stroma. It is a colourless, alkaline, aqueous, protein-rich fluid present within the inner membrane of the chloroplast present surrounding the grana.

Detailed explanation-5: -These are plastid that contains chlorophyll and converts light energy into stable chemical energy via the photosynthetic process. Stroma is present in chloroplast which surrounds the thylakoid membrane. It is involved in the synthesis of organic molecules with the help of carbon dioxide and water.
