HORTICULTURE

Detailed explanation-1: -The stroma is the space outside the thylakoid membranes, as shown in Figure below. This is where the reactions of the Calvin cycle take place. In addition to enzymes, two basic types of molecule s-pigments and electron carriers – are key players in this process and are also found in the thylakoid membranes.

Detailed explanation-2: -These thylakoids are arranged in stacks. A stack of thylakoids is called a granum. The region outside of the thylakoids, but inside the chloroplast is called the stroma.

Detailed explanation-3: -5. The stroma is the fluid portion of the chloroplast located outside the thylakoids.

Detailed explanation-4: -The inner membrane surrounds a large space called the stroma, which is analogous to the mitochondrial matrix and contains many metabolic enzymes. Like the mitochondrion, the chloroplast has its own genome and genetic system. The stroma therefore also contains a special set of ribosomes, RNAs, and the chloroplast DNA.
