what is the function of granum and stroma
Answers
Answer:
The grana of chloroplast consists of pigment system made up of chlorophyll-a, chlorophyll-b, carotine and xanthophyll while the stroma contains relevant enzymes required for photosynthesis as well as DNA, RNA and cytochrome system.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.

Answer:
Explanation:
Granum: A granum is a coin-shaped stack of thylakoids, which are the membrane-like structures found inside the chloroplasts of plant cells. Photosynthesis, or the process by which plants make their own food, occurs in the chloroplasts. Grana, or groups of granum, are connected by way of stromal thylakoids.
Stroma: Stroma (from Greek στρῶμα 'layer, bed, bed covering') is the part of a tissue or organ with a structural or connective role. It is made up of all the parts without specific functions of the organ - for example, connective tissue, blood vessels, ducts, etc.
