Semi-Circular canals
The fluid region of the chloroplast is known as the stroma. It is a semi-liquid substance that fills the space between the thylakoid membranes and surrounds the thylakoid stacks called grana. The stroma contains enzymes and other molecules that are involved in the synthesis of carbohydrates during the process of photosynthesis.
