AThe organelles 'e', 'h', 'g' and 'i' are membranebound structures which function in close coordination with one another.
B'f' organelle is responsible for the synthesis of fats inside the cells and it stores Ca2+ for release during muscle contraction.
C'a' and 'b' are selectively permeable membranes.
D'j' is the site for protein synthesis. It allows hereditary message from 'd' to get translated into proteins.
