Why do ribosomes attach to the endoplasmic reticulum
a.) The endoplasmic reticulum provides a greater surface area, thus increasing protein production and secretion
b.)The smooth endoplasmic reticulum packages and transports the proteins made by the ribosomes
c.)The ribosomes store water and the other materials on the endoplasmic reticulum
d.)The ribosomes store proteins that are not used by the endoplasmic reticulum
