Rough endoplasmic reticulum
In actively secreting cells, the RER is very extensive and consists of large numbers of interconnecting, flattened sacs or cisterns. Also visible in this field is the nuclear envelope showing ribosomes on the cytoplasmic surface of the outer nuclear membrane. Mitochondria and lipid droplets are also present. 40,000x
