Which of the following is common to both ER and Golgi apparatus?
a. Both are double membrane bound
b. Both have cisternae
c. Both contain their own DNA
d. Both are semi-autonomous organelles

Dear Student,

Ans. b) Both have cisternae

 A cisterna (plural cisternae) refer to a flattened membrane disk that makes up the Golgi apparatus.
A typical Golgi has anywhere from 3 to 7 cisternae stacked upon each other like a stack of dinner plates, but there are usually around 6. The cisternae carry Golgi enzymes to help or to modify cargo proteins traveling through them destined for other parts of the cell. 

The Endoplasmic reticulum also contains flattened tube-like structures called Cisternae.
