Explanation: The apparatus is made up of flattened single membrane bound sacs called cisternae. Each sac shows a curvature, bunch of sacs are parallely arranged in a stack and the apparatus shows convex curvature towards nucleus.

Do cisternae have membranes?

In cell biology. A cisterna refers to any of the flattened disks of the endoplasmic reticulum and the Golgi apparatus. ... Similarly, the Golgi apparatus is made up of membrane-bound stacks called cisternae.

Does Golgi apparatus have single membrane?

Single membrane-bound: Some organelles are bounded by a single membrane. For example, vacuole, lysosome, Golgi Apparatus, Endoplasmic Reticulum etc. They are present only in a eukaryotic cell. Double membrane-bound: Cell organelles like mitochondria and chloroplast are double membrane-bound organelles.
