Show Answer

Correct Answer � C Explanation

Ans: C. cis-Golgi network

• The arrow on the electron micrograph is pointing on the Golgi Network.
• In all eukaryotes, each Golgi cisternal stack has a cis entry face and a trans exit face.
• The end marked is towards the side of the Nucleus, hence the cis-side of the Golgi.
• Medial cisterna is a part of cis-Golgi network, seen only in some Protistans.
