What is the cis phase of the Golgi apparatus?

The cis-phase, also known as the cis-Golgi network, is the initial section of the Golgi apparatus closest to the endoplasmic reticulum and facing the cell's nucleus. Its primary function is to receive and sort newly synthesized proteins and lipids from the endoplasmic reticulum, preparing them for further modification and transport through the Golgi apparatus. Therefore, the correct answer is the entry phase.
