Explanation:
Statement 1: The cisternae in Golgi complex have cis face and trans face.
The Golgi complex is an organelle found in eukaryotic cells that plays a key role in the processing and sorting of proteins and lipids. It consists of a series of flattened membrane-bound sacs called cisternae. These cisternae have two distinct faces - the cis face and the trans face.
Statement 2: The cis face is also called the forming face and the trans face is also called the maturing face.
The cis face of the Golgi complex is the side that is closest to the endoplasmic reticulum (ER), where newly synthesized proteins and lipids enter the Golgi. It is involved in receiving and sorting proteins and lipids from the ER. The cis face is also referred to as the forming face because it is where the Golgi complex receives and forms vesicles containing these proteins and lipids.
The trans face of the Golgi complex is the side that is farthest from the ER. It is involved in packaging proteins and lipids into vesicles that will be transported to their final destinations. The trans face is also referred to as the maturing face because it is where the Golgi complex modifies and matures these proteins and lipids before they are packaged into vesicles.
Conclusion:
Both statements 1 and 2 are correct, but statement 2 is not the correct explanation of statement 1. The cis face and trans face of the Golgi complex are indeed referred to as the forming face and maturing face, respectively, but these terms do not explain the function or location of the two faces. The cis face is where the Golgi complex receives and forms vesicles, while the trans face is where it packages and matures proteins and lipids. Therefore, the correct option is B.

Golgi complex consists of a stack of cisternae which are curved to give definite polarity to the Golgi apparatus. The convex side (forming/cis face) receives vesicles from endoplasmic reticulum. The concave side (maturing /transface) buds off vesicles as secretion.
