Correct Answer: Concave

Solution : The correct option is Concave .

The mature face of the Golgi is the concave or transface, which produces Golgian vacuoles. In animal cells, the Golgi apparatus is located near the centrosome-based microtubule organising centre.

The Golgi body has two unique faces: the cis face, which forms a convex shape, and the trans face, which forms a concave shape. The cis face always faces the nucleus, whereas the trans face always faces the plasma membrane. It has a tubular reticulum known as the trans-golgi network.
