Consider the structural polarity and dimensional characteristics of the Golgi apparatus. Which of the following statements accurately describes its architecture?

  1. Cisternae have a diameter of 0.5 μm to 1.0 μm with convex cis face being the forming face and concave trans face being the maturing face
  2. Cisternae have a diameter of 1.0 μm to 2.5 μm with concave cis face acting as maturing face
  3. Cisternae have a diameter of 0.1 μm to 0.5 μm with convex trans face acting as receiving face
  4. Cisternae are non-parallel flat sacs where cis and trans faces are completely identical in molecular composition

Correct answer · Option 1

Cisternae have a diameter of 0.5 μm to 1.0 μm with convex cis face being the forming face and concave trans face being the maturing face

Explanation

Golgi cisternae are 0.5 μm to 1.0 μm in diameter, arranged parallelly, having a distinct convex cis (forming) face and a concave trans (maturing) face.
