Verified step by step guidance

Understand the function of the nuclear lamina: The nuclear lamina is a dense fibrillar network inside the nucleus of eukaryotic cells. It provides structural support and helps maintain the shape of the nucleus.

Identify the role of the Golgi apparatus: The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles. It does not play a role in maintaining the shape of the nucleus.

Consider the function of mitochondria: Mitochondria are the powerhouses of the cell, responsible for producing ATP through cellular respiration. They do not contribute to the structural integrity of the nucleus.

Evaluate the role of the endoplasmic reticulum: The endoplasmic reticulum (ER) is involved in protein and lipid synthesis. While it is connected to the nuclear envelope, it does not directly maintain the shape of the nucleus.

Conclude that the nuclear lamina is the organelle responsible for maintaining the shape of the nucleus, as it provides structural support and stability to the nuclear envelope.
