Question

The organelle that acts as a supporting skeletal framework of the cell is:

• A. Mitochondria
• B. Golgi apparatus
• C. Endoplasmic reticulum
• D. Nucleus

Answer 1

The correct option is C

Endoplasmic reticulum

The correct option is C

Explanation of the correct option:

1. The organelle that acts as a supporting skeletal framework of the cell is the endoplasmic reticulum.
2. The endoplasmic reticulum provides additional mechanical support to the cell by dividing the fluid content of the cell into compartments.
3. That is why it is considered one of the elements of the cytoskeleton.
4. Because of this reason, the endoplasmic reticulum acts as a supporting skeletal framework.

Explanation of the incorrect options:

Option A:

Mitochondria are responsible for the generation of energy in the form of ATP.

Option B:

Golgi apparatus is a secretory organelle that is involved in the storage, packaging, and secretion of different materials.

Option D:

The nucleus is responsible for storing the genetic material of the cell.

Final answer: The organelle that acts as a supporting skeletal framework of the cell is the endoplasmic reticulum.
