Which of the following organelle is associated with a single membrane?
Correct answer: B. Endoplasmic Reticulum
- A. Mitochondria
- B. Endoplasmic Reticulum
- C. Nucleus
- D. Chloroplast
Explanation
The endoplasmic reticulum (ER) is a single-membrane-bound organelle. This means that it is surrounded by a single layer of phospholipids. The ER is a network of interconnected tubules and sacs that is found in the cytoplasm of eukaryotic cells. It is the largest organelle in the cell, and it can account for up to 20% of the cell's volume. All the other organelles given in the options are surrounded by a double membrane.
