Question

Which of the following has a single membrane?

• A. Ribosome
• B. Peroxisome
• C. Nucleus
• D. Cytoskeleton

Answer 1

The correct option is B Peroxisome

There are various organelles present within the cell and are classified into three categories based on the presence or absence of the membrane.

Organelles without membrane: Ribosomes and cytoskeleton are non-membrane-bound cell organelles. They are present both in prokaryotic cells and eukaryotic cell.

Single membrane-bound organelles: Vacuole, lysosome, golgi apparatus, endoplasmic reticulum, peroxisome are single membrane-bound organelles present only in a eukaryotic cell.

Double membrane-bound organelles: Nucleus, mitochondria, and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.
