All the following organelles have membranes except

Explanation

• Cell wall

  A non-membrane-bound organelle found in plant, fungi, and some bacteria cells. The cell wall is made of carbohydrates and proteins, and its main function is to protect the cell and provide structure and support. 

• Cell membrane

  Present in all cells, the cell membrane is made of lipids, proteins, and carbohydrates. It's the outermost layer of the cell in animals, and encloses other organelles within. The cell membrane is flexible, metabolically active, and selectively permeable. The cell wall is a non-membrane-bound organelle, while the cell membrane is present in all cells. Therefore, Cell wall has no membrane. Option D.
