Among the following, which organelle has an outer membrane in it?
Correct answer: B. Mitochondria
- A. Cell Membrane
- B. Mitochondria
- C. Lysosome
- D. Vacuole
Explanation
Mitochondria is an organelle that has a double membrane around it. The outer membrane surrounds the whole organelle. It has many protein-based pores that are big enough to allow the passage of ions and molecules. Inner membrane of mitochondria has Fo-F1 particles located towards the matrix side. Between the outer and inner layers, there is intermembrane space.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
