Question

Cell organelle covered by a single unit membrane is

• A. Glyoxysome
• B. Lysosome
• C. Peroxisome
• D. All of the above

Answer 1

The correct option is D All of the above

• Unit membrane refers to the limiting membrane of cells and cellular organelles which is composed of 3-layered structure- an inner lipid layer and two outer protein layers.
  
• This unit membrane surrounds most of the cellular organelles (Golgi apparatus, glyoxysome, lysosomes, peroxisomes etc.).
• Lysosomes, glyoxysomes and peroxisomes are single-membraned cellular organelles.
• So, the correct answer is 'All of the above'.
