Question

Plant cells are distinguishable from animal cells in containing

• A. Mitochondria
• B. Ribosomes
• C. E.R.
• D. Cell wall

Answer 1

The correct option is D Cell wall

• Presence of cell wall in plant cells makes it distinguishable from an animal cell.
  
• In an animal cell, the outermost membrane is a cell membrane or plasma membrane.
• Whereas, in a plant cell the outermost layer surrounding the cell is a cell wall.
• A cell wall is a tough and flexible structural layer that surrounds cell membrane in plants, algae and most prokaryotes.
  
• The cell membrane is a phospholipid bilayer that are selectively permeable membranes which separate the interior of the cells (cell organelles and cytoplasm) from the outside environment or the extracellular space.
  
• So, the correct answer is 'Cell wall'.
