Question

Middle lamella represents

• A. Common wall between adjacent cells
• B. Common membrane covering of two adjacent cells
• C. Pore between adjacent cells
• D. Cementing material between two adjacent cells

Answer 1

Answer: (D)

Cementing material between two adjacent cells

• The middle lamella is a layer rich in pectins and forms the plasmodesmata connections between adjacent cell walls.
  
• This layer cements the cell walls of two adjacent plant cells.
• It is the first formed outermost layer (cell plate formed during cell division forms the middle lamella or lamellum).
• So, the correct answer is 'Cementing material between two adjacent cells'.
