C
Sodium

D
Iron

Solution

The correct option is C Calcium
  • The middle lamella is a layer rich in pectins which cement the cell walls of adjacent plant cells and forms plasmodesmata (channels for communication between cells).
  • This pectin-rich layer is made up of calcium and magnesium pectates. 
  • It helps to strengthen the cell wall of two adjacent cells. 
  • Therefore, the main element present in the middle lamella is calcium.
  • So, the correct answer is 'Calcium'.
