Solution

The correct option is B Connection between adjacent cells
  • The middle lamella is a layer rich in pectins which cement the cell walls of adjacent plant cells and forms plasmodesmata connections.
  • This pectin-rich layer is made up of calcium and magnesium pectates. 
  • Plasmodesmata are cytoplasmic channels that pass through the cell walls of the plant and few algal cells which help in the transport of substances and communication between the adjacent cells.
  • So, the correct answer is 'Connection between adjacent cells'.
