WebGram-positive bacteria have a thick absorbent cell wall with a cell membrane beneath, and gram-negative bacteria have a thin cell wall sandwiched between two cell membranes. The cell membrane (also … WebThe reason for the thick cell walls is to provide less resistant to the flow of the solution mainly the water and other dissolved nutrients. The vessels of the xylem contain mature non-dividing secondary cell walls in order to give the strength and mechanical support to the xylem and hence to conduct the water transportation smoothly.
