Adiabatic wall Diathermic wall i. An ideal wall or partition separating two systems such that no heat exchange can take place between the systems is called adiabatic wall. A wall that allows exchange of...

B) plasma membrane

Correct option is D) Cellulose

The formation of the new cell wall begins with the formation of a simple precursor, called the ‘cell-plate’ that represents the middle lamella between the walls of two adjacent cells.

A) heavy truck

(C) Phellem Cork cambium (phellogen) cuts off cells on both the sides. The outer cells differentiate into cork or phellem. The cork is impervious to water due to suberin deposition in...
