Why humans not have cell wall or guard cell
Answers & Comments
DavidOtunga
Cell wall is absent in humans because the skin itself is a great physical barrier which also helps protect the immune system from 98% cases of being infected by a virus, bacterium, fungi, protozoa and other nonliving or living cells with cause the human body dysfunction. The cell wall is present in plants, fungi and some types of protists. If seen the skin also acts to provide an osmotic balance to the body by providing defence from the alternating concentration which cause in plant cells and animal cells. Thus, the skin can itself maintain and act as a guard cell and a cell wall (also as it is a physiological barrier).
