It Is Hard.
Unwanted substances could get in, potentially destroying the cell and membrane.
the cell wall is fully permeable
Plasma membranes are selectively permeable.
The cell would ultimately die because nutrients and other vital materials would not be able to enter the cell and waste and harmful materials would not be able to leave the cell.
No, the cell wall is not a permeable membrane. It acts as a rigid structure that provides support and protection to the cell, allowing certain substances to pass through pores, but it is not freely permeable like a membrane.
The cell would die as it couldn't maintain homeostasis.
It would be easier for harmful substances to enter.
Cell membranes are indeed selectively permeable.
Cell membranes are selectively permeable while cell walls are semi-selectively permeable. Keep in mind that only low level organisms, like plants, have cell walls.
the cell membrane is not completely permeable.This allows substances in and out of the cell and only a few substances could get into the cell.If the cell membrane becomes permeable any substance including the bad ones will get in easily this could destroy the cell.
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
It is Permeable...
