Ethanol is a type of alcohol and alcohol breaks apart the weak hydrogen bonds in the lipid bilayers of cell membranes, which in turn, means it's denaturing. Once a membrane denatures, it no longer has a function so it becomes more permeable and it's less selective.
Yes.
Yes
It is semi permeable [ the cell membrane]
Unwanted substances could get in, potentially destroying the cell and membrane.
the cell wall
THE cell membrane is selectively permeable whereas the cell wall is fully permeable ..
Cell membrane is selectively permeable membrane, therefore it allows selective molecules to be taken in by the cell and excludes others. Whereas cell wall is permeable in nature and does not inhibit the intake of many molecules what the cell membrane does.
The cell membrane is semi-permeable.
in plants cell surface membrane! and in animal plasma membrane!
Animal cell membranes are a semi-permeable membrane.
It is semi permeable [ the cell membrane]
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.
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
it is not selective permeable. - Cell membranes are selective permeable. Cell walls are fully permeable - which means that it allows all substances/molecules to pass in and out of the cell. It is located outside of the membrane.
Plasma membranes are selectively permeable.
no
The cell membrane is selectively permeable.
