cell walls are semi-permeable, that is, they selectively permit only certain things through.
The plasma membrane, also known as the cell membrane, functions similarly to the cell wall by providing structure, protecting the cell, and regulating what enters and exits the cell. It is a phospholipid bilayer that surrounds the cell and maintains its integrity.
A plastic ziploc bag. It allows certain things to permeate the plastic, and other things not to.
nothing A semipermeable membrane
All cells have a cellular membrane which performs selective transport. Plant cells also have a rigid cell wall which helps them to maintain their shape.
A barrier
POSSIBLY THE INTER MEMBRANE SPACE OR JUST THE MEMBRANE
nothing A semipermeable membrane
Homeostasis is maintained through the plasma/cell membrane. The cell membrane performs osmosis to do so
A membrane bound organelle is a membrane bound structure that performs a very specific function within the cell. For example - nucleus, mitochondria, endoplasmic reticulum, golgi apparatus.
yes it is found in prokaryotes as it has no membrane to cover it and the prokaryotic cell or prokaryotes lack just membrane bounded organelles and it performs the same function as in eukaryotes
Well your skin is an organ, yep it is. Your skin acts as a protector or a barrier from outside harm. A Plasma membrane also performs the same function.
