Question

Explain permeability membrane explain with suitable example

Answer 1

There are mbranes which have different capabilities of letting things pass from them that's called the permiability of the membrane.
They are typically made of thin flat epithelial cells. Some have glands for secretion .
There are these membrane called semipermeable membrane and impermeable mbranes . The semipermeable membrane as the name suggests only allow some selective molecules or ions to pass but impermeable do not allow things to pass through them
There is one more .... freely permeable membrane which allows most of the things to pass through them .
