Question

Hi. Help needed .

I'm stuck on this question ;

Give at least five examples of the following ;
1.Permeable membranes
2.Impermeable membranes
3. Semipermeable or selectively permeable

Answer 1

Permeable membranes allow anything to pass through.

Impermeable membranes have a poor permeable rate or nothing can pass through.

Semipermeable membranes select or allow only certain substances to pass through.

Step-by-step explanation:

Permeable Membranes:

• Window screen - can pass water and air through 100%
• Mesh - can pass water and air through 100%

Impermeable Membranes:

• Clay - permeability rate is extremely low, and water cannot pass through
• Ziplock bag - nothing can come in or out

Semipermeable Membranes:

• Plant and Animal cell membranes (lipid bilayer) - only certain substances can pass through, like soluble vitamins
• Cell Organelle Membranes - only certain substances can pass through the mitochondria, for example
