Answer:
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.
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
