Question

State one way the two molecules could differ that would explain the difference in their ability to pass through the artificial plant cell membrane

Answer 1

There are multiple facts that can justify that two molecules shows difference in their ability to pass through a membrane:

- Size and molecular weight  

- Receptors on the membrane and the molecules

- Structure of the membrane

- Membrane affinity

Different molecules have different solubility depending upon the type of molecule and membrane.

Answer 2

Ability to pass through the plant cell

Explanation:

• A cell's prosperity relies upon its capacity to control the entry of atoms over the cell layer. A few atoms can diffuse through the cell layer with no help from the cell. Others need the support of trans membrane proteins to move into or out of the cell.
• Three essential variables decide if a particle will diffuse over a cell film: focus, charge and size.A cell layer contains two layers of phospholipids. Every phospholipid particle has a hydrophilic phosphate head and two hydrophobic lipid tails.
• The heads line up along the inward and external surfaces of the cell film, while the tails occupy the center space. Different kinds of trans membrane proteins give encouraged dispersion or dynamic vehicle for particles that can't inactively diffuse through the cell layer
