Question

a semipermeable membrane allows larger molecules to pass through but prevent the smaller ones true or false

Answer 1

False Because semipermeable memebrane allows only samller molecules to pass through it.

Answer 2

no . it is false. the reason is the plasma membrane is selectively permeable the hydrophobic molecules and small polar molecules can diffuse through the lipid layer but ions and larger polar molecules cannot. integral membrane proteins enable ions and larger molecules to pass through the membrane by active or passive transport.    hope this helps...
