Answer #1

Facilitated diffusion occurs down the concentration gradient with the the help of transporter.So this is possible even in case of non-living cell.

Diffusion occurs down the concentration gradient .So this is also possible in case of non-living cell.

Filtration also does not require living cell.

Osmosis requires a semipermeable membrane.So it does not require living cell.

Active transport occurs against the concentration gradient using cellular energy.So this is possible only in a living cell.

So answer is the last option.

a) Sarah and Joe are fighting about cell membranes. Sarah thinks that the only way something can get through a cell membrane is through active pumps. She states that it is the flow from higher to lower concentration with a little sugar that moves things across the membrane. Joe says that it moves through Diffusion, and is the flow from low to high. Who is right? ​​ Support your reason by talking about Active versus Passive movement across a membrane....
