Question

1. base your answer to the following question on the information and diagram below and on your knowledge of biology. the diagram shows an experimental setup using an artificial plant cell. molecules a and b are commonly found in plant cells. when tested, it was discovered that molecule a quickly passed through the artificial plant cell membrane. molecule b did not pass through. state one way the two molecules could differ that would explain the difference in their ability to pass through the artificial plant cell membrane.

Explanation:

Molecule A might be small and non - polar (or have a structure allowing diffusion/transport), while Molecule B could be large, polar, or lack a transport mechanism (like a specific channel or being unable to diffuse). For example, A could be a small gas molecule (e.g., $O_2$) and B a large protein, so A passes via diffusion and B can't.

Answer:

One way: Molecule A is small (or non - polar, or uses a transport protein) while Molecule B is large (or polar, or lacks a transport mechanism), so A passes through the membrane and B does not.
