A
Structure X is not living, and structure Y is living.
B
Structure X can be found in some human cells, and structure Y can be found in some plant cells.
C
Structure X is only found in plant cells, and structure Y is found in plant and animal cells.
D
Structure X is semipermeable, and structure Y is selectively permeable.

What does it mean for a membrane to be selectively permeable?

A
Only certain molecules are allowed to pass through.
B
The membrane is rigid and only allows water to pass through.
C
All types of molecules are able to pass into the cell.
D
The membrane is rigid and nothing can enter or leave the cell.
