Study the diagram of the selectively permeable membrane and solute particles below.

Based on the principles of diffusion, in which direction and manner is the indicated solute particle most likely moving?
A.
into the cell by passive transport
B.
out of the cell by passive transport
C.
out of the cell by active transport
D.
into the cell by active transport

Based on the diagram of the selectively permeable membrane and solute particles, the solute particle indicated is most likely moving out of the cell by passive transport. The solute particle is moving from an area of higher concentration (inside the cell) to an area of lower concentration (outside the cell), which is the direction that diffusion occurs. Active transport requires the use of energy to move substances against the concentration gradient, while passive transport occurs spontaneously without the input of energy.
