Question

Compare and contrast diffusion and osmosis and predict the direction of water a solute movement across a selectively permeable membrane.

Answer 1

In diffusion, the molecule is moving from the container with higher concentration into the lower concentration, resulting in a similar concentration between both containers in the end.
But in osmosis, the molecule can't move. The molecule can attract water, so the container with higher concentration will attract more water. This will cause the water to move, not the molecule. The water will move from the container with lower concentration into the higher concentration. The result after the osmosis should be both containers have similar concentration, just like diffusion.

Answer 2

Similarities

Diffusion and osmosis are both examples of passive transport.

They transport substances down a concentration gradient.

Difference

Diffusion is the movement of solute particles down a concentration gradient. Osmosis is the movement of water molecules down a concentration gradient.

FURTHER EXPLANATION

Active and Passive Transport

Passive transport is the movement of particles through a membrane which requires no extra energy. It happens spontaneously because there is an imbalance in the amount of solutes  or difference in concentration inside and outside the membrane. In order to reach equilibrium or a state where the amount of solute or concentration on both sides is the same, some substances have to cross the membrane.

When substances move from a region of high concentration to low concentration, it is said that the substances are moving down a concentration gradient. This process is spontaneous meaning it does not require energy to occur. The opposite is true for active transport which requires additional energy for it to happen.

Movement of Substances

In diffusion, solutes move from a concentrated area to a less concentrated area.

In osmosis, the water molecules move from an area with more water molecules (lower concentration of solutes) to the area with less water molecules (higher concentration of solutes).
