Movement of Substances

Flashcards covering key concepts about the movement of substances, specifically diffusion and osmosis.

Diffusion is the net movement of particles from a region of concentration to a region of concentration.

Lower; higher

In osmosis, water molecules move from a region of water potential to a region of water potential through a partially permeable membrane.

Higher; lower

The rate of diffusion is affected by factors such as concentration gradient, diffusion __, and surface area to __ ratio.

Distance; volume

A __ solution has the same water potential as another solution.

Isotonic

In a hypertonic solution, plant cells will experience net movement of water molecules __ the cell.

Out of

The term for the pressure exerted by water in the vacuole on the cell wall in plants is called __ pressure.

Turgor

When red blood cells are placed in a hypotonic solution, they will __ due to the net movement of water inside the cell.

Expand and burst

During diffusion, particles will continue to move until they reach __ equilibrium.

Uniform

The movement of water molecules in osmosis occurs through a __ permeable membrane.

Partially

The greater the surface area to volume ratio of a cell, the __ the rate of diffusion.
