Cellular Transport Part 2

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What does equilibrium mean in the context of cellular transport?

Back

Equilibrium refers to a state where the concentration of solutes is equal on both sides of a membrane, resulting in no net movement of water.

Front

What happens to a cell in a hypotonic solution?

Back

A cell in a hypotonic solution will swell as water moves into the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution is one where the concentration of solutes outside the cell is lower than the concentration inside the cell, leading to water entering the cell.

Front

What is the effect of a hypotonic solution on cell volume?

Back

Cells placed in a hypotonic solution will gain water and increase in volume.

Front

What is the relationship between water movement and solute concentration?

Back

Water moves from areas of lower solute concentration to areas of higher solute concentration.

Front

What is the term for the pressure exerted by water inside a cell?

Back

Turgor pressure is the pressure exerted by water inside the central vacuole against the cell wall.

Front

How does a cell maintain homeostasis in a hypotonic environment?

Back

A cell can maintain homeostasis by regulating the intake and expulsion of water and solutes.

Front

What is the role of the cell membrane in osmosis?

Back

The cell membrane is selectively permeable, allowing water to pass through while controlling the movement of solutes.

Front

What happens to animal cells in a hypotonic solution?

Back

Animal cells may swell and potentially burst (lyse) in a hypotonic solution due to excessive water intake.
