Cell Transport

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is osmosis?

Back

Osmosis is the process where water molecules move through a semipermeable membrane from an area of high water concentration to an area of low water concentration.

Front

What happens to a cell in an isotonic solution?

Back

A cell in an isotonic solution will stay the same size because the concentration of solutes is equal inside and outside the cell.

Front

What occurs when a cell is placed in a hypertonic solution?

Back

When a cell is placed in a hypertonic solution, water moves from inside the cell to the outside solution, causing the cell to shrink.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their gradient.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What is a semipermeable membrane?

Back

A semipermeable membrane allows certain molecules to pass through while blocking others, facilitating selective transport.

Front

What is the role of the cell membrane in transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis through various transport mechanisms.
