Cell Transport

Front

What is the term for a solution where the concentration of solutes is equal inside and outside the cell?

Back

Isotonic solution

Front

What happens to a cell placed in a hypotonic solution?

Back

The cell expands and may burst (lyse) due to water influx.

Front

Define hypotonic solution in relation to solute concentration.

Back

A hypotonic solution has a lower solute concentration outside the cell compared to inside.

Front

What is the process called when particles move from an area of lower concentration to an area of higher concentration?

Back

Active transport

Front

What type of transport uses energy to move substances against their concentration gradient?

Back

Active transport

Front

What is the role of membrane pumps in active transport?

Back

Membrane pumps use transport proteins to move molecules across the cell membrane.

Front

What is the term for a solution with a higher solute concentration outside the cell?

Back

Hypertonic solution

Front

What occurs to a cell in a hypertonic solution?

Back

The cell shrinks due to water moving out of the cell.

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between passive and active transport?

Back

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