Plasma Membrane Flashcard

Front

What happens to a cell when it is placed in a hypertonic solution?

Back

The cell shrinks due to the loss of water.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a high concentration of solute outside the cell compared to the inside.

Front

What is homeostasis in the context of cells?

Back

Homeostasis is the state when there is an equal amount of substances on both sides of the cell membrane.

Front

What happens to a cell in a hypotonic solution?

Back

The cell swells and may burst due to the influx of water.

Front

What is a hypotonic solution?

Back

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

Front

What is dynamic equilibrium?

Back

Dynamic equilibrium is another term for homeostasis, where the concentrations of substances are balanced.

Front

What is an isotonic solution?

Back

An isotonic solution has equal concentrations of solute inside and outside the cell.

Front

How does osmosis affect cell size?

Back

Osmosis can cause cells to shrink in hypertonic solutions and swell in hypotonic solutions.

Front

What role does the plasma membrane play in osmosis?

Back

The plasma membrane regulates the movement of water and solutes in and out of the cell.

Front

What is the significance of solute concentration in cellular environments?

Back

Solute concentration affects the direction of water movement and the overall health of the cell.
