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

Back

The plant cell will lose water and wilt.

Front

What is homeostasis?

Back

Homeostasis is the process by which organisms regulate their internal environment to maintain stable, constant conditions.

Front

What is transpiration in the water cycle?

Back

Transpiration is the process by which water vapor is released from plants into the atmosphere.

Front

What role do enzymes play in biological systems?

Back

Enzymes act as catalysts to drive chemical reactions forward.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

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 is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to gain water and swell.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
