Cell Structure Flashcard

Front

In an isotonic solution, the cell is at __________.

Back

Equilibrium

Front

In the diffusion process, what happens to the dye molecules over time?

Back

They spread evenly throughout the liquid.

Front

What is one of the main functions of the cell membrane?

Back

It controls what can exit and enter the cell.

Front

What is the process called when a dye spreads evenly throughout a liquid?

Back

Diffusion

Front

What is the process called that allows glucose to enter and exit red blood cells?

Back

Facilitated diffusion.

Front

Define isotonic solution.

Back

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

Front

What is hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of the cell, causing the cell to lose water.

Front

What is hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell, causing the cell to gain water.

Front

What is osmosis?

Back

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 active transport?

Back

The process of moving molecules across a cell membrane from a region of lower concentration to a region of higher concentration, using energy.
