Cell Transport

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to enter the cell, potentially leading to swelling or bursting.

Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration across a semi-permeable membrane.

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to leave the cell, leading to shrinkage.

Active transport is the process by which cells use energy to move materials against their concentration gradient, from low to high concentration.

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

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

Facilitated diffusion is a type of passive transport that uses transport proteins to help move substances across a cell membrane.

Cell membranes regulate the movement of substances in and out of the cell, maintaining homeostasis and allowing for selective permeability.

In a hypotonic solution, water enters the cell, which may cause the cell to swell and potentially burst.

In a hypertonic solution, water leaves the cell, causing the cell to shrink and lose turgor pressure.
