Omolarity and stuff

hypotonic

Low solute concentration and high water concentration compared to another solution

Hypertonic

high solute concentration and low water concentration compared to another solution

isotonic

Balanced solute concentration and water concentration

turgor pressure

the pressure exerted by fluid against a plant cell wall as water enters the central vacuole

Lysed

an animal cell that is swollen and about to burst due to lots of water being let in

Flaccid

a plant cell that is limp because its in an isotonic environment with no net gain of water

Plasmolyzed

a plant cell whose plasma membrane has pulled away from the cell wall because of the lack of water in a hypertonic environment

Osmosis

the net movment of water molecules across a selectively permeable membrane

Osmotic pressure

The minimum pressure needed to prevent water from being pulled out by the solute

Hydrostatic pressure

the pressure exerted by a fluid a rest inside a membrane

Phagocytosis

when a cell surrounds and engulfs large SOLID particles

Passive transport

being able to be moved without ATP for power. This uses potential energy to move

Bulk transport

The process in which large particles are moved into a membrane. Requires ATP

Active transport

the movment of molecules with the help of a protein

Moving from high to low water concentration

water movment

Water comes out of the cell when a solute is added

Hypertonic solution, where the concentration of solute outside the cell is higher than inside, causing water to exit the cell to balance solute concentrations.
