Isotonic

Definition: a solution with the same water concentration as inside a the cell.

Net Movement: there will be no net movement, because the water is at an equilibrium.

Effect: the cell will remain the same / undamaged.

Hypertonic

Definition: a solution that has a lower water concentration in comparison to the inside of the cell.

Net Movement: water will move out of the cell, because of osmosis (water moves from a high water concentartion, in the cell, to a low concentration, the solution.)

Effect: on animal cells, the cell will shrik, but no damage is caused. due to the cell wall in a plant cell, the cell will just become flaccid.

Analogy:

  • Imagine a kid who's hyper (high water concentration in the cell)
  • and wants to run around and let their energy out (water moves from in the cell to the solution)
  • They'd eventually get tired (the cell shrinks / becomes flaccid)

Hypotonic

Definition: a solution that has a higher water concentration compared to the inside of a cell.

Net Movement: water moves into the cell, because of osmosis (water moves from a high water concentration, the solution, to a low concentration, the cell.)

Effect: on an animal cell, the cell will burst, causing damage. Due to the cell wall in a plant cell, the cell will just become turgid.

Analogy:

  • Imagine a blowfish (low concentration in the cell)
  • who's taking in air (osmosis)
  • and eventually... explodes (cell bursts/ becomes turgid)

It's easy and simple to understand

Pasta Martin Ssempa once said: "They use bananas, carrots and cucumbers and put it inside their private parts!" But I say "They use Isotonic, Hypertonic and Hypotonic to commit ****** in Uganda. In Africa, that is so baddd"
