When plant and animal cells are put into different liquids, they act in different ways because of their special structures. Let’s make it simple to understand:

1. Isotonic Solution:

   • In an isotonic solution, the amount of dissolved stuff (solutes) is the same inside and outside the cell.
   • This means water moves in and out of the cell equally.
   • Example: Both plant and animal cells keep their shape and size since nothing changes too much.

2. Hypotonic Solution:

   • In a hypotonic solution, there is less dissolved stuff outside the cell than inside.
   • Animal Cells: They can swell up and even burst because they don’t have a hard outer wall.
   • Plant Cells: They fill up with water and become firm, but the tough cell wall stops them from bursting. This firmness helps plants stay strong.

3. Hypertonic Solution:

   • In a hypertonic solution, there is more dissolved stuff outside the cell than inside.
   • Animal Cells: They shrink and change shape because water is leaving the cell.
   • Plant Cells: They lose water, and the cell membrane pulls away from the cell wall, causing the plant to droop.

Understanding how cells react to different liquids helps us learn about important processes like osmosis. It also shows us why plants and animals live and grow in different ways!
