What is this?
Osmosis is like a special kind of drinking that plant cells do. It's when water moves all by itself from a place where there's lots of water to a place where there's less water, passing through a cell's skin. This helps plants get the water they need to live and stay strong.
Key Parts to Explore
Cell Wall
This is the tough outer layer that gives the plant cell its shape and strength.
Cell Membrane
This is a thin, stretchy skin just inside the cell wall that decides what goes in and out of the cell.
Central Vacuole
This is a big bag inside the cell that stores water and pushes against the cell wall when full.
Water Molecules
These are the tiny particles of water that are constantly moving in and out of the plant cell.
Did You Know?
Did you know that a plant can stand tall and firm all day long just because its cells are full of water, like tiny balloons?
