- HOW WORKS?
- water enters cell, volume
vacuole increases
- pushes cytoplasm outwards
against cell wall when stretches
- cell wall resists being stretched
and pushes back against cytoplasm
with opposing force
- when cell takes in as much water as
it can, contents cell pushing against cell
wall with MAX force = TURGID
