Water availability for plants:
Same species, different levels of water availability

How do plants change allocation to roots/shoots during growth? S:R = 1 Shoot mass
Root mass
Trees S:R = 1 Shoot mass
Root mass
The ability to change = "phenotypic plasticity"
Interesting data.... But why is this a "bad graph"?
