Plant Environment: Water. Water makes up 80-90% of herbaceous and 50% of woody plants. Water is important to plants. Water critical for plant growth (photosynthesis: 6CO 2 + 6H 2 O ---> C 6 H 12 O 6 + 6O 2 ). Water needed to obtain nutrients from soil (nutrients dissolved in water).
(Symptoms same as lack of water…why?)
