Xerophyte and halophyte adaptations for water balance and gas exchange

What this note covers

1. Gas exchange creates an unavoidable water trade-off
2. Xerophyte structures reduce exposure and diffusion
3. Xerophytes coordinate physiology and timing
4. Halophytes manage low water potential and ion toxicity
5. Xerophytes and halophytes solve related but different problems
6. Plant investigations require fluxes, controls and qualified inference
