- Temperature changes and plants
- Plants have to balance WATER LOSS and cooling v heat buildup and WATER CONSERVATION
- Plant changes are STRUCTURAL and PHYSIOLOGICAL

- Transpiration
- STOMATA open
- Water loss decreases internal temperature
- Risk of dehydration due to water loss
- Therefore In excessive heat -stomats will close
