Factors affecting transpiration
Biology · Secondary 4 · Medium · Factors affecting transpiration
After deforestation, the air around exposed shrubs becomes hotter and drier, and wind speed increases. What is the combined effect of these changes on transpiration rate in the shrubs?
- Transpiration rate increases greatly because hotter, drier, windier air removes water vapour faster.
- Transpiration rate decreases because hotter air closes all stomata permanently.
- Transpiration rate is unchanged because only soil water affects it.
- Transpiration stops because wind prevents water from reaching the leaves.
