Biology · Secondary 4 · Medium · Factors affecting transpiration
A student investigates transpiration using a leafy shoot in a potometer. She repeats the experiment at a higher temperature while keeping all other factors constant. What result should she expect?
- The bubble moves more slowly because stomata close at higher temperature
- The bubble moves at the same speed because light intensity is unchanged
- The bubble moves faster because evaporation from leaves increases
- The bubble stops moving because water expands at higher temperature
