Humidity and wind speed are two variables that influence the rate of transpiration. In what way do these two factors change the concentration gradient of water molecules between the leaf interior and the surrounding atmosphere?
- AHigh humidity lowers concentration gradient; high wind speed raises concentration gradient.
- BHigh humidity raises concentration gradient; high wind speed raises concentration gradient.
- CHigh humidity lowers concentration gradient; high wind speed lowers concentration gradient.
- DHigh humidity raises concentration gradient; high wind speed lowers concentration gradient.
