Lesson outcome
I can explain the effects of environmental factors on the rate of water uptake by a leafy shoot.
Show transcript
Compare data on rate of water uptake by a plant at a range of light intensities.
Identify a pattern or trend in the data.
Higher light intensity increases transpiration rate as stomata open wider to increase gas exchange for photosynthesis.
Increased temperature and air movement also increase the rate of water uptake.
Higher temperature and air movement increase transpiration due to increased diffusion of water out through stomata.
