The total uptake rate between foliage and root system will determine plant growth rate uptake in terrestrial plants is usually driven by transpiration to the mitotic (growth) site our aquatic stem plants (cabomba, anacharis, bacopa, etc) have terminal meristems like trees. The rate of transpiration is affected by a number of environmental factors as well as leaf morphology different environmental factors change the rate of diffusion of water vapor and also affect the opening and closing of stomata.
