Term
| Water is absorbed by root system and transported to leaves via _____ because of a pressure difference created by ________ at the leaves through their _______. When evaporation at the leaves decreases at night, water enters the plant through ____ ________. Water enters the roots through _______ because of ____ entering the root. ____ ________ can be so strong that it causes _________, H2O beading on the leaves. |
|
Definition
Water is absorbed by root system and transported to leaves via XYLUM because of a pressure difference created by TRANSPIRATION at the leaves through their STOMATA. When evaporation at the leaves decreases at night, water enters the plant through ROOT PRESSURE. Water enters the roots through OSMOSIS because of IONS entering the root. ROOT PRESSURE can be so strong that it causes GUTTATION, H2O beading on the leaves. |
