How Do Plants Drink Water?
植物是怎么喝水的？
-
Plants take water from soil through their roots.植物通过根部从土壤中吸收水分。
-
Tiny root hairs grab water like little sponges.细小的根毛像小海绵一样吸收水分。
-
Water moves up thin tubes called xylem.水分通过称为木质部的细管向上输送。
-
This happens by capillary action and evaporation.这一过程依靠毛细作用和蒸腾作用完成。
-
Leaves lose water vapor through tiny holes called stomata.叶片通过称为气孔的微小孔洞散失水蒸气。
-
That loss pulls more water upward like a straw.这种散失像吸管一样将更多水分向上拉。
-
Water carries minerals from soil to leaves and stems.水分将土壤中的矿物质运送到叶片和茎部。
-
Without water, plants wilt and cannot make food.缺水时，植物会萎蔫且无法制造养分。
