How Do Plants Drink Water?
植物是怎么喝水的?
-
Plants take water from soil through their roots.
-
Tiny root hairs grab water like little sponges.
-
Water moves up thin tubes called xylem.
-
This happens by capillary action and evaporation.
-
Leaves lose water vapor through tiny holes called stomata.
-
That loss pulls more water upward like a straw.
-
Water carries minerals from soil to leaves and stems.
-
Without water, plants wilt and cannot make food.
