If plants don't store up water, how does water leave the plant?
The roots get rid of excess water.
Most plants DO store water.
It is released from the leaves by TRANSPIRATION.
Which picture shows the cuticle?
Remember when you put the celery in the water? What happened to the water level by the next day?
The level dropped A LOT, because the celery sucked it up.
The level stayed the same, because the celery was dead.
The level dropped a little, because of evaporation.
