Answer to Question 1

The water came from the leaf and the glass of water below. Through capillary action,
the xylem in the leaf draws in water that is then released in vapor form through the
stomates. As the water vapor condenses, it forms water droplets on the glass.



Answer to Question 2

The presence of salt in the soil causes water to be lost from the roots. The salt causes
the available water to be much less plentiful in the soil. Through osmosis, the water
moves from an area where it is plentiful (the root) to an area where it is less
plentiful (the salty soil
