The descriptions below explain two ways that water is used by plants on a sunny day. 1. In a process called transpiration, some liquid water in leaves changes to water vapor. The water vapor is released into the air through tiny pores in the leaves. This allows more liquid water from the soil to be pulled up the roots and stem to replace water lost from the leaves. II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen and glucose. Based on the above description of transpiration and photosynthesis, which type of change happens to water during each process? In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change. In transpiration, because some of its properties change, water undergoes a chemical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a physical change.

Based on the description provided, the correct answer is:<br /><br />In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.<br /><br />Explanation:<br /><br />1. Transpiration:<br /> - In transpiration, water in the leaves changes from a liquid state to a water vapor.<br /> - This is a physical change, as the water molecules themselves remain unchanged, only their physical state changes from liquid to vapor.<br /> - The water vapor is then released into the air through the tiny pores in the leaves.<br /> - This physical change allows more liquid water from the soil to be pulled up the roots and stem to replace the water lost from the leaves.<br /><br />2. Photosynthesis:<br /> - In photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen and glucose.<br /> - This is a chemical change, as the water molecules are broken down and rearranged to form new chemical compounds.<br /> - The water molecules are no longer in their original form but have become part of the new substances (oxygen and glucose) produced during the photosynthesis process.<br /><br />Therefore, the correct answer is that in transpiration, water undergoes a physical change, while in photosynthesis, water undergoes a chemical change.
