The descriptions below explain two ways that water is used by plants on a sunny day.

I. 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.

In transpiration, because its physical properties change, water undergoes a physical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a chemical change.

In transpiration, because its chemical properties change, water undergoes a chemical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a physical change.

Hi there, what do you think the answer choice is?  I believe it's D because in both of the transformations, the physical form doesn't change.  It's either the chemical change or the liquid that goes under a change, which doesn't count as the appearance of the plant changing.  I hope this makes sense

Feel free to @ me if you need any more help C:

Politely disagree with the previous response.

As the problem describes, in transportation the water undergoes a physical change from liquid to water vapor (chemically, both of these are still water) whereas in photosynthesis the water undergoes a chemical change and reacts with carbon dioxide to form glucose and oxygen (notice how the products are no longer a form of water)
