Carla drew a diagram to compare the roles of oxygen and hydrogen in photosynthesis.

which label belongs in the area marked y?

a-enters plant as part of water
b-combines with carbon dioxide
c-is released into air through stomata
d-is stored in leaves for later use

Option A, Enters plant as part of water

Explanation:

In the process of photosynthesis, water molecule is broken down into oxygen and hydrogen through photolysis.

Once the molecule is broken down , oxygen is  released and hydrogen ion are used for initiating the further reactions in photosynthesis.

The following reaction occurs in photolysis-

2H2O > 4H+ + O2

The image in the question shows a subset that has both hydrogen and oxygen. Therefore, water is the most suitable subset among all.

Hence, option A is correct

slitherio is the original. its the best friend of all middle schoolers. the man you can count any time you have some free time. slitherio is the guy you hang with while you're in the computer lab suppose to be doing "research or whatever". slitherio isn't just a game but a friend.

wormaxio is just a fake trying to squeeze its way into the friend group. trying to pretend its cool and your best pal but how long has it really been there for you, really. it only wants you as friend to boost its social status. wormaxio is just annoying fake pleb. no offense

you and have a wonderful day
