    I read this article
    Plants Don’t Convert CO2 into O2 « How Plants Work
    and it lead me to believe that the process of turning water into oxygen in photosynthesis is just coincidental and has nothing to do with making sugars or feeding the plant. Am I right in believing this? Is the water just to keep the plant hydrated?
    By the way, I am an ignorant 13 year old, so please don't hate.

    just give me some fresh apple peel
    and i will be happy
    but hydrogen from water
    is combined with co2
    to make sugar
    a carbohydrate
    this provides the plant
    with much of what it needs

    No, the oxygen is a by-product of releasing electrons from water molecules, which are used to create an electrochemical gradient for use in breaking down carbon dioxide to make sugars.

    Plant ate those sugar and use oxygen to create energy for themselves. In some plant they put carbohydrate in their root and/or in their seed for energy storage.. eg: Potato has it on their root, and Rice has it on their seed.

    People also ate carbohydrate... that's why we ate Potato and Rice.

    No it's not coincidental. All the article is telling you is that people over-simplify when they say that plants absorb CO2 and release O2. They do exactly that. They also produce carbohydrates as part of the process.

    But. It's a process. It's not a single, simple chemical reaction. It's a series of chemical and physical interactions that have that result.
