The carbon in plants come from the carbon found in carbon dioxide (CO2). As plants undergo photosynthesis they draw in water through their roots and carbon dioxide from the air through specialized structures called stomates. So the inorganic carbon in carbon dioxide becomes organic carbon making up the oils, carbohydrates and proteins found in plants.

Where does the carbon come from that plants used to produce carbon dioxide?

From carbohydrates


Where do the carbon atoms come from to produce the certain sugar for photosynthesis?

The carbon atoms used to produce sugars during photosynthesis primarily come from carbon dioxide in the atmosphere. Plants take in carbon dioxide through small openings in their leaves called stomata, and then use the energy from sunlight to convert the carbon dioxide into sugars through a series of biochemical reactions.


Can carbon dioxide come from fire?

Yes. Burning carbon or a carbon compound will produce carbon dioxide.

What elements required by plants does NOT come directly from the soil?

Carbon dioxide (CO2) is an essential element for plants, and it is not directly obtained from the soil. Plants absorb CO2 from the atmosphere during photosynthesis to produce carbohydrates and release oxygen as a byproduct.

Where does most of the air huumans breath come from?

They come from plants. It is a cycle. (Carbon Dioxide and Oxygen Cycle) When you breathe out you realse Carbon Dioxide and the plants sucks it in and relase oxygen and that is what we breathe in.


What do forest need carbon dioxide for?

So that they plants can make glucose for photosynthesis. Glucose is C6H12O6, and the carbon and some oxygen in that equation come from Carbon Dioxide in the plants enviroment.

How come plants produce oxygen even though they need oxygen for respiration?

Plant use carbon-dioxide for respiration. They absorb the carbon molecules and release the oxygen molecules into the air.


Why you need carbon dioxide for photosynthesis-jokes?

The atmosphere didn't literally need the Carbon Dioxide! The main purpose of the Carbon Dioxide is for the plants! Plants needed Carbon Dioxide for their process called photosynthesis to produce their own food and in return they exchange it into Oxygen but for me personally the Carbon Dioxide in our atmosphere is also there to maintain the balance in it.


Where does the carbon dioxde used by plants come from?

Humans inhale oxygen, and breath out carbon dioxide. It is like a cycle.
