Why do plants use carbon dioxide?

Answer 1

To make food

Answer 2

Carbon dioxide is broken down through photosynthesis and reformed (with the addition of oxygen and hydrogen) to form glucose.

Carbon dioxide is absorbed from the environment through the stomata located on the underside of the leaves.

Answer 3

Plants use CO2 in the process of making glucose in cellular respiration. Carbon dioxide is combined with water to create glucose, using the energy from light to power the reaction.

This is the chemical reaction that occurs in the chloroplasts, where chlorophyll molecules become excited by light, releasing an electron in an electron transport chain which is used to make glucose from the raw materials, CO2 and H2O:

6CO2 + 6 H2O + light=C6H12O6 +6O2

Animals don't use CO2. It is a waste product from cellular respiration and it must be excreted by breathing it out through the lungs. The upside is that animals put more CO2 into the atmosphere which is taken in by green plants to make food (glucose), and plants put out O2 as waste, replenishing the atmosphere with oxygen for animals to breathe.

Cellular respiration is essentially the opposite of photosynthesis, and this is the reaction:

C6H12O6=6H2O + 6CO2 + 36 ATP (used by cells for chemical energy)

It is perfect system. Plants use the CO2 waste gas from animal respiration to make glucose for chemical energy for cells and they put out oxygen into the atmosphere. Oxygen is taken in by animals, used to break down glucose to make ATP for energy for cellular processes, and giving out CO2 which plants take in for photosynthesis.

Answer 4

Plants use carbon dioxide during photosynthesis to make glucose, their primary source of energy. Carbon dioxide is also a key building block for plant growth as it is incorporated into carbohydrates, proteins, and other organic compounds through photosynthesis.

Answer 5

They use carbon dioxide to make food
The basic building blocks of the sugars plants make through photosynthesis that they use for energy and building materials.

Answer 6

they use it when the CO2 goes in they let go and soon for water too

Answer 7

It combines it with 6 molecule of water to produce glucose and oxygen.

Answer 8

the same way we use oxygen
