Oxygen from carbon dioxide, and hydrogen from water, enter through the leaves and roots, and are used to make glucose
Carbon dioxide and water
Glucose is made up of carbon, hydrogen, and oxygen atoms. The molecular formula of glucose is C6H12O6, meaning it is composed of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms.
Plants use carbon dioxide and water to make glucose molecules through the process of photosynthesis. Carbon dioxide is taken in from the atmosphere through tiny pores in the leaves called stomata, and water is absorbed from the soil through the plant's roots. These compounds are converted into glucose with the help of sunlight and chlorophyll.
Six carbon dioxide molecules (CO2) are required to create one glucose molecule (C6H12O6) because carbon dioxide has one carbon per molecule, while glucose molecules have six carbons.
Each glucose molecule contains 6 carbon atoms. Thus we need 18 molecules of CO2 to make 3 molecules of glucose.
They use it to make reactions with CO2 molecules to form the carbohydrates.
Inorganic molecules are usually defined as any molecule that doesn't contain the element carbon. There are some exceptions, such as carbon dioxide, which is usually defined as inorganic, even though it contains carbon and is a product of some biological reactions.
They make molecules. Molecules are a bunch of Atoms together.
Plants use light energy to make glucose.
It would be more accurate to say that glucose molecules are converted to starch for storage. To make starch, the glucose units join together in a long chain, like beads on a necklace. In order to form the links, each glucose must drop a few atoms so the whole glucose is not present in the starch.
Plants need water to make glucose. Glucose is a sugary substance that plants make. Glucose is the food that plants need to live. So yes, plants do need water.
The process in which the sun is used to make energy rich molecules is called Photosynthesis. This process uses carbon dioxide, water and energy collected from the sun, to produce glucose molecules and oxygen gas. This process happens in plants and is the plant's main source of energy.
