Plants get the energy to make organic molecules from the sun. Plants are photosynthetic, meaning they are able to harvest the energy in sunlight and perform photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide and water to create glucose and oxygen.

How does a plant get or make organic molecules?
Photosynthesis in plants makes useful organic compounds out of carbon dioxide through carbon-fixation reactions. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce oxygen and organic compounds.

Where did the energy to make organic molecules come from?
After the energy from the sun is converted into chemical energy and temporarily stored in ATP and NADPH molecules, the cell has the fuel needed to build carbohydrate molecules for long-term energy storage.

Where does plants get their energy from?
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

How is energy made from organic molecules?
These organic molecules undergo combustion – they react with oxygen from the atmosphere and produce carbon dioxide. This process typically involves an exothermic reaction which releases heat energy that is converted into usable energy, usually with a heat engine.

Where did organic molecules come from?
All life on Earth is composed of organic molecules—compounds made of long rings or chains of carbon atoms with other elements attached. Today, most of these organic molecules come from the reduction of carbon dioxide (CO2) through several carbon-fixation pathways, such as photosynthesis in plants.

What provided energy to create the first organic molecules?
Oparin and Haldane This theory states that a mixture of organic molecules could form in an oxygen-deprived environment through the random interactions of small molecules, with energy provided by sunlight and lightning.

What converts energy into organic molecules?
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.

How does a plant get these molecules?
Each cell runs on the chemical energy found mainly in carbohydrate molecules (food), and the majority of these molecules are produced by one process: photosynthesis. Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules.

How are organic molecules formed?
Atoms of carbon present in the form of a chain or rings bind with atoms like oxygen, nitrogen, and hydrogen, leading to an organic molecule’s formation. A covalent bond facilitates the binding. Carbon and hydrogen are the main elements that are common in every organic molecule.
