plants use sunlight to make glucose from carbon dioxide and water

This process is called photosynthesis. Temperature, carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis.

Photosynthesis requires light energy, presence of chloroplasts, water and carbon dioxide

. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen. (Boundary: Further details of the photosynthesis process are not taught at this grade level.)

While in photosynthesis carbon dioxide and water ..

Every leaf is a solar-powered food factory, producing the food a plant requires from simple ingredients: water and carbon dioxide.

is one of the most important anabolic chemical reactions that allows life to exist on Earth. With water, light energy from the sun, and carbon dioxide from the air, photosynthetic organisms are able to build simple sugars. Organisms that can make their own food are called , and are at the base of the food chain. The basic reaction is:

Respiration also produces waste products including carbondioxide and water, which are the same substances that served as the raw materialsfor photosynthesis.

Light, water, chlorophyll and carbon dioxide are the ..

Photosynthesis is the primary function of the leaves and requires carbon dioxide, water ..

Photosynthesis is a process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules needed for growth. These molecules include sugars, enzymes and chlorophyll.

Light energy is absorbed by the green chemical chlorophyll. This energy allows the production of glucose by the reaction between carbon dioxide and water. Oxygen is also produced as a waste product.

Dioxide + water in the presence of light yields sugars & oxygen

Plants absorb water through their roots, and carbon dioxide through their leaves. Some glucose is used for respiration, while some is converted into insoluble for storage. The stored starch can later be turned back into glucose and used in respiration. Oxygen is released as a by-product of photosynthesis.

Carbon dioxide is needed for photosynthesis - eschooltoday

Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product.

Carbon dioxide in photosynthesis

Photosynthesis, which results in the manufacture of sugars, allows the plant to grow. It consumes luminous energy, water and carbon dioxide. Respiration, on the other hand, consists of the degradation of sugars. It generates the energy needed for the plant’s different activities, such as growth and reproduction. For the plant to grow, the quantity of organic matter produced by photosynthesis must exceed losses due to respiration.

Plants get carbon dioxide from the air through their leaves

The first phase of photosynthesis requires that light fall on the leaf. The chlorophyll that is embedded in the membranes of the thylakoids absorbs luminous energy. This absorption of energy is accompanied by the degradation of water molecules and the release of oxygen. In a second, light-independent phase, the energy absorbed by the chlorophyll is used to transform carbon dioxide molecules into sugar molecules.

This reaction also requires water ..

But remember it takes 30 to 40 years for the tree to absorb all that carbon from the atmosphere. The process of "photosynthesis" takes time. Leaves use sunlight and water to convert CO2 from the atmosphere into sugar that the tree uses to grow and build more wood fiber. The tree's average carbon uptake, therefore, may only be about 200 lbs. of carbon a year.

during the light reactions of photosynthesis.

In respiration energy is released fromsugars when electrons associated with hydrogen are transported to oxygen (theelectron acceptor), and water is formed as a byproduct. The mitochondriause the energy released in this oxidation in order to synthesize ATP. Inphotosynthesis, the electron flow is reversed, the water is split (not formed),and the electrons are transferred from the water to CO2 and in theprocess the energy is used to reduce the CO2 into sugar. Inrespiration the energy yield is 686 kcal per mole of glucose oxidized to CO2,while photosynthesis requires 686 kcal of energy to boost the electrons from thewater to their high-energy perches in the reduced sugar -- light provides thisenergy.
