What Are Photosynthesis and Respiration?

Photosynthesis. Otosynthesis is the biological conversion of light energy into chemical energy. Is occurs in green plants, algae, and photosynthetic bacteria. Photsynthesis In Plants

photosynthesis and cellular respiration, both are done by plants.

Photosynthesis and 'inverse respiration' in plants: an inevitable misconception?

Cycle of Photosynthesis and Respiration - VTAide

Environmental scientists recognize that the fundamental source of energy for most life on earth is the sun. Through photosynthesis, plants capture the light and convert it into chemical potential energy. Plants then store the potential energy in the form of (biological matter that fuels nearly every animal on earth).

What Are Photosynthesis and Respiration? - dummies

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.

Now we need to understand how cells can use the products ofphotosynthesis to obtain energy.

Difference between Respiration and Photosynthesis | …

Photosynthesis definition, the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae. photsynthesis in plants

Difference between Respiration and Photosynthesis ..

It is not surprising those results considering that the processes of photosynthesis and respiration are taught in terms of learning the names of the inputs and outputs of those processes without making connections to the transformation of inputs and outputs in terms of energy and matter or comparing both processes (Stern & Roseman, 2004).

Difference between Respiration and Photosynthesis

Respiration consists of a complicated series of chemical reactions. In the first stage, glucose is oxidized, and the chemical potential energy of its bonds is transferred to the chemical potential bonds of an ATP molecule. The ATP molecule can then be transported throughout the cell where its stored energy is used to complete various tasks within the cell. This process releases carbon dioxide gas and water.

Chemically speaking, respiration is photosynthesis in reverse, as you can see in this equation:

Cellular Respiration in Plants - Video & Lesson …

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.

animals only do cellular respiration because they need the enrgy to survive in the wild.

Apart from the food they manufacture, plants also need carbon, hydrogen and oxygen to survive. Water absorbed from the soil provides the hydrogen and oxygen. During photosynthesis, carbon and water are used to synthesize food. They also need nitrate to make amino acids (Amino acid an ingredient for making protein). In addition to that, they need magnesium to make chlorophyll.

In this lesson, we shall learn more about how plants manufacture food (photosynthesis), and learn more about the conditions that must be present for this to happen.

Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.
