why is carbon dioxide needed for photosynthesis

Carbon dioxide, water and light are all needed for photosynthesis to take place.

Photosynthesis is simply the process by which plants take up carbon dioxide to produce simple carbohydrates (glucose). Photosynthesis is a wondrous and yet simple chemical reaction that occurs when plants use sunlight, water and carbon dioxide to make energy-packed food molecules. Carbon dioxide is needed for photosynthesis to produce sugar that then will feed the plant. Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.

Carbon dioxide is consumed during the carbon-fixation part of photosynthesis (the so-called “dark reactions”). Read this: 5 Simple Remedies For Snoring. Using the energy of the sunlight, carbon dioxide (CO 2) and water are converted into … Carbon dioxide in photosynthesis. plural: stomata) The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf. The rates of these reactions can be increased somewhat by increasing the carbon dioxide concentration. The carbon dioxide enters the leaves of the plant through small pores called stomata. Photosynthesis - Photosynthesis - Carbon dioxide: Included among the rate-limiting steps of the dark stage of photosynthesis are the chemical reactions by which organic compounds are formed by using carbon dioxide as a carbon source. Carbon dioxide is present in the air in concentrations of 330 ppm (parts per million) or 0.03 per cent, and can diffuse into the leaf through the stomata. It can therefore be concluded that, carbon dioxide is necessary for photosynthesis.

Plants pull water from their roots and absorb molecules of atmospheric carbon dioxide to gather the necessary ingredients for … This process uses light (the sun rays) to break down the carbon dioxide in the air to oxygen.

The hydrogen equivalents are used during the dark reactions to reduce the carbon dioxide to carbohydrates. Water iscarried to the leaf by xylem vessels and passes into the mesophyll cells by diffusion and reaches the chloroplasts. This also allows the oxygen produced in photosynthesis to leave the leaf easily. Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. Once the carbon dioxide enters the plant, the process begins with the help of sunlight and water. During the “light reactions”, oxygen is released, which is derived from water. Plants extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves. The photosynthesis of plants is one of nature's many wonders. (singular: stoma. It occurs in the leaves in two stages known as light and dark stages. CO2 or carbon dioxide is needed in larger doses for plants and grass need a smaller amount of CO2.
Carbon dioxide needed for photosynthesis enters from the air into the leaf through the stomata in its surface, and then diffuses into the mesophyll cells and reaches the chloroplasts.

Carbon dioxide gas moves ten thousand times faster in air than it would in solution through the roots.

To investigate if a plant needs carbon dioxide for photosynthesis, we need to create conditions for the plants where carbon dioxide is present in one test and absent in another. -101
