Is there a chemical reaction in photosynthesis?

Is there a chemical reaction in photosynthesis?

The photosynthesis reactions occur in the colored pigments in plant cells. During the photosynthesis process, plants capture light energy and use that energy to make glucose. During respiration, sugar is broken down in a chemical reaction with oxygen.

What type of reaction takes place in plants during photosynthesis?

Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves. Chlorophyll is found in chloroplasts in plant cells , particularly the palisade and spongy mesophyll cells .

What two chemical reactions are required for photosynthesis?

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. Carbon dioxide, water and light are all needed for photosynthesis to take place. Photosynthesis happens in the leaves of a plant.

Do green plants use carbon dioxide in photosynthesis?

For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. During photosynthesis, the oxygen gas produces goes out through the leaves of the stomatal pores.

Why do green plants use carbon dioxide?

Green plants use carbon dioxide for photosynthesis and return oxygen to. Green plants use carbon dioxide for photosynthesis and return oxygen to the atmosphere , even then carbon dioxide is considered to be responsible for green house effect.

How do green plants use carbon dioxide?

Green leaves use energy from sunlight through photosynthesis to chemically combine carbon dioxide drawn in from the air with water and nutrients tapped from the ground to produce sugars, which are the main source of food, fiber and fuel for life on Earth.

How do plants get carbon dioxide from the atmosphere?

Plants absorb carbon dioxide from the atmosphere during photosynthesis. A small amount of carbon dioxide is released during leaf respiration (intake of oxygen), but it is quickly reabsorbed during photosynthesis. So, most carbon dioxide absorbed during photosynthesis is kept out of the atmosphere until the plant dies.

Is carbon dioxide produced by the plants?

Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Do plants put out carbon dioxide at night?

During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.
