How does a plant use carbon dioxide during photosynthesis
It is not just animals that – plants carry out respiration as well. Plants respire all the time because their cells need energy to stay alive, but plants can only photosynthesise when they are in the light.
Plants do breathe - they give out carbon dioxide and absorb oxygen from the air that surrounds them. Their tissues respire just as animal tissues do. Plants, however, do not have lungs or a blood stream, so we cannot say that they breathe in the same way as animals.
How do plants use carbon dioxide? | Socratic
In plants, photosynthesis occurs mainly within the . Since photosynthesis requires carbon dioxide, water, and sunlight, all of these substances must be obtained by or transported to the leaves. Carbon dioxide is obtained through tiny pores in plant leaves called stomata. Oxygen is also released through the stomata. Water is obtained by the plant through the roots and delivered to the leaves through .
In summary, photosynthesis is a process in which light energy is converted to chemical energy and used to produce organic compounds. In plants, photosynthesis typically occurs within the chloroplasts located in plant . Photosynthesis consists of two stages, the light reactions and the dark reactions. The light reactions convert light into energy (ATP and NADHP) and the dark reactions use the energy and carbon dioxide to produce sugar. For a review of photosynthesis, take the .
I was wondering if all plants use carbon dioxide
I have koi in outside fish ponds. At times during the long summer days there is an occurrence called an algae bloom where the water in the pond becomes filled with very small suspended algae. During the day there is no problem with the respiration of the koi that I have in the pond… but because the algae use up so much available oxygen during the night and do not add any O2 to the water…my koi in the very early morning hours before the sunlight starts photosynthesis of the algae run out of the amount of oxygen they need for respiration and are forced to breathe atmospheric O2 at the surface of the pond! They gasp for O2 out of the water from the atmosphere where there is enough available for them to survive. My point is in water ponds there is a semi closed environment where plants can use up so much oxygen at night that they force the fish to get their oxygen elsewhere. When days become shorter the algae bloom will naturally diminish if I wait it out and do not do massive water changes or resort to killing the floating algae with a chemical plant killer algaecide that will not kill my fish if used in the proper doses. Plants do use O2 at night and do not give off any O2 in darkness!
Plantsuse a process called photosynthesis to make food. During photosynthesis,plants trap light energy with their leaves. Plants use the energyof the sun to change water and carbon dioxide into a sugar called glucose.Glucose is used by plants for energy and to make other substances likecellulose and starch. Cellulose is used in building cell walls. Starchis stored in seeds and other plant parts as a food source. That's why somefoods that we eat, like rice and grains, are packed with starch!

This tutorial introduces photosynthesis
We also have to be careful when studying green plants because in the light the green parts of these plants carry out photosynthesis as well as respiration.
The carbon dioxide molecule is linear and centrosymmetric
Photosynthesis does the opposite of respiration. Carbon dioxide is absorbed and oxygen is produced. In order to study respiration in green plants we must block out the light, because although green plants respire all the time they only photosynthesize in the light.
Biology of Plants: Making Food - MBGnet
Plants make their own food by photosynthesis. Carbon dioxide and water react together in the presence of light and chlorophyll to make glucose and oxygen. The glucose is converted into starch, fats and oils for storage. It is used to make cellulose for cell walls, and proteins for growth and repair. It is also used by the plant to release energy by respiration.
C4 photosynthesis: how some plants avoid photorespiration
Plants must get food into their systems in order to acquire energy and continue living, similar to animals. Plants create energy for animals to use, so they must replenish their nutrients. And plants breathe, in a way. They take in the carbon dioxide that all the animals give off, and they give off oxygen for all the animals to use. Pretty cool design, isn’t it?
Photosynthesis in plants occurs in two stages.
Instead of taking in oxygen and breathing out carbon dioxide like animals do, plants take in carbon dioxide from the atmosphere. Plants absorb water from the ground up through their roots.

Enzymes within the plant then catalyze the combination of hydrogen and carbon dioxide to create a carbon compound that is called an . An intermediate is a compound used to continue a process to create a different compound.
