Where does the oxygen that plants produce come from

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!

All organisms, animals and plants, must obtain energy to maintain basic biological functions for survival and reproduction. Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2). The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development.


What products do plants produced during photosynthesis that is ..

Oxygen is also produced by the plant in this cycle, which is then let off into the air!

However, plants can’t produce glucose, carbohydrates and oxygen without light. To get through the night, most plants reverse the process of photosynthesis and breathe, like you and I, by burning carbohydrates and oxygen while producing carbon dioxide and water. So surround yourself with plants during the day but remove them from your bedroom at night when you sleep. Consider putting plants in the living and working space, especially in the kitchen and near machines where the cooking fumes and emissions can be absorbed readily by the plants. Mother Nature to the rescue: plants are our best air purifiers. They produce oxygen and eliminate volatile organic compounds (VOCs) at the same time. Most effective are indoor palms, English ivy, ficuses, peace lilies, and
Chrysanthemums—but certainly most leafy indoor plants are fine.


Can plants produce oxygen at night (without light)

Six years ago, I read that the snake plant is one of four plants known to emit oxygen 24 hours a day. We have short and long snake plants, so I did not even try to write the names of the tropical-sounding names of the other three plants. Can you find out? I do know to wipe the leaves of waxy plants often to keep the pores from clogging.

The oxygen is actually a byproduct of photosynthesis

These reactions produce ATP (adenosine triphosphate), which provides energy for cellular reactions, and NADP (nicotinamide adenine dinucleotide diphosphate), essential in plant metabolism.

The entire process can be explained by a single chemical formula.


While we take in oxygen and give out carbon dioxide to produce energy, plants take in carbon dioxide and give out oxygen to produce energy.

Photosynthesis has several benefits, not just for the photoautotrophs, but also for humans and animals.

Plants produce oxygen in photosynthesis. Where does …

Well, not really. The amount of oxygen the plants in your bedroom use at night is trivial. Think about the earth as a giant bedroom and you’ll see that animals would be in pretty big trouble if plants used up a significant amount of oxygen every night.

do plants produce oxygen? | Yahoo Answers

At night, when photosynthesis can’t take place, plants continue to consume oxygen but they don’t release any back into the room. Would that mean that plants really do compete with humans for oxygen?
