Great question! Plants produce oxygen, because when they photosynthesize, they take carbon dioxide (CO2; a gas-form of carbon bonded to two oxygen molecules) and water (H2O; an oxygen bonded to two hydrogen atoms) and combine them using light energy to produce sugars and oxygen.

Plants produce oxygen as a waste product of making sugar using sunlight, carbon dioxide, and water. If a plant needs energy, but doesn't have sunlight, then it can burn the sugar that it made back when it had sunlight, and doing so requires oxygen.

Oxygenating plants do provide some oxygen in the daylight when they photosynthesize, but at night this process is reversed and they consume some of the oxygen as they respire. However the benefit of oxygenating plants in producing oxygen for fish tends to be over exaggerated. The small amount of oxygen that they produce is insignificant compared to that created through the splashing or movement of water. Oxygenating plants help condition the water, by absorbing nutrients such as ammonia, nitrates and nitrites as well as other minerals and salts.

Answer Wiki. Algae and Phytoplankton's are the aquatic plants who use energy from the sun to convert carbon dioxide and nutrients into complex organic compounds around his process is known as photosynthesis and release oxygen as by-product. Views · View Upvotes.

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.

This principle is illustrated in the life of plants. The light initiates a process of photosynthesis whereby green plants convert energy from the sun to transform carbon dioxide and water into glucose and oxygen. Plants rely on this process for growth and propagation.

Quick Answer. During photosynthesis, plants take in carbon dioxide and water, disassemble the molecules and convert them into sugar and oxygen. The water molecules are split into hydrogen and oxygen, and the hydrogen joins carbon dioxide to create sugars. The excess oxygen is released into the atmosphere during the respiration cycle.

A primary difference between plants and animals is the plants ability to manufacture its own food. In photosynthesis carbon dioxide from the air and water from the soil react with the suns energy to form carbohydrates (sugars and starches). Photosynthesis literally means to put together with light.

In photosynthesis, the suns energy combines hydrogen from water (H20) with carbon dioxide (CO2) turning them into carbohydrates. Oxygen (O2) is given off as a by-product of photosynthesis. The chemical equation for the process of photosynthesis is: 6CO2 + 6H20 + light C6H12O6 + 6O2.

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.
