Yes. All living things, except maybe the extremophiles that live near volcanic vents in the bottom of the sea, require oxygen to live. Even green plants need oxygen.
Sure, the leaves release oxygen, but the roots must draw in oxygen from air pockets in the soil to live. You can find this out by over-watering a potted plant. Saturating the soil will make the plant wilt and act as though it is drying up even though the soil is soaking wet. The roots have drowned and have died, therefore the rest of the plant runs out of water just as it would if the soil dried completely out.
Every living thing breaks down carbohydrates to release energy. This process requires oxygen. Even plants that live submerged in water need oxygen and get it from leaves and stems that float on the water surface - even kelp in the ocean does this. The things that look like plants in the ocean that don't have above water parts aren't really plants, but are animals that are just rooted in place such as coral, sponges, etc.
Why is it important that plants give off oxygen during photosynthesis
By using photosynthesis. Photosynthesis releases oxygen as a waste product.
The primary way plants use oxygen is through their root cells. In order for a plant to take up water and nutrients from the soil, it must continually grow new root hairs. The cells that make up these hairs are living cells that do not carry out photosynthesis. They are similar to the cells of animals in that they require oxygen and give off carbon dioxide as they burn carbohydrates to obtain the energy they need to function. This is why you can "drown" a house plant by watering it too much. If the soil gets too saturated with water, the plants root cells can't get enough oxygen from the air.
The Carbon - Oxygen Cycle Note: The carbon and oxygen cycles are independent but very closely related. The two cycles have been combined in the assignment below. Some of the information that you find on the carbon cycle will not contain information on the oxygen cycle. Carbon dioxide (CO2) is taken in by plants to be used in the process of photosynthesis. During photosynthesis carbon based compounds are produced from this CO2 and the water (H2O) that is absorbed by the roots of the plant. Plants give off oxygen (O2) as a waste product of photosynthesis. When animals consume plants or other animals they take in the carbon based compounds. Animals inhale the O2 given off by plants and exhale CO2, a waste product of cellular respiration. Plants also take in CO2 and release O2 during the process of cellular respiration. The activities described above are just a part of the interactions which take place in the carbon - oxygen cycle
The conversion of solar energy to chemical energy takes place during photosynthesis. This is done by the chloroplasts in plants as they convert water and carbon dioxide into glucose. Chloroplasts
Why is it important that plants give off oxygen during photosynthesis
In general outline, photosynthesis is the opposite of cellular respiration. CO2+ H2O+sunlight ----> O2 + H2O +carbohydrates.It uses carbon dioxide and the energy from sunlight to make carbohydrates and oxygen (a waste product from plants).
Photosynthesis
Yes, during photosynthesis, plants take in carbon dioxide and water and use sunlight to produce glucose and oxygen as byproducts. Therefore, plants release oxygen into the atmosphere as a result of the photosynthetic process.
They produce glucose and oxygen. Oxygen is given off as a gas.
Yes, plants produce oxygen as a byproduct of photosynthesis. During photosynthesis, plants take in carbon dioxide and water and convert it into glucose and oxygen with the help of sunlight. This oxygen is released into the atmosphere and is essential for human respiration.
Plants give off oxygen during photosynthesis and carbon dioxide during respiration.
Green plants take in carbon dioxide during photosynthesis and give out oxygen. While respiration, all living organisms take in oxygen and carbon dioxide and then give out carbon dioxide.
They convert CO2 to O2 during the day, and the opposite during the night.
Any extra energy (food) which is left over is stored as starch
Plants produce oxygen when exposed to light. They do this by the process of photosynthesis. The oxygen comes from the splitting of water molecules to produce hydrogen ions and the oxygen is expelled as a waste product.
The oxygen released by plants during photosynthesis originates from water molecules. Plants take in water through their roots and split the water molecules into oxygen and hydrogen atoms during the light-dependent reactions of photosynthesis.
