A is the answer to this question. The splitting of the water molecules is the time when oxygen is released into the air. A lot of people may not realize that oxygen is very important right now. A lot of people are always concerned about the things that they have to do that they do not realize that oxygen is something that is keeping them alive. The process of photosynthesis is important not only for the plant that is bound to get food that will sustain the whole plant but also for us who rely on oxygen in order to survive here on earth. In order to make photosynthesis work, plants need carbon dioxide that they usually get because humans release carbon dioxide whenever they breathe out.
The correct answer to this question is A, Splitting of water molecules. Photosynthesis occurs when the plant absorbs water and carbon dioxide. Once the water is absorbed, the water molecules disassemble. They are then converted into oxygen and sugar. From that point, the water molecules split into two elements, which are oxygen and hydrogen. The element hydrogen joins with carbon dioxide to create sugar. Any other oxygen leftover are released in the atmosphere during the respiration process. Another part of photosynthesis is that plants take in carbon dioxide, as well as water. Plant leaves contain chlorophyll, which absorb the sunlight to make sugar.
A is the answer to this question. Remember that when photosynthesis is taking place, the plant will absorb carbon monoxide and water. The process will ensure that the right nutrients will be received by the plant and the excess oxygen will then be released into the air. This will happen during respiration.
There are a lot of people who do not realize just how important photosynthesis is when, in fact, this is the reason why we have enough oxygen in the air in order to supply us all. Take note that photosynthesis will not take place without some of the key ingredients, such as sunlight, water, and air.
The oxygen during photosynthesis comes from split water molecules. During photosynthesis, the plant absorbs water and carbon dioxide. After the absorption, the water molecules are disassembled and converted into sugar and oxygen. The water molecules are also split into oxygen and hydrogen and the latter (hydrogen) is joined to the carbon dioxide to create sugars. Excess oxygen gathered after all these are released into the atmosphere during respiration.
In another regard, plants take in carbon dioxide (CO2) and water (H2O) during photosynthesis. The Chlorophyll in the leaves absorb sunlight and the water and carbon dioxide are used for making sugar. This sugar is stored for energy. Excess sugar is left behind in the root to work as starch and the excess water and carbon dioxide will evaporate.
The oxygen released during photosynthesis comes from thesplitting of waterduringthe light-dependent reaction. 3. Remember, the electrons lost from the reaction center in photosystem II must be replaced.
