Photosynthesis, which is the process through which some living organisms, including most plants and some fungi, make their own food, produces oxygen as a waste product. The process of photosynthesis in plants is the reverse of the respiration process in humans. While humans breathe in oxygen and expel carbon dioxide, plants ingest carbon dioxide and dispel oxygen.Continue Reading
While the processes of photosynthesis and respiration in plants and humans are similar, they take place for different reasons. Plants rely on photosynthesis to produce food and energy that they need to survive and carry out basic functions, including reproduction. Photosynthesis is considered to be a chemical reaction, and begins when water and carbon dioxide combine. The interaction of these two substances takes place only when sufficient light is available.
In addition to light, photosynthesis requires pigmentation called chlorophyll to take place. Chlorophyll helps to produce glucose and oxygen. After production, glucose may be converted into one of several substances. It can take the form of a starchy material or can transform into fats and oils. After completing its cycle, photosynthesis produces excess amounts of oxygen and smaller amounts of glucose, which are dispersed into the atmosphere upon exhalation. As with respiration, photosynthesis takes place during the day and night, but is more common during the day.Learn more about Botany
Photosynthesis plays an important role in the environment for several reasons as it helps clean the air because plants use the carbon dioxide in the air for photosynthesis, the plants produce oxygen as a by-product which all humans and animals need to live and it also makes plants grow, providing food for animals that feed on plants. Without plants, the world would quickly become uninhabitable for human and animal life. The oxygen would be used up and there would be no food to feed the animals that humans rely on for food.Full Answer >
Microbe World indicates that fungi absorb food from their immediate surroundings directly through their cell walls unlike animals, which eat food, and plants, which produce their own food through the process of photosynthesis. Kew Gardens adds that fungi function like an inside-out version of an animal's stomach. Instead of eating food and digesting it internally, fungi first dissolve food into simpler nutrients and then absorb the food after they digest it.Full Answer >
Photosynthesis, the process by which plants convert the sun's energy to glucose, takes place during daylight hours when the plant's leaves are exposed to sunlight. This process only occurs in green plants and in some protist species. Carbon dioxide and water must also be present in order for photosynthesis to occur.Full Answer >
Photosynthesis is the process by which plants turn light energy into chemical energy. Plants also need carbon dioxide and water along with the light to complete the process.Full Answer >
