Benefits of Photosynthesis
By: Elizabeth Bunger
A world without plants!
Can you imagine a world without the sun, plants, or even life? Without plants, humans and all animal species would eventually die out. The sun, water, and even the carbon dioxide that we exhale is used in the process of photosynthesis. This process results in two products: glucose, which is used for energy for plants and the oxygen that we inhale.
could we survive without the sun?
The sun is the source of all energy, therefore it gives energy to plants in order for them to produce a chemical energy called glucose and also oxygen. The sun is also one of the major elements of photosynthesis. Without the sun, plants would not be able to produce enough oxygen in order for humans and animals to survive.
All about plants
Plants are producers meaning that they can make their own food. They are found at the beginning of a food chain because they get their energy from the sun, unlike consumers. Consumers can get their food by eating plants (herbavore), eating another animal (carnivore), or by eating both (omnivore).
Plants have organelles called chloroplasts (only found in plant cells). This is WHERE photosynthesis occurs. Plants also have a chemical in chloroplasts called chlorophyll; this is what gives plants their green color.
Stoma are spaces or openings on the undersides of leaves that allow gas exchange. This means that carbon dioxide can enter the leaf and oxygen can be given off as waste.
Plants use sunlight (radiant energy) to make their own food (chemical energy) called glucose.
Why is photosynthesis is important to us?
Ninety percent of ALL the oxygen on Earth is produced through photosynthesis. If there was no photosynthesis, there wouldn't be any plants, therefore, the human/animal species would eventually die out due to the lack of oxygen. Plants are the main supply of oxygen and without them, life couldn't survive. I encourage everyone to plant trees and greenery to promote more oxygen production. This will not only affect us, but it will support ALL life on the planet.
