Plants also have a vital role in the fields of health and medicine. Foxglove, for example, contains chemicals that are used to treat heart failure.
Aloe alleviates symptoms of burns, and other medications combat headaches, certain types of cancer and other ailments.
Plants and microorganisms also play a role in soil remediation, which involves using plants to capture and eliminate harmful toxins in the soil.
Photosynthesis also enables the growth of critical food supplies and cash crops in countries around the world.
One amazing feature of leaves is that they have tiny holes in them to let the gases carbon dioxide and oxygen enter and exit.
One of the holes is called a 'stoma', although just to be confusing, when there are more than one they are called 'stomata'. It is controlled by two guard cells which change shape to either open or close the hole.Since humans and other animals cannot make their own food, they rely on photosynthesis to sustain plants, which in turn provide sustenance for other organisms in the food chain.Photosynthesis also produces oxygen as a byproduct, which is essential for human life and the life of many other organisms.The amounts of water, carbon dioxide, sunlight and temperature.The amount of water is effected by how much is taken up through the roots and how much is lost from the leaves.This creates carbohydrates, or glucose, which is sugar that the plants can store and use later for energy.The other end product of this phase is oxygen, which plants release back into the atmosphere.The last stage in the photosynthesis process involves taking in sunlight.As plants absorb sunlight, a chemical reaction takes place where molecules of carbon dioxide and water are broken down.The formula for photosynthesis is 6CO2 6H2O light energy = C6H12O6 6O2.In words, the equation translates to the combining of water, carbon dioxide and light energy to produce glucose and oxygen.
