Plants help people in several important ways, including filtering carbon dioxide into oxygen. They also act as food for both humans and animals and provide the basis for numerous types of medication.Know More
The numerous forest regions throughout the world provide the primary source of oxygen that all humans and animals need to breathe. The large collections of forest treetops collect the excess carbon dioxide deposits humans create during the respiratory process and use it during photosynthesis, processing breathable oxygen as a result. Plants also filter out other pollutants in the air. By storing and removing carbon and other pollutants, they also help to slow down human-caused climate changes. Excess carbon deposited into the atmosphere has a direct effect, as it can alter temperatures and weather patterns.
As a food source, plants are vital to all levels of the food chain. Humans need certain vitamins and minerals found only in plants. Livestock also eat plants as a primary food source. Without plants, animals such as cows, pigs and chickens would not be able to sustain a healthy diet and would eventually die out.
Many common medications use parts of specific plants as ingredients. Many homeopathic and herbal remedies rely on the healing powers of certain plants.Learn more in Botany
Respiration, in which energy is released from carbohydrates for metabolic needs, takes place in plants through a process which can be expressed in a word equation as: glucose + oxygen = energy + carbon dioxide + water. The chemical equation for this process can be expressed as: C6H12O6 + 6O2 = energy + 6CO2 + 6H2O. Respiration, which is a breaking-down process that releases energy, can be viewed as the opposite of photosynthesis, which is a building-up process that takes in energy in the form of light and uses it to produce carbohydrates.Full Answer >
Plants and plant-derived materials provide humans with everything from oxygen, food and medicinally active chemical compounds to building materials, rope and paper pulp. Plants are also used to beautify both indoor and outdoor spaces.Full Answer >
The National Snow and Ice Data Center explains that different species of plants adapt to cold weather in a variety of ways, such as growing in forms that shed snow readily or by retaining dead leaves to help insulate the plant. Unlike birds and other animals that can migrate to avoid harsh winter weather, plants must find a way to cope with the cold temperatures without leaving.Full Answer >
Plants are green because of a pigment called chlorophyll. Chlorophyll absorbs all colors of visible light except for green, which is reflected. Thus, the reflection of the green part of visible light is what causes plants to look green.Full Answer >
