A tree breathes through its leaves using chlorophyll, the substance that makes leaves green. Chlorophyll absorbs the carbon dioxide in the air and uses it alongside water to break down minerals absorbed through the tree's roots. The leaves then release water vapor and oxygen.Continue Reading
The process a tree uses to breathe is called photosynthesis. Photosynthesis is the process that converts energy from light sources into organic chemical energies such as sugar. The leaves absorb the light energy and use it to convert carbon dioxide and water minerals into oxygen and carbohydrates. The oxygen releases into the atmosphere, where it benefits all life on the planet.
Respiration, the opposite of photosynthesis, is another part of the breathing process. It occurs constantly in the tree's cells. Respiration uses up stored oxygen and releases carbon dioxide, energy and water into the atmosphere. While trees do not technically breathe, respiration is comparable to inhaling air into the lungs, and photosynthesis is comparable to exhaling. Even though respiration does not directly benefit the environment, trees still absorb far more harmful carbon dioxide than they release, thanks to the process of photosynthesis. A medium-sized tree releases the same amount of air required for a human being to breathe.Learn more about Botany
Plants need minerals to produce chlorophyll and go through photosynthesis, fight off diseases, produce fruit and leaves, and grow strong stems and branches. Certain minerals also support a plant's growth, seed production, root system and ability to become weather resistant.Full Answer >
When the abscission layer of a plant grows, it cuts off the circulation of nutrients, sugar and water to the leaves, which causes the chlorophyll that gives the plant its green color to disintegrate and makes carotene shine through. The result is the yellow-colored leaves that are found on maple and other trees, such as birch and aspen, in the fall.Full Answer >
Plant leaves contain chloroplasts, which have chlorophyll that absorbs light energy from the sun. Chlorophyll is the green pigment that is important for the process of photosynthesis in plants.Full Answer >
Plant leaves turn yellow for a variety of reasons, including a lack of chlorophyll caused by too much or too little water, insufficient sunlight, temperature changes and disease. Plants contain various pigments such as chlorophyll, which produces a green color, and carotene, which produces a yellow color.Full Answer >
