Excretion is known as the process of removing wastes no longer required by the body or a plant. Most wastes that are removed form a new born baby are Carbon Dioxide. This is very important because if the baby is born premature then it has a chance to develop RDS (Respiratory Distress Syndrome). Plants also have different ways of excreting the wastes.
Plants and basic animal’s waste products are removed by diffusion. Plants, for example, excrete Oxygen using photosynthesis. In Humans waste products are removed by special excretory organs, mainly the kidneys, which excrete urea. Water and wastes are also excreted in the faeces and in humans through the sweat glands in the skin, carbon dioxide and water are removed via the lungs and the liver excretes bile.
Plant cells have large vacuoles that can be used for either storage or the storage of waste substances. Crystal formation in the vacuole can form if there is an accumulation of
Some trees deposit strange chemicals in their branches and trunks, especially in old xylem which is probably no longer used for water transport. These are waste materials. Also gardeners find rotted autumn leaves a good source of minerals.
With out trees in the environment excreting wastes in the form of oxygen we could not survive. As humans are dependent on trees as they are dependent of us. Because the trees have a bi-product of oxygen and mammals have a bi-product carbon dioxide there is a very strong association. This can have bad affects as algae consumes oxygen’s and causes water ways to lack oxygen and therefore many fish tend die.
