Today, there is a bioplastic alternative for almost every conventional plastic material and corresponding application bioplastics - plastics that are biobased, biodegradable, or both - have the same properties as conventional plastics and offer additional advantages, such as a reduced carbon footprint or additional waste management options such as composting. The chemical components of a cell matter is made of combinations of elements —substances such as hydrogen or carbon that cannot be broken down or converted into other substances by chemical means the smallest particle of an element that still retains its distinctive chemical properties is an atom. Essential nutrients are simply those that are vital for the normal growth, maintenance and development of the body there might be a slight confusion about essential nutrients that must be addressed the term 'essential' when applied to amino acids and certain fatty acids, applies to those that need to be taken in the diet as they are not. Materials science or materials engineering is an interdisciplinary field involving the properties of material (matter) and its applications to various areas of science and engineering.
