It is indivisible, i. It cannot be further divided into smaller parts. Even though its size is minute, it retains all the original properties of the chemical element. Every atom consists of three subatomic particles, Electrons negatively charged , Protons positively charged and neutrons no charge. A cell is a term given to one single unit which is enclosed inside a border. Biologically, it is a unit which forms the structural basis necessary for a being to function.
It is hence often referred to as "the building block of life". Organisms can be unicellular, such as amoeba, or multi cellular, such as humans. Organisms can be unicellular, such as amoeba, or multicellular, such as humans. Cosmo Chessher answered. Quite a bit different, but then similar. Prokaryotes are single-celled or colonial organisms that do not have membrane-bound nuclei or organelles; in contrast, the cells of eukaryotes do have membrane-bound organelles and a membrane-bound nucleus.
In larger organisms, cells combine to make tissues , which are groups of similar cells carrying out similar or related functions. Organs are collections of tissues grouped together performing a common function. Organs are present not only in animals but also in plants. An organ system is a higher level of organization that consists of functionally related organs. Mammals have many organ systems.
For instance, the circulatory system transports blood through the body and to and from the lungs; it includes organs such as the heart and blood vessels. Organisms are individual living entities. For example, each tree in a forest is an organism. Single-celled prokaryotes and single-celled eukaryotes are also considered organisms and are typically referred to as microorganisms. All the individuals of a species living within a specific area are collectively called a population.
For example, a forest may include many pine trees. Earth can not survive without atom and cell. Though both of the units are important for the universe, they are different in nature and have different functions. The difference between Atom and Cell is that an atom is the smallest unit of a chemical element, and a cell is the smallest unit of the biological units.
The universe is made of atoms, whereas we humans are made of cells. This whole universe is made by atoms coming together. Solid, gas, liquid, everything is made by atoms. Atoms can be split off into electrons, protons and neutrons. Atom is an essential and inevitable part of anything which has a physical presence.
A cell is part of biology. We are made of cells. Cells come together and make tissues, and tissues make organs.
It takes trillions of cells to make a human body. Atom is the essence of the matter. A matter is anything that has a physical entity. These are minute units; typically the size is around picometers. When considering the structure of an atom, it contains a nucleus and electrons moving around the nucleus.
Further, protons and neutrons and there are some other subatomic particles as well make up the atomic nucleus. Typically, the number of neutrons, protons and electrons are equal to each other, but in the case of isotopes, the number of neutrons is different from that of protons.
A cell is a biological unit, while an atom is a chemical unit. Besides, the key difference between cell and atom is that a cell is made of molecules whereas atoms make up molecules. Also, when considering the composition of these units, a typical cell contains cytoplasm, cell membrane, nucleus, etc.
Moreover, a further difference between cell and atom is that a cell contains macromolecules such as proteins, carbohydrates, lipids and nucleic acid while molecules are made of atoms.
