An organism is made up of different levels of organization, starting from the simplest unit of matter, the atom. Atoms are the building blocks of molecules, which are the basis for the formation of cells.
Atoms combine to form molecules through chemical bonding. For example, atoms of carbon, hydrogen, and oxygen can bond together to form a molecule of glucose, an important energy source for organisms.
Molecules then come together and interact to form cells, which are the basic structural and functional units of life. Cells are composed of various molecules, including proteins, lipids, carbohydrates, and nucleic acids. These molecules work together to carry out the essential processes necessary for the cell's survival and function.
Multiple cells can then join together to form tissues, such as muscle, nerve, or connective tissues. Different types of tissues work collectively to carry out specific functions in an organism.
Tissues combine further to form organs, which are specialized structures with specific functions within the body. For example, the heart is an organ responsible for pumping blood, and the lungs are organs involved in respiration.
Several organs work together as organ systems to perform specific physiological functions necessary for an organism's survival. Examples of organ systems include the circulatory system, respiratory system, digestive system, and nervous system.
Lastly, all the organ systems interact and form an organism, a complete living being capable of carrying out all the necessary life processes to survive, grow, and reproduce. This organization from atoms to organisms represents the hierarchical nature of life's structure and complexity.
