Answer:
There are 13 levels of organization. In sequence, they are represented as atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, population, community, ecosystem, biome, and biosphere.
Atom: It is the most basic and fundamental unit of matter. It consists of a positively charged nucleus that is made up of protons and neutrons, and revolving around them are the negatively charged electrons. An atom that consists of an equal number of protons and electrons is neutral and stable. In case of unequal number of protons and electrons, it is termed as an ion. Ions are either positive or negative.
Molecule: The formation of chemical bonds between two or more atoms leads to the formation of a molecule. It is one of the most fundamental and stable components of matter. Chemical compounds exist as molecules.
Organelle: It is the subunit of a cell, and consists of a group of functioning biomolecules. Organelles take part in the chemical reactions and interactions in the cellular processes of an organism. Organelles in eukaryotic cells are different from those in prokaryotic ones. A few examples include nucleus and chloroplasts (plant cells), and golgi bodies and mitochondria (animal cells).
Cell: It is considered as the basic unit and building block of life. It is bound by a cell membrane, and possesses a nucleus which acts as its brain. Cytoplasm surrounds the nucleus, which contains cell organelles like mitochondria, ribosomes, vacuole, endoplasmic reticulum, chloroplasts, peroxisomes, and ventricles. The average number of cells in a human body is 100 trillion. They are known to bring about conversion of nutrients into energy, reproduction (cell division), and to carry out specialized functions. Basically, they are of 2 types; prokaryotic and eukaryotic. Prokaryotic cells have a smaller size and simpler form, and lack a nucleus. Eukaryotic cells are more specialized in structure than the prokaryotic ones. Moreover, they are larger in size (by almost 15 times).
Tissue: This level is a combination of different types of cells which perform specialized functions. The group of cells that form a tissue need not be identical, but they should have the same origin. Different types are the nervous, muscle, connective, and epithelial tissues. Connective tissues are fibrous in nature, and they are made up of cells that are separated by an extracellular matrix. Muscle tissues are actively contractile, and useful for producing force and motion. Nervous tissues form organs like the brain and the spinal cord. Epithelial tissues cover the surface of body organs.
Organ: It performs certain functions with the help of different tissues. The major organs of animals include lungs, brain, liver, etc., whereas roots, stem, and leaves are the different organs of plants. Organs can be classified on the basis of the functions they perform. For example, in case of animals, the tongue, ears, eyes, skin, and nose are sensory organs. Flowers and seeds are the reproductive parts of plants. These units are formed by tissues that serve a common function. There are two types of tissues that form an organ; the main and sporadic tissues. For example, in the heart, myocardium is the main tissue, while the blood, nerves, and connective tissues are sporadic.
Organ System: Organs working together to perform certain functions form organ systems. Examples are the circulatory system in animals, and the vascular system in plants. The organs in an organ system are interdependent, i.e., they work in harmony to carry out various body functions. For example, the digestive system that carries out the process of digestion consists of salivary glands, stomach, esophagus, gallbladder, liver, intestines, pancreas, rectum, and anus.
Organism: An organism could either be unicellular or multicellular. The ones that are closely related can be grouped together under a single genus. An organism can be defined as the fully functional form of a living being that can thrive in a particular environment.
