Cells are the building blocks of organisms. They are the tiny factories which produce energy(ATP/NADP/GTP containing) molecules, proteins, etc..some cells function as carriers of materials form organs to tissues (eg.rbc-carry oxygen from lung to tissues). Some cells function as protectors(skin, wbc , macrophages etc) skin(dermal cells) protect us from external noxious stimuli..... WBC and Macrophages function as warriors against bacteria and viruses. some cells store materials like glycogen , fat etc.....(in liver and periphery). Nerve cells conduct impulses from organs to brain and back. muscle cells contract to produce movements. brain cells(neurons) store and process memory and make needed decisions, Kidney cells filter blood to remove noxious(waste) materials and excess water and salts. Cells of heart helps in pumping blood. Cells of lung control gas exchange. cells of intestine absorb vital materials needed to maintain life from the food we take.

The cell is the functional basic unit of life. It was discovered by Robert Hooke and is the functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life.[1] Some organisms, such as most bacteria, are unicellular (consist of a single cell). Other organisms, such as humans, are multicellular.
Growth and metabolism are the main functions of the cell.
Between successive cell divisions, cells grow through the functioning of cellular metabolism. Cell metabolism is the process by which individual cells process nutrient molecules. Metabolism has two distinct divisions: catabolism, in which the cell breaks down complex molecules to produce energy and reducing power, and anabolism, in which the cell uses energy and reducing power to construct complex molecules and perform other biological functions. Complex sugars consumed by the organism can be broken down into a less chemically complex sugar molecule called glucose. Once inside the cell, glucose is broken down to make adenosine triphosphate (ATP), a form of energy, through two different pathways.

The first pathway, glycolysis, requires no oxygen and is referred to as anaerobic metabolism. Each reaction is designed to produce some hydrogen ions that can then be used to make energy packets (ATP). In prokaryotes, glycolysis is the only method used for converting energy.

The second pathway, called the Krebs cycle, or citric acid cycle, occurs inside the mitochondria and can generate enough ATP to run all the cell functions.
