Document Summary
Cells make up all living organisms; therefore the fundamental units of life. Cells: small, membrane-enclosed units filled with a concentrated aqueous solution of chemicals and endowed with the extraordinary ability to create copies of themselves by growing and diving in to two. A bacterial cell is about a micrometers or m. Cells vary no less widely in their shapes and functions. Cells are also enormously diverse in their chemical requirements and activities. All cells have a way to pass on genetic information to the next generation. With the microscope, animals and plants were proven to be assembled by cells and that cells exist as independent organisms. Individual cells are living in the sense that they can grow, reproduce convert energy from one form into another, control their internal workings, and respond to their environment and so on. Cells may look different but all living things are fundamentally similar inside.
