Cell Biology

Cell, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.

The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known living organisms.

Information about cell biology from the American Society For Microbiology.

Cell Membranes Learn that membranes are fluid, with components that move, change, and perform vital physiological roles as they allow cells to communicate with each other and their environment.

Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life. Focusing on the cell permits a detailed understanding of the tissues and organisms that cells compose.

The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. Learn more here.

BioInteractive offers many great resources for teaching cell biology, including short films, animations, Click & Learn interactives, and posters.

You, my friend, are made up of cells. Lots and lots of them. Some of them are eukaryotic (human), but many more of them are prokaryotic, thanks to the friendly bacteria of your gut, skin, and other body systems. Jump in to learn more about prokaryotic and eukaryotic cells and the complex and beautiful structures inside of them.

This tutorial introduces cell structure. Other sections include plants, animal systems, invertebrates, vertebrates, and microorganisms.

All living things, including you, are made up of cells. Find out how cells divide through mitosis and meiosis, how the cell cycle is controlled, and how problems in cell cycle control can lead to cancer.

Cells are the fundamental unit of life, composed of billions of molecules: DNA, RNA, proteins, glycans, lipids, and small molecules that have defined molecular properties and biological activities. Each cell is able to respond to its environment and to communicate with other cells to create tissues, organs, and whole organisms.

Welcome to the Molecular and cell biology portal. Molecular biology is the study of biology at the molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Cell biology studies the properties of cells including their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division and death.

In biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.

Cell biology and otherwise known as molecular or cell biology, is a branch of biology that studies the different structures and functions of the cell and focuses mainly on the idea of the cell as the basic unit of life. Cell biology explains the structure, organization of the organelles they contain, their physiological properties, metabolic processes, signaling pathways, life cycle, and interactions with their environment.
