Learn about the basic unit of life, cells, and how they perform all the functions of living things. Compare and contrast prokaryotes and eukaryotes, the two major types of cells, and their characteristics and differences.

“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.” Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.

Nature Cell Biology publishes research of the highest quality across all areas of cell biology, encouraging studies that shed light on the mechanisms underlying fundamental cell...

Cell biology is the study of cells, their physiology, structure, and life cycle. A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular).

Scitable is a website that offers topics and resources on cell biology, the study of cell structure and function. Explore the history, subfields, and applications of cell biology, and how it relates to systems biology.

Cells are the basic units of life that have a cell membrane, cytoplasm, and various molecules and organelles. Learn about the common features, functions, and diversity of cells, and how they are categorized by their genetic material.

In this course, you will engage in the biology of cells of higher organisms. You will study the structure, function, and biosynthesis of cellular membranes and organelles; cell growth and oncogenic transformation; transport, receptors, and cell signaling; the cytoskeleton, the extracellular matrix, and cell movements; …. Show more.

This textbook is focused specifically on the principles and concepts of a foundational Cell Biology course. The book takes a more conceptual approach that highlights how scientists study cells, and how to analyze and interpret experimental results.
