National 5 Cell structure The functions of cell organelles Cells are microscopic building blocks of unicellular and multicellular living organisms.

The orderly arrangement of cells in tissues depends on complex signaling between cells. Learn how cellular junctions play important roles in cell adhesion and communication.

Students will learn about the chemical and molecular basis of life, cell structure and function, gene structure, expression and heredity, reproduction, development, and evolution. As they learn ...

The cell is the structural and functional unit of living organisms. It was discovered by Robert Hooke in 1665.

Eukaryotic cells form the foundation of complex life, their defining feature being the presence of membrane-bound organelles. This article details the structure of eukaryotic cells and provides ...

The cell nucleus is the site of many important biological functions of the eukaryotic cell. These processes include transcription, replication, splicing and ribosome biogenesis. The effect of ...

Our cells produce a variety of proteins, each with a specific role that, in many cases, means that they need to be in a ...

Prokaryotes are unicellular organisms that lack membrane-bound structures. This article details the structure of prokaryotic cells and provides examples of prokaryotic organisms.

Single-cell technology has revolutionized the field of biological research by enabling the analysis of individual cells, providing unprecedented insights into cellular heterogeneity and function. More ...

It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones.
