All cells rely on cell signaling to detect and respond to cues in their environment. This process not only promotes the proper functioning of individual cells, but it also allows communication and ...

The table below list organelles, their function and the types of cell that they can be found in. Can you fill in the blanks to complete the table? Cell structure Description Function Cell type Cell ...

Essentials of Biology is a non-majors general biology course without a laboratory. The topics that will be covered include biological molecules, cell structure and function, cellular metabolism, cell ...

The cell is the structural and functional unit of living organisms. It was discovered by Robert Hooke in 1665. Cell in Latin means “little room”. Many organisms, such as bacteria, protozoa and yeasts ...

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 these ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

A new structure in human cells has been discovered. The structure is a new type of protein complex that the cell uses to attach to its surroundings and proves to play a key part in cell division. A ...

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.
