Living organisms are composed of cells, and on the inside of them is cytoplasm, which is about 80 percent water. The cytoplasm is full of a molecular mixture of organelles, proteins, compounds, and ...

All living organisms are made of cells, which are the smallest unit of life. Plants and animals have up to trillions of cells that work together to produce ever more intricate organization and ...

Active transport in the cytoplasm plays critical roles in living cell physiology. However, the mechanical resistance that intracellular compartments experience, which is governed by the cytoplasmic ...

Understanding the human cell is vital to progress in the life sciences and to human health. Cells are the smallest, most basic unit of life responsible for all of life’s processes. A typical human ...

Researchers in UC Santa Barbara neuroscientist Kenneth S. Kosik’s lab have discovered a novel organelle — a previously unknown cell structure whose function it is to help clean up faulty proteins in ...

Researchers have reported that in the liverwort Marchantia polymorpha, the number of mitochondria in the spermatozoid (sperm) is controlled by autophagy during spermiogenesis. A collaborative team of ...

To communicate with its neighbors, animal cells use gap junctions which are symplasmic connections through which molecules can diffuse from one cell to another. In higher plants, the communication ...

A collaborative team of researchers from the National Institute for Basic Biology, the University of Tokyo, and Gunma University in Japan reported that in the liverwort Marchantia polymorpha, the ...
