The endoplasmic reticulum (ER) forms tight membrane contact sites (MCSs) with several organelles in animal cells and yeast. The function of MCSs between the ER and mitochondria and endosomes are ...

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.

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

Animals display an extraordinary array of structural adaptations that are intimately linked to their functional capacities. From the microscopic organisation of tissues and cells to the macroscopic ...

Cells are the building blocks of life, and they come in various shapes and sizes. All living organisms are made up of cells and these cells have various similarities and differences. They are ...

Animals depend upon plants as an energy source. Chemicals in food are broken down in respiration to create energy stores that can be used by the cell. Animal cells have a basic structure. Below the ...

There are many different types of cells in animals. Each type is specialised for a particular role. These ensure that the organism functions as a whole. The head of the sperm contains the genetic ...

The prefrontal cortex region of the human brain is responsible for a range of complex functions from decision-making to certain types of memory. When something goes wrong in this part of the brain, it ...

Researchers have developed artificial cell-like structures using inorganic matter that autonomously ingest, process, and push out material - recreating an essential function of living cells. Their ...

White blood cells help your body fight inflammation and infections. A high or low white blood cell count may be associated with a number of short-term or long-term health conditions. White blood cells ...
