4 hours ago · The cell theory contends the properties and behaviours of cells, are the fundamental unit of living beings. The cell theory has three critical base propositions, which comprise: living things are made up of one or more cells; the cell is the most basic unit of structure and function for any living organism;
2 days ago · Cell - Molecules, Structure, Biology: Cells are largely composed of compounds that contain carbon. The study of how carbon atoms interact with other atoms in molecular compounds forms the basis of the field of organic chemistry and plays a large role in understanding the basic functions of cells. Because carbon atoms can form stable bonds with four other atoms, they are uniquely suited for the construction of complex molecules. These complex molecules are typically made up of chains and ...
1 day ago · Illustration of Virchow's cell theory. Virchow is credited with several key discoveries. His most widely known scientific contribution is his cell theory, which built on the work of Theodor Schwann. He was one of the first to accept the work of Robert Remak, who showed that the origin of cells was the division of pre-existing cells. [29]

The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).

Stem cells are an ongoing source of the differentiated cells that make up the tissues and organs of animals and plants. There is great interest in stem cells ...
2 days ago · A segment of DNA that codes for the cell’s synthesis of a specific protein is called a gene. DNA replicates by separating into two single strands, each of which serves as a template for a new strand. The new strands are copied by the same principle of hydrogen-bond pairing between bases that exists in the double helix.
