Protoplasm: meaning, definitions and examples
๐ฌ
protoplasm
[ หprลtษหplazษm ]
cell biology
Protoplasm is the living substance of a cell, consisting of the cytoplasm, nucleoplasm, and other organelles. It is responsible for carrying out the essential functions of life. All cellular activities, such as metabolism, growth, and reproduction, occur within the protoplasm. The protoplasm is often seen as the physical foundation of cell life, containing a complex mix of molecules like proteins, lipids, carbohydrates, and nucleic acids.
Synonyms
cell matter, cytoplasm, substance
Examples of usage
- The protoplasm of the cell is where metabolic processes take place.
- Under a microscope, the protoplasm can appear as a jelly-like substance.
- Cell damage often affects the integrity of the protoplasm.

Etymology
The term 'protoplasm' was coined in the mid-19th century, deriving from the Greek roots 'proto-', meaning 'first', and 'plasma', meaning 'something formed or molded'. This term was initially used by scientists to describe the substance within a living cell that was distinct from the surrounding non-living matter. Over time, the concept of protoplasm evolved, with advancements in microscopy and cell biology leading to a better understanding of its composition and function. Originally thought of as a homogenous gel, protoplasm is now recognized as a highly organized structure containing various organelles and a fluid medium. The study of protoplasm has contributed significantly to the fields of molecular biology and cell physiology.
