🔬
Add to dictionary

cytoplasm

[ˈsaɪtəʊˌplæzm ]

Definition

Context #1 | Noun

cell biology

Cytoplasm is the gel-like substance that fills the interior of a cell, excluding the nucleus. It is composed mainly of water, salts, and organic molecules, providing a medium for the cellular processes. Within the cytoplasm, various organelles are suspended, each performing vital functions necessary for the cell's survival and operation. The cytoplasm plays a crucial role in cell metabolism and facilitates the movement of materials around the cell.

Synonyms

cell sap, cytosol, protoplasm.

Examples of usage

  • The cytoplasm is where most cellular processes occur.
  • Organelles are found suspended in the cytoplasm.
  • The cytoplasm contributes to the cell's overall shape.

Interesting Facts

Cell Biology

Origin of 'cytoplasm'

Main points about word origin

  • The word comes from Greek, where 'cyto' means 'cell' and 'plasma' means 'something formed or molded'.
  • It was first used in scientific literature in the 19th century as scientists were learning more about cell structures.
  • The term describes both the liquid and the organelles within the cell, illustrating its importance in biology.

The term 'cytoplasm' comes from the Greek word 'kytos' meaning 'cell' and 'plasma' meaning 'something formed or molded'. The concept of cytoplasm was first introduced by scientists in the mid-19th century, when advancements in microscopy allowed researchers to observe the internal structures of cells. Initially, it was considered just a viscous fluid, but with further studies, it was revealed to be a complex environment for biochemical reactions. Over the years, the understanding of cytoplasm has evolved, highlighting its role in cellular processes such as intracellular transport, signaling, and cellular division. The study of cytoplasm continues to be a vital aspect of cell biology and biochemistry.
