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.
