What is cytoplasm?

Cytoplasm refers to the material within a living cell, excluding the nucleus. This semi-fluid substance fills the cell and houses various organelles, which perform different functions necessary for the cell's life and operation. The cytoplasm plays a crucial role in several cellular processes, including transportation of nutrients, cell structure maintenance, and the facilitation of metabolic reactions.

The distinction of cytoplasm as the internal environment of the cell is important; it is the site where many activities of the cell occur, such as protein synthesis and energy production. Understanding the role of cytoplasm is fundamental in cell biology, as it forms the basis for how cells function and interact with their surroundings.
