Final Answer:
The semi-fluid substance of a cell that contains all contents outside of the nucleus is called the cytoplasm.
Step-by-step explanation:
The cytoplasm is a gel-like substance within a cell that surrounds the cell's organelles, excluding the nucleus. It consists of water, salts, and various organic molecules. Cytoplasm plays a crucial role in cellular processes, providing a medium for chemical reactions, transport of materials, and structural support for organelles.
While the nucleus houses the genetic material (DNA), the cytoplasm hosts cellular activities. It acts as a site for many biochemical reactions essential for the cell's survival and function. The term "cytoplasm" encompasses both the cytosol (the liquid component) and the organelles suspended within it, collectively contributing to the dynamic processes occurring in a cell.
