The Cytoplasm 

The cytoplasm consists of everything inside the plasma membrane of the cell, excluding the nucleus in an eukaryotic cell. It includes the watery, gel-like material called cytosol, as well as various structures. The water in the cytoplasm makes up about two thirds of the cell’s weight and gives the cell many of its properties.

Functions of the Cytoplasm

The cytoplasm has several important functions, including:

  1. suspending cell organelles.
  2. pushing against the plasma membrane to help the cell keep its shape.
  3. providing a site for many of the biochemical reactions of the cell.
