What is protoplasm in biology?

Protoplasm is the colourless liquid within a cell that comprises the cytoplasm, nucleus and organelles.

A cell is made up of a cell wall that contains protoplasm.

The protoplasm is generally divided into two parts: cytoplasm (that part of the protoplasm that lies outside and around the nucleus) and nucleoplasm (that part of the protoplasm that lies within the nucleus).

The cytoplasm contains various organelles, while the nucleoplasm contains the nuclear material (chromosomes) and nucleoli.
