The entire content of a living cell is known as ______ which includes the cytoplasm and the nucleus.

protoplasm

The correct answer is Option (2) - protoplasm

The entire content of a living cell, which includes the cytoplasm and the nucleus, is known as: Protoplasm

Protoplasm refers to the collective contents of a living cell, encompassing the cytoplasm and the nucleus. It is the jelly-like substance that fills the cell and contains various organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes, among others. The cytoplasm, which comprises the fluid portion of the protoplasm, surrounds the cell organelles and is where many cellular processes take place. The nucleus, often referred to as the control center of the cell, contains the cell's genetic material (DNA) and regulates gene expression. Together, the cytoplasm and the nucleus make up the protoplasm, the essential living substance of the cell where cellular activities occur.
