Protoplasm is best described as what?

Protoplasm is best described as a colorless, jelly-like substance because it refers to the living contents within a cell, including the cytoplasm and the nucleus. This jelly-like consistency is essential for various cellular functions, as it facilitates the movement of nutrients, organelles, and waste. Protoplasm is primarily composed of water along with various organic and inorganic substances, making its jelly-like nature a critical aspect of life within cells. The other descriptions do not accurately capture the physical state or characteristics of protoplasm, which is cellular and inherently alive, unlike solid masses, gases, or crystalline structures.
