LIFE SCIENCE

Detailed explanation-1: -Protoplasm is called the living substance of the cell. (Protoplasm = Cytoplasm + Nucleus)

Detailed explanation-2: -In eukaryotic cells, the cytoplasm includes all of the material inside the cell but outside the nucleus, which contains its own watery substance called nucleoplasm. All of the organelles in eukaryotic cells, such as the endoplasmic reticulum and mitochondria, are located in the cytoplasm.

Detailed explanation-3: -The cytoplasm is the gel-like material within a living cell, excluding the nucleus. The fluid inside the nucleus is called nucleoplasm.

Detailed explanation-4: -Protoplast refers to an entire cell including the cell membrane, cell organelles and the nucleus, excluding the cell wall (in plants and few algae). Cytoplasm refers to the living the material or the protoplast within a cell excluding the nucleus. So the correct answer is ‘Cytoplasm’.

Detailed explanation-5: -Final Answer: The part of the cytoplasm excluding the organelles is called cytosol.
