The correct answer is C. Protoplasm.
Protoplasm is the jelly-like substance found in all living cells. It is made up of water, proteins, carbohydrates, lipids, and nucleic acids. Protoplasm is responsible for all the activities that take place in a cell, such as metabolism, respiration, and reproduction.
Cytoplasm is the fluid inside a cell that contains all the organelles. It is made up of water, proteins, carbohydrates, lipids, and ions. Cytoplasm helps to transport nutrients and wastes around the cell and provides a medium for chemical reactions to take place.
Nucleoplasm is the fluid inside the nucleus of a cell. It contains the chromosomes, which are made up of DNA. Nucleoplasm helps to protect the DNA and provides a medium for chemical reactions to take place.
Haloplasm is a term that is sometimes used to describe the cytoplasm of halophilic bacteria. Halophilic bacteria are bacteria that can live in very salty environments. Haloplasm contains proteins that help the bacteria to survive in these harsh conditions.
In conclusion, the physical basis of life is protoplasm. Protoplasm is the jelly-like substance found in all living cells. It is made up of water, proteins, carbohydrates, lipids, and nucleic acids. Protoplasm is responsible for all the activities that take place in a cell, such as metabolism, respiration, and reproduction.
