Question

What is karyoplasm?
A) Nucleoplasm
B) Hyaloplasm
C) Deutoplasm
D) Both A and B

Answer 1

Hint: Karyoplasm is cell sap that is similar to that of cytoplasm. It is also present in the nucleolus and the chromosomes. It is a living substance that is made up of proteins, organic and inorganic substances.

Complete answer:
The term nucleoplasm was coined by Edouard Van Beneden in the year of 1875 while the term karyoplasm was coined by Walther Flemming in the year of 1878. The nucleoplasm or karyoplasm is thus a type of protoplasm that is enveloped by the nuclear envelope. Nucleotides which are necessary for DNA replication along with essential enzymes that help in the proper functioning of the nucleus are often found dissolved in the nucleoplasm. DNA replication is known to be very important in the division of the cell without which the cell may not survive.

Hyaloplasm on the other hand refers to the clear fluid portion of the cytoplasm that is known to contain minerals, water, sugar, amino acids, etc. the hyaloplasm is also known as the ground substance.
The deutoplasm on the other hand stands for the food that is stored in the cytoplasm of an ovum or cell. The deutoplasm is known to accumulate around the nucleus of the cell and is generally heavier than the surrounding cytoplasm. In some animals, the deutoplasm is completely separate from the cytoplasm.

So the correct option is A) Nucleoplasm.

Note: The nucleoplasm is the type of protoplasm which is enclosed within the nuclear membrane. All the three options mentioned in the question that is nucleoplasm, hyaloplasm and karyoplasm, are very important in the proper functioning of the cell. Thus, having adequate knowledge about them and their function helps us have an idea about how the cells work.
