Question

_______ is called the living substance of the cells.

Answer 1

Protoplasm:

1. Protoplasm refers to the entire contents of a living cell.
2. It consists of the cytoplasm and the nucleus.

Components of protoplasm:

Cytoplasm:

1. The first component of protoplasm is cytoplasm. It is the gel-like substance found between the cell or plasma membrane and the nucleus.
2. Cell organelles are found suspended in the cytoplasm of eukaryotes (cells with nuclei).
3. Endoplasmic reticulum, ribosomes, Golgi apparatus, lysosomes, mitochondria, and so on are examples. - Cytoplasm is crucial in maintaining the shape of a cell.
4. The cytoplasm is where the majority of the cell's important chemical reactions take place.

Nucleus:

1. The second component of protoplasm is the nucleus.
2. The nucleus is a large spherical structure located in the cell's center.
3. It serves as the cell's control center.
4. A nuclear envelope formed by two nuclear membranes separates the nucleus from the cytoplasm.
5. The nuclear envelope is porous, with numerous nuclear pores. It contains the liquid ground substance known as nucleoplasm.
6. The nucleoplasm contains nucleolus and chromatin materials.
7. The nucleus is important in the transmission of hereditary characteristics from parents to offspring.
8. When a cell's nucleus is removed, the protoplasm dries up and eventually dies.

Final answer: Protoplasm is called the living substance of the cells.
