Question

Which of these are parts of the protoplasm
A. Cell membrane and Cytoplasm
B. Chloroplast and Cell wall
C. Cytoplasm and Nucleoplasm
D. Vacuole and cytoplasm

Answer 1

The living material of any cell is known as protoplasm. Without the protoplasm the cell is dead. The protoplasm part is responsible for transporting material within the cell and outside the cell.

Complete answer:
The structural and functional unit of life is the cell. The main component of the cell is the cell membrane, cytoplasm, and nucleus. Plant cells and some bacterial and fungal cells also have cell walls. The cell wall is a non-living extracellular secretion or matrix of the cell which is closely appressed to it. Cell walls give rigidity to the cell and help to maintain its shape. The cytoplasm is the semi-fluid occupying the maximum volume of the cell. Cytoplasm and nucleoplasm are part of the protoplasm. They both play an important role in the transfer of material in the cell. The cytoplasm contains many organelles. The nucleus contains nucleoplasm Nucleoplasm is a transparent, semi-fluid, and colloidal substance that fills the nucleus. It contains nucleolus and highly extended and elaborate nucleoprotein fibres called chromatin. Cytoplasm and nucleoplasm are the living parts of cells called protoplasm.
Chloroplasts are the organelle that contains chlorophyll pigment and it is present in the cytoplasm of plants. Vacuoles are membrane-bound spaces in the cytoplasm. The single membrane boundary of the vacuole is called tonoplast. In a plant cell, there is a single large central vacuole that can occupy ninety percent of the volume of the cell.
So, the correct answer is (C).
Additional information:
Plasmodesmata form the living component in the dead wall. A number of plasmodesmata or cytoplasmic strands are present in the pit through which the cytoplasm of one cell is in contact with another. These are lined by a plasma membrane and contain fine tubules called desmotubule. The endoplasmic reticulum plays a role in the origin of plasmodesmata. These form the symplastic system between two cells.

Note: When the cell wall of a plant cell, a fungal cell, or bacterial cell is removed then the leftover part of the cell is called protoplast. In other words nucleoplasm or cytoplasm without the cell wall is known as protoplast.
