Question

Most of the water in turgid plant cells occurs mostly
A. In the nucleus
B. In the vacuoles
C. In the cell wall
D. In the cytoplasm

Answer 1

Hint: Turgidity is the state of being swollen, especially due to high fluid content, the condition of being bloated, distended, or swollen. A turgid cell is a cell that has turgor pressure. The plant that looks healthy i.e. not wilted has cells that are turgid.

Complete answer:
By the presence of the cell wall and the osmoregulatory function of the vacuole, turgidity in plants is made possible. The cell wall protects the cell from cell lysis due to high water influx while the vacuole regulates solute concentration to incite the osmotic movement of water into and out of the cell.
The plant cell stores solutes (e.g. ions and sugars) (particularly, inside its vacuole). Since the inside of the cell has a higher solute concentration than the outside, the water tends to move in.
Vacuoles are non-cytoplasmic sacs that are separated from the cytoplasm by a membrane. Sap vacuoles have dissolved inorganic and organic substances in enclosed sap or water. Tonoplast surrounds the sap vacuole.
So, the correct answer is “Option B”.

Additional Information:
The cytoplasm is the gelatinous liquid that fills the inside of a cell which is composed of water, salts, and various organic molecules.
The nucleus contains genetic material (DNA) of eukaryotic organisms and is a membrane-bound organelle. It facilitates transcription and replication processes.
A cell wall is a structural layer just outside the cell membrane surrounding some types of cells. It can be tough, flexible, and sometimes rigid. It acts as a filtering mechanism and provides the cell with both structural support and protection.

Note:
When water moves into a plant cell, the vacuole gets larger, and pushes the cell membrane against the cell wall, the force of this increases the turgor pressure within the cell and makes it firm or turgid. The pressure created by the cell wall stops too much water from entering and hence prevents cell lysis.
