Cell wall shows
Show Hint
A cell wall is a tough and flexible layer surrounding the cell membrane in plants, algae, and most prokaryotes.
- complete permeability
- semipermeability
- differential permeability
impermeability
The Correct Option is A
Solution and Explanation
A cell wall is a tough and flexible layer surrounding the cell membrane in plants, algae, and most prokaryotes. The cell wall shows complete permeability as it helps to transport substances in and out of the cell.
- The cell wall mainly provides mechanical support.
- The transportation of molecules through cell walls is governed by the pH.
So, the correct answer is A) 'Complete permeability'.

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
