Plasmolysis can be defined as the shrinkage of the cytoplasm of a plant cell, away from its cell wall and toward the centre. It occurs because of the movement of water from the intracellular space to the outer-cellular space. This happens when the plant cell is placed in a hypertonic solution (i.e., a solution having more solute concentration than the cell cytoplasm). This causes the water to move out of the cell and toward the solution. The cytoplasm of the cell shrinks and the cell is said to be plasmolysed. This process can be observed in an onion peel kept in a highly concentrated salt solution.

Young’s Modulus

  • Young’s modulus is derived from the name of the scientist who defined it.
  • It is the ratio of longitudinal stress to longitudinal strain.
  • It is denoted by Y.
  • Mathematically:
  • Y= longitudinal stress/ longitudinal strain = σ/ ε
  • = (F/A)/ (ΔL/L)
  • Y=FL/ΔL
  • If Young’s modulus is more, to produce a small change in length more force required.
  • S.I. Unit is N m–2 or Pascal (Pa).
  • Metals have comparatively greater Young’s Modulus. To change the length of metals, greater force is required.
