Expert Solution
Step 1: Osmosis - Importance

Osmosis is a vital biological process with multiple functions:

  • For example, it influences nutrient movement and metabolic waste product elimination within living organisms. This means it is critical in the transportation of essential substances as well as the removal of harmful byproducts.
  • It is responsible (in plants) for absorbing water from the soil and distributing it to different parts of the plant via the xylem. This process ensures that plants get enough water to grow and survive.
  • Furthermore, osmosis protects the internal environment of living organisms. It contributes to the maintenance of a balanced and functional internal milieu by regulating water and intercellular fluid levels.
  • One of its essential functions in plant biology is cell turgidity maintenance. This keeps plant cells firm and rigid, supporting the plant's overall structure.
  • Furthermore, osmosis helps plants conserve water by allowing them to retain water despite continuous losses due to transpiration.
  • It also regulates the flow of water within the plant by controlling the diffusion of water between plant cells.
  • Osmosis is also involved in the induction of cell turgor, which regulates plant movement and its various parts.
  • Aside from that, it controls the opening of fruits and sporangia, thereby contributing to plant reproduction.
  • Finally, higher osmotic pressure protects plants from the damaging effects of drought, allowing them to thrive in a variety of environmental conditions.
