Osmosis and its importance in living organisms essay

Bet You Didn't Know the Importance of Osmosis in Living Organisms In living organisms, nutrients derived from food reach various organs by way of osmosis, carried by fluids. It's the process of flow of liquid through a semi-permeable membrane. BiologyWise Staff Last Updated: Mar 19, 2018 Solids and liquids share a simple, yet complex relationship. Simple, because often, solids yield to the solvent power of liquids and both get bound to each other in the form of a solution.

The process of osmosis and its importance to living organisms.

Complex, because a lot of times, liquids find it challenging to breach the surface of solids and move ahead. The phenomenon by which a liquid moves towards its destination by breaching a partially permeable or semi-solid surface without the use of any force is known as Osmosis.

Two U-shaped tubes with semipermeable membranes and containing liquid.

  1. In the human body, the kidneys provide the necessary regulatory mechanism for the blood plasma to be an isotonic solution to prevent excesses amounts of water and salts leaving the body and maintain the correct concentration of water by removing salt from the blood. This causes and increase of water concentration in the outer root cells, than in surrounding root cells, water therefore moves in to adjacent root cells by osmosis.
  2. This causes and increase of water concentration in the outer root cells, than in surrounding root cells, water therefore moves in to adjacent root cells by osmosis.
  3. The symplast pathway does not require osmosis as there are no further membranes to pass through until the water reaches the xylem. This increases the osmotic potential; therefore the tissue fluid is reabsorbed back into the venule via osmosis.

In living organisms, osmosis mostly takes place in the form of a nutrient-laden liquid permeating the cell membrane to move towards the inner cellular anatomy where the solute concentration is higher owing to the presence of various organelles that carry out a number of essential functions necessary for the sustenance of life.

By enabling nutrients to reach the cellular interiors and aiding in their absorption, the process of osmosis makes sure that cells get repaired and stay healthy. Significance of Osmosis in Living Organisms Besides carrying nutrient-rich liquid across cell membranes, a very important function of osmosis is to maintain an ideal concentration of solute within the cell.

  1. This causes water to move into the gut via the process of osmosis. If the water potential of the cell is lower than that around the cell water will move across a concentration gradient into the cell.
  2. Therefore osmosis is proven to be a very important element to plant survival water movement, and mass movement in plants.
  3. This causes the pressure inside the cell to be equal to that outside of the cell, this hydrostatic pressure prevents further uptake of water by the plant cell. Like with all cells when the water potential inside the cell is higher than that outside the cell water moves out of the cell, causing the cell to shrink in size.

Osmosis balances the pressure and concentration of solution on both sides of a semi-permeable membrane by making water molecules move from the high-concentration side to the low concentration side by passing through the wall of semi-absorbent material that lies between both sides. The following points enumerate the comprehensive role osmosis plays in the biology of living organisms: If fluid volume within a cell is more than the fluid volume outside it, such pressure could lead the cell to become turgid and explode.

On the contrary, if fluid volume outside the cell is more than the fluid volume within, such pressure could lead the cell to cave in. Both cases would be detrimental to normal and healthy cellular function.

Importance of Osmosis in Living Organisms and Beings

Plants wouldn't exist without osmosis and without plants, no other life could exist as they are a vital link of the entire food chain of the planet. The process of blood purification is carried out by the kidneys which isolates the impurities in the form of urine, which is, then, carried to the bladder from where they are, eventually, sent ahead for evacuation from the body.

The role of osmosis is twofold - it helps maintain a stable internal environment in a living organism by keeping the pressure of the inter and intra-cellular fluids balanced, and it allows the absorption of nutrients and expulsion of waste from various bodily organs on the cellular level.

These are two of the most essential functions that a living organism cannot do without, as a steady internal pressure is essential to counter the atmospheric pressure from the outside, and the transfer of nutrients and cellular waste by using the least number of energy units the process of osmosis does not involve the exertion of any kind of force ensures that any energy produced or processed by the body is directed towards the performance of more complex biological functions.
