Movement of Substances Across a Plasma Membrane and Its Application in Daily Life

Phenomenon of Plant Wilting

Excessive use of fertilisers may cause wilting in plants
Dissolved fertilisers will cause soil water to be hypertonic to the sap cell of roots
Consequently, water will diffuse by osmosis from the roots’ cell sap to the soil, and cells will become plasmolysed
Cells in plants will recover once they are watered
However, if the period of plasmolysis is prolonged, wilted plants will eventually die

The image is an infographic titled Application of Movement of Substances Across Plasma Membrane in Daily Life. It is divided into five sections, each describing a different application: 1. **Rehydration Drinks**: Oral rehydration salts help to recover the loss of water and electrolytes in individuals with diarrhea. 2. **Isotonic Drinks**: Help athletes to recover the loss of water and electrolytes such as potassium and sodium through perspiration. 3. **Saline Solution**: Normally used in medicine, are isotonic solutions to the blood plasma. 4. **Reverse Osmosis**: A technology commonly used to extract fresh water from seawater using the desalination process. 5. **Liposome**: Used to protect drugs from being destroyed by gastric juices

Application of Movement of Substance Across a Plasma Membrane in Daily Life

Rehydration Drinks

An oral rehydration salts help to recover loss of water and electrolytes in individuals with diarrhoea

Isotonic Drinks

Help athletes to recover loss of water and electrolytes such as potassium and sodium through perspiration

Saline Solution

Used in medicine
An isotonic solution to the blood plasma
It contains 0.85–0.90 g sodium chloride per 100 ml

Liposomes

Vesicles that contain aqueous solution surrounded by a phospholipid bilayer membrane
Liposomes are used to protect drugs or active substances taken orally from being destroyed by gastric juices
This way, drugs can reach the target cells

Reverse Osmosis

The technology commonly used to extract fresh water from seawater using the desalination process
In reverse osmosis equipment, pressure is applied to push the seawater through a semi-permeable membrane
The membrane allows water molecules to pass through it but not foreign particles, salt, and microorganisms
As a result, only pure fresh water is released
