Antitranspirants in Plants
Answer: D. Phenylmercuric acetate
Explanation:
Antitranspirants are substances that help reduce water loss from the leaves of plants through transpiration. They are commonly used in agriculture to minimize water stress in plants and increase their tolerance to drought conditions. Among the given options, phenylmercuric acetate (PMA) serves as an antitranspirant in plants. Here's why:
1. Phenylmercuric acetate (PMA):
- PMA is a chemical compound that acts as an antitranspirant in plants.
- It reduces water loss by closing the stomata, which are small openings on the surface of leaves through which water vapor escapes during transpiration.
- By closing the stomata, PMA helps plants conserve water and maintain hydration.
2. Cobalt chloride:
- Cobalt chloride is not commonly used as an antitranspirant in plants. It is more commonly used as a moisture indicator or in industrial applications.
3. Mercury:
- Mercury is toxic to plants and is not used as an antitranspirant.
4. Potassium:
- Potassium is an essential nutrient for plants, but it does not serve as an antitranspirant.
In conclusion, phenylmercuric acetate (PMA) is the chemical that serves as an antitranspirant in plants among the given options.
