Question

Which one of the following is not a role played by potassium in plant growth?
A. Translocation of carbohydrates
B. Maintaining anion-cation balance
C. Opening and closing of stomata
D. Synthesis of proteins
E. Maintaining turgidity of cells

Answer 1

Hint: In plant tissue, potassium is linked to the flow of water, minerals, and carbohydrates. It influences protein, starch, and adenosine triphosphate (ATP) production by activating enzymes within the plant.

Complete answer:
A considerable portion of plant potassium is present in soluble form in cell sap. Potassium promotes root growth, strengthens stalks, stimulates enzymes, regulates plant turgidity, transports sugar and starch, aids protein synthesis, and protects against illness. In plant tissue, potassium is linked to the flow of water, minerals, and carbohydrates. It influences protein, starch, and adenosine triphosphate (ATP) production by activating enzymes within the plant. The rate of photosynthesis can be controlled by the creation of ATP.
The transport of water, minerals, and carbohydrates in plant tissue is linked to potassium. It influences protein, starch, and adenosine triphosphate (ATP) production via regulating enzyme activation within the plant. Potassium does not play a role in translocation of carbohydrates in plant growth.

Hence option A. is the correct one.

Note:
Potassium is a nutrient that is required for plant growth. Because plants absorb considerable amounts of potassium during their life cycle, it is regarded as a macronutrient. Minnesota soils can provide some potassium for crop production. Potassium is beneficial to plants that produce fruit and flowers, such as rose bushes and fruit trees.
