What is a characteristic effect of applying amino acid synthesis inhibitors?

• A. Increased photosynthetic rate
• B. Stunting of plant growth
• C. Improved drought resistance
• D. Strengthened stem structure

Answer: (B)

Amino acid synthesis inhibitors are a class of herbicides that disrupt the production of essential amino acids in plants. By inhibiting the pathways responsible for synthesizing these amino acids, the overall metabolic processes of the plant are affected. This leads to stunted growth because amino acids are fundamental for protein synthesis and various cellular functions. Without the necessary amino acids, the plant cannot grow properly or develop normally, resulting in reduced size and vigor. This characteristic effect is particularly relevant in understanding how these herbicides work at a physiological level. The inhibition of amino acid synthesis not only limits the growth of the treated plants but also makes them more susceptible to other stress factors, as they lack the building blocks required for various growth processes and stress responses. Therefore, the stunting of plant growth is a clear and expected outcome of applying amino acid synthesis inhibitors.
