Final answer:
Inorganic fertilizers provide essential nutrients like nitrogen and potassium to plants, which are true helpers for the development of plant roots, flowers, shoots, and fruits.
Step-by-step explanation:
Inorganic fertilizers do indeed help the development of roots, flowers, shoots, and fruit by providing key nutrients such as nitrogen (N) and potassium (K). These nutrients are essential for various physiological processes in plants, including growth and reproduction. Therefore, the statement that inorganic fertilizers help the development of these plant parts is true.
Inorganic fertilizers supply plants with minerals that are not otherwise readily available in the soil. These minerals can come in the form of simple inorganic compounds, which are absorbed by the plant roots. For instance, nitrogen is critical for plant growth since it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (photosynthesis). Potassium, on the other hand, helps with the regulation of plant processes, including water uptake and enzyme activation.
