Which is an inorganic substance that helps plants grow?

• A. Soil minerals
• B. Pork
• C. Sugar
• D. Fat

Answer: (A)

Soil minerals are essential inorganic substances that contribute significantly to plant growth. These minerals provide the necessary nutrients that plants need to thrive, including macronutrients like nitrogen, phosphorus, and potassium, as well as micronutrients such as iron, magnesium, and zinc. These elements are crucial for various physiological processes within the plant, including photosynthesis, metabolism, and overall development. In contrast, the other options such as pork, sugar, and fat are organic substances. Pork is a source of protein and is not related to plant nutrition. Sugar, while important as a source of energy in many organisms, is an organic compound produced by plants themselves through photosynthesis. Fats, also organic, serve primarily as energy storage in living organisms and do not provide the minerals essential for plant growth. Thus, soil minerals stand out as the inorganic source vital for promoting healthy plant growth.
