Final answer:
pH is important for plant growth and development because it aids in the proper absorption of nutrients.
Step-by-step explanation:
pH (the measure of acidity or alkalinity) is important for plant growth and development because it aids in the proper absorption of nutrients. The pH of the soil affects the availability of essential nutrients to plants. When the pH is too acidic or too basic, certain nutrients become less available, which can hinder plant growth. Maintaining the appropriate pH level ensures that plants receive the necessary nutrients for healthy growth.
