Question

Several scientists stated that plant growth would be similar regardless of the soil type. Students in Ms. Gray’s class performed an experiment to verify this statement, and their data is shown in the table. Note that the three plant samples belonged to the same species and were the same size at the start of the experiment. All other variables were controlled. Which of these conclusions can be drawn from the results? Question 1 options: Smaller particle size of the soil ensures maximum growth of plants. The type of soil has no role in the soil’s water retaining capacity. Growth of a plant is directly proportional to the particle size of the soil. Particle size of soil and aeration capacity play important roles in plant growth

Answer 1

Particle size of soil and aeration capacity play important roles in plant growth
