Question

A scientist wants to test the effect of different amounts of sunlight on the growth of tomato plants. She plants three groups of tomato plants and exposes them to different amounts of sunlight: Group A receives 4 hours of sunlight per day, Group B receives 8 hours per day, and Group C receives 12 hours per day. All other conditions, such as water and soil type, are kept the same. After 4 weeks, the scientist observes that Group A plants grew an average of 10 cm, Group B plants grew an average of 20 cm, and Group C plants grew an average of 22 cm.

What conclusion can the scientist draw from this experiment?

Options

More sunlight always results in faster plant growth.

Plants exposed to 12 hours of sunlight grow taller than those exposed to 8 hours.

Plant growth increases with sunlight up to a certain point.
