Alana conducted an experiment to study plant growth. Alana planted three sets of bean seeds: Set A in nutrient-rich soil, Set B in sandy soil with little water, and Set C in nutrient-rich soil but with no light. After three weeks, Alana observed that Set A had the tallest plants, Set B had small and weak plants, and Set C showed no growth.

• GOT IT!

• I don't get it.

Why did the seeds in Set C fail to grow?

RE-READ PASSAGE IF NEEDED: Alana conducted an experiment to study plant growth. Alana planted three sets of bean seeds: Set A in nutrient-rich soil, Set B in sandy soil with little water, and Set C in nutrient-rich soil but with no light. After three weeks, Alana observed that Set A had the tallest plants, Set B had small and weak plants, and Set C showed no growth.

• The soil lacked nutrients.

• The plants did not receive light for photosynthesis.

• The soil was too dry.

• The seeds were not watered daily.

Answer explanation

The seeds in Set C failed to grow because they did not receive light, which is essential for photosynthesis. Without light, the plants cannot produce the energy needed for growth.
