   Abby planted sunflower seeds from one packet in two rows. In Row 1 the seeds were 2 feet apart. In Row 2 the seeds were crowded together, 1 inch apart. Both rows got the same sun, the same soil and the same watering. After 10 weeks, the Row 1 plants had thick stems and flower heads about 10 inches wide. The Row 2 plants had thin stems and flower heads about 3 inches wide. Abby's brother says, "Row 2 must be a different kind of sunflower, one with small flowers." Is he right? Explain with evidence.
