Biologist investigated the effect of the presence of aluminum ions on the root tip of a variety of wheat. They removed 2-mm sections of the tips of root. Half of the root tips were placed in a nutrient solution with aluminum ions, while the other half were placed in an identical nutrient solution without aluminum ions. The length of the root tips, in millimeters, was measured every hour for seven hours. The results are shown in the data table.

Transcribed Image Text:Biologist investigated the effect of the
presence of aluminum ions on the root
tip of a variety of wheat. They removed
2-mm sections of the tips of root. Half
of the root tips were placed in a nutrient
solution with aluminum ions, while the
other half were placed in an identical
nutrient solution without aluminum ions.
The length of the root tips, in
millimeters, was measured every hour
for seven hours. The results are shown
in the data table.
