Ethanol Group 1

The document presents data from an experiment testing the effects of different concentrations of ethanol, methyl linoleate, 2-butanol, and methanol on seed germination and root growth. For each substance, seeds were exposed to concentrations from 0% to 10% and divided into groups. The number and percentage of seeds that germinated and the average root length were recorded. As concentration increased, the percentage of seeds germinating and average root length generally decreased, with higher concentrations inhibiting germination and growth more.
