Description:
A. Research Using the Scientific Method
Many researches had made use of the scientific method to device a scientific query that will test the effect of different substances to the cell division by observing changes in
the organisms' physical attributes. In this activity, two substances, A and B, are tested on their effects on the cell division of onion plant. Onion bulbs were submerged and
allowed to grow together with the test substances and the length and number
experiment. Use the table and analyze before you answer the questions that follow.
Here is a video that shows the procedure of growing onions using water. The experiment is based on this. Use only as a reference. https://www.youtube.com/watch?
