Worked Solution & Example Answer:Which one of the following conclusions can be drawn from this data with respect to the growth of P - VCE - SSCE Biology - Question 40 - 2021 - Paper 1
Step 1
D. TIBA in high concentrations inhibits stem elongation but increases the number of lateral shoots when compared to the seedlings in the control group.
Answer
Based on the available data, the most logical conclusion is that TIBA, when used in high concentrations, inhibits the elongation of stems while simultaneously increasing the number of lateral shoots. This indicates a potential regulatory role of TIBA in plant growth, promoting lateral shoot development at the expense of vertical growth. Such findings can often be critical in understanding plant hormone interactions and optimizing conditions for desired growth patterns in seedlings.
