Worked Solution & Example Answer:A student investigated the growth of lateral shoots in bean plants - VCE - SSCE Biology - Question 9 - 2006 - Paper 1
Step 1
C. apical buds produce a substance that inhibits lateral shoot growth.
Answer
Based on the results shown in the graph, it's clear that group X, which had their apical buds removed, exhibits a significant increase in the average length of lateral shoots compared to group Y. This suggests that the presence of apical buds inhibits the growth of lateral shoots. Therefore, we can reasonably conclude that apical buds release a substance that inhibits the growth of lateral shoots.
