Worked Solution & Example Answer:The diagram below shows the distribution of auxin in a shoot - OCR Gateway - GCSE Biology - Question 12 - 2022 - Paper 1
Step 1
What will happen to the shoot?
Answer
The shoot will bend to the left.
This is due to the uneven distribution of auxin, which is a plant hormone that promotes growth. In the given scenario, there is likely a higher concentration of auxin on the left side of the shoot.
When auxin is concentrated on one side, it causes the cells on that side to elongate more than the cells on the opposite side. This results in the shoot bending towards the side with less auxin, which in this case, is the right side. Therefore, the correct answer is A.
