The correct Answer is:
To solve the question "If the apical bud has been removed then we observe:", we need to understand the concept of apical dominance and its effects on plant growth. ### Step-by-Step Solution: 1. **Understanding Apical Bud and Apical Dominance**: - The apical bud is located at the tip of the plant shoot and is responsible for the growth of the plant in height. - Apical dominance is a phenomenon where the growth of the central stem (apical bud) is favored over the growth of lateral buds (axillary buds). This is primarily regulated by plant hormones, particularly auxins. 2. **Role of Auxins**: - Auxins are hormones produced in the apical bud that inhibit the growth of lateral buds. This means that as long as the apical bud is intact, the lateral buds remain dormant or suppressed. 3. **Effect of Removing the Apical Bud**: - When the apical bud is removed, the source of auxins is also removed. This leads to a decrease in auxin concentration in the plant. - As a result, the inhibition on the lateral buds is lifted, allowing them to grow. 4. **Observation After Removal**: - With the apical bud removed, the lateral buds start to grow, leading to an increase in lateral branching. This results in a bushier appearance of the plant. 5. **Conclusion**: - Therefore, the correct observation when the apical bud is removed is that there will be **more lateral branches**. ### Final Answer: - The answer is **option A: more lateral branches**.
