The end of juvenile/vegetative phase marks the beginning of the

Options

A. Reproductive phase
B. Senescent phase
C. Flowering period
D. Maturation phase

Answer

To solve the question "The end of juvenile/vegetative phase marks the beginning of the," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Phases of Life Cycle**:
- The life cycle of organisms consists of several phases: juvenile (or vegetative), reproductive, senescent, and sometimes flowering (in plants).

2. **Define the Juvenile Phase**:
- The juvenile or vegetative phase is characterized by growth and development. It is the period after birth and before the organism reaches reproductive maturity.

3. **Identify What Follows the Juvenile Phase**:
- After the juvenile phase, organisms transition into the reproductive phase. This is when they attain sexual maturity and are capable of reproduction.

4. **Consider Other Phases**:
- The senescent phase follows the reproductive phase and is characterized by aging and a decline in reproductive capacity. The flowering period is specific to plants and occurs during the reproductive phase.

5. **Conclusion**:
- Since the question asks what begins at the end of the juvenile phase, the correct answer is the reproductive phase.

### Final Answer:
The end of the juvenile/vegetative phase marks the beginning of the **reproductive phase**.
