An angiospermic plant starts producing flower. This is the beginning of

Options

A. Juvenile phase
B. Vegetative phase
C. Reproduction phase
D. Senescent phase

Answer

To answer the question "An angiospermic plant starts producing flowers. This is the beginning of:", we will analyze the life cycle of angiospermic plants and identify the correct phase.

### Step-by-Step Solution:

1. **Understand the Life Cycle of Angiospermic Plants**: Angiospermic plants, also known as flowering plants, undergo several phases in their life cycle. The main phases are:
- Juvenile Phase
- Vegetative Phase
- Reproductive Phase
- Senescent Phase

2. **Identify the Phases**:
- **Juvenile Phase**: This is the early stage of growth where the plant is not yet mature enough to reproduce. This phase is more commonly referred to in animals.
- **Vegetative Phase**: In this phase, the plant focuses on growth and development. It prepares itself for reproduction by developing leaves, stems, and roots.
- **Reproductive Phase**: This phase begins when the plant starts producing flowers. It is during this phase that the plant will undergo reproduction, including the fusion of male and female gametes.
- **Senescent Phase**: This is the aging phase where the plant's cells lose the ability to divide and reproduce.

3. **Determine What Flowering Represents**: The question states that the angiospermic plant starts producing flowers. This is a clear indicator that the plant has matured enough to enter the reproductive phase. Flowering is a key event that signifies the transition from vegetative growth to reproduction.

4. **Conclusion**: Since the production of flowers marks the beginning of the reproductive phase in angiospermic plants, the correct answer to the question is **Reproductive Phase**.

### Final Answer:
The beginning of flower production in an angiospermic plant marks the start of the **Reproductive Phase**.
