Arrange the following phases of plant life cycle in correct sequence of their occurrence
I. Juvenile phase II. Vegetative phase III. Reproductive phase IV. Senescence phase

Options

A. I, II, III, IV
B. III, II, IV,I
C. II,II,I, VI
D. IV, III, II, I

Answer

To arrange the phases of the plant life cycle in the correct sequence of their occurrence, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Phases**: The phases of the plant life cycle given are:
- I. Juvenile Phase
- II. Vegetative Phase
- III. Reproductive Phase
- IV. Senescence Phase

2. **Understand Each Phase**:
- **Juvenile Phase**: This is the very young phase of the plant, where it is in its early developmental stage.
- **Vegetative Phase**: This phase represents the transition from the juvenile stage to adulthood, where the plant grows and develops its structures.
- **Reproductive Phase**: In this phase, the plant becomes capable of reproduction, producing flowers, seeds, or other reproductive structures.
- **Senescence Phase**: This is the final phase of the plant's life cycle, marking the decline in vitality and the eventual end of the plant's life.

3. **Arrange the Phases in Order**:
- The correct order based on the understanding of each phase is:
1. Juvenile Phase (I)
2. Vegetative Phase (II)
3. Reproductive Phase (III)
4. Senescence Phase (IV)

4. **Final Sequence**: Therefore, the correct sequence of the phases of the plant life cycle is:
- I → II → III → IV

### Answer:
The correct sequence is: **I, II, III, IV** (1, 2, 3, 4).
