At the time of active growth ( formation of buds and flowers ) a part of the stored food also moves upward through

Options

A. xylem
B. phloem
C. parechyma
D. both xylem and phloem

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the movement of stored food during the active growth phase of a plant, specifically when buds and flowers are forming.

2. **Identifying Stored Food**: Stored food in plants primarily consists of organic materials produced through photosynthesis. This food is stored in various parts of the plant, including roots and stems.

3. **Understanding Plant Transport Systems**: Plants have two main types of vascular tissues: xylem and phloem.
- **Xylem**: Responsible for transporting water and minerals from the roots to the rest of the plant.
- **Phloem**: Responsible for transporting organic nutrients (like sugars) produced during photosynthesis from the leaves to other parts of the plant.

4. **Analyzing the Options**:
- **Xylem**: Primarily transports water and minerals; not the main pathway for moving stored food.
- **Phloem**: Transports organic nutrients, including stored food, to growing parts of the plant.
- **Parenchyma**: A type of plant tissue that serves various functions but is not primarily involved in transport.
- **Both Xylem and Phloem**: While both tissues are important, only phloem is responsible for moving stored food.

5. **Conclusion**: During the active growth phase, the stored food moves upward through the **phloem** to supply nutrients to the developing buds and flowers.

**Final Answer**: The correct answer is **phloem**.
