Leaves originate from ______ and are arranged in an _______ order.

Options

A. Root apical meristem, acrospetal
B. Floral meristem, basipetal
C. Shoot apical meristem, acropetal
D. Internodes, basipetal.

Answer

**Step-by-Step Solution:**

1. **Identify the Origin of Leaves:**
- Leaves originate from the **nodes** of the stem. The nodes are the points on the stem where leaves are attached.

2. **Understand the Arrangement of Leaves:**
- Leaves are arranged in an **acropetal** order. This means that the younger leaves are found at the top (apex) of the stem, while the older leaves are located lower down, closer to the base.

3. **Clarify the Terms:**
- **Acropetal fashion** refers to the arrangement where new structures (in this case, leaves) are produced at the apex and older structures are positioned below them.
- This is in contrast to **basipetal fashion**, where new structures would be at the base and older ones at the top.

4. **Conclusion:**
- Therefore, the complete answer to the question is: Leaves originate from **nodes** and are arranged in an **acropetal** order.

**Final Answer:**
Leaves originate from **nodes** and are arranged in an **acropetal** order.
