Foliage leaves (needles) in Pinus are borne by

Options

A. dwarf shoots
B. long shoots
C. both 1 and 2
D. female strobilus

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Pinus:**
- Pinus, commonly known as pine trees, has two types of branches: long shoots and dwarf shoots.

2. **Identifying Long Shoots:**
- Long shoots are characterized by unlimited growth. They have an apical bud at the apex, which allows them to grow indefinitely. These shoots also bear many scaly leaves.

3. **Identifying Dwarf Shoots:**
- Dwarf shoots, on the other hand, have limited growth and do not contain an apical bud. They arise from the axils of the scaly leaves on long shoots.

4. **Foliage Leaves in Pinus:**
- The foliage leaves of Pinus, which are needle-like, are primarily borne by the dwarf shoots. These needles are initially bound together by a basal sheath and eventually fall off as they mature.

5. **Evaluating the Options:**
- The options provided were:
- A) Dwarf shoots
- B) Long shoots
- C) Both 1 and 2
- D) Female strobilus
- Since the needles are borne by dwarf shoots, the correct answer is option A.

6. **Conclusion:**
- Therefore, the correct answer to the question is that foliage leaves (needles) in Pinus are borne by **dwarf shoots**.
