Peat Moss is

Options

A. Monoecious plant with upper antheridial branch
B. Monoecious with upper archegonial branch
C. Sphagnum with independent sporophytic plant
D. Sphagnum with lower antheridial and archegonial branches

Answer

**Step-by-Step Solution:**

1. **Identify Peat Moss:**
- Peat moss is scientifically known as Sphagnum. It is a type of moss that belongs to the bryophyte group.

2. **Understand its State:**
- When Sphagnum moss is in a dry or decayed state, it is referred to as peat moss.

3. **Classify Peat Moss:**
- Sphagnum is classified as a bryophyte, which is a non-vascular plant.

4. **Examine the Life Cycle:**
- In bryophytes like Sphagnum, there is an alternation of generations. The dominant stage is the haploid gametophyte.

5. **Identify Gametophyte Characteristics:**
- Sphagnum has both male and female gametophytes that are independent and free-living.

6. **Distinguish Male and Female Structures:**
- The male reproductive structures (antheridia) and female reproductive structures (archegonia) are borne on separate branches.

7. **Analyze the Options:**
- The options provided include:
a) Monoecious plant with the upper antheridial branch
b) Monoecious plant with the upper archegonial branch
c) Sphagnum with independent saprophyte plant
d) Sphagnum with lower antheridial and archegonial branches

8. **Evaluate Each Option:**
- Option a and b are incorrect because Sphagnum can be either monoecious or dioecious, and the antheridia do not develop in the upper part.
- Option c is incorrect because Sphagnum is a gametophyte, not a saprophyte.
- Option d is correct as it accurately describes Sphagnum with lower antheridial and archegonial branches.

9. **Conclusion:**
- The correct answer is option D: Sphagnum with the lower antheridial and archegonial branches.
