Read the following five statements (A-E) and answer as asked next to them
(A) In Equisetum the female gametophyte is retained on the parent sporophte
(B) In ginkgo male gametophyte is not independent
(C) Sexual reproduction in Volvox is isogamous
(D)The sporophyte in Riccia is more developed than that in polytrichum
(E) The spores of slime moulds lack cell walls
How many of the above statements are correct

Options

A. Four
B. One
C. Two
D. Three

Answer

To determine how many of the provided statements (A-E) are correct, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement A**: "In Equisetum the female gametophyte is retained on the parent sporophyte."
- **Analysis**: Equisetum is a pteridophyte where the female gametophyte is actually free-living and not retained on the sporophyte.
- **Conclusion**: This statement is **incorrect**.

2. **Statement B**: "In Ginkgo male gametophyte is not independent."
- **Analysis**: In Ginkgo, the male gametophyte develops within the pollen grain and is not free-living, meaning it is dependent on the sporophyte for its development.
- **Conclusion**: This statement is **correct**.

3. **Statement C**: "Sexual reproduction in Volvox is isogamous."
- **Analysis**: Volvox exhibits anisogamy, where the male gametes are smaller and motile, while the female gametes are larger and non-motile.
- **Conclusion**: This statement is **incorrect**.

4. **Statement D**: "The sporophyte in Riccia is more developed than that in Polytrichum."
- **Analysis**: Riccia is a liverwort, and its sporophyte is less developed compared to that of Polytrichum, which is a moss.
- **Conclusion**: This statement is **incorrect**.

5. **Statement E**: "The spores of slime molds lack cell walls."
- **Analysis**: Spores of slime molds do have cell walls that are resistant and can survive for long periods.
- **Conclusion**: This statement is **incorrect**.

### Summary of Findings:
- Statement A: Incorrect
- Statement B: Correct
- Statement C: Incorrect
- Statement D: Incorrect
- Statement E: Incorrect

### Final Answer:
Only **one statement (B)** is correct.
