Which of the following statement in incorrect regarding bryophytes?

Options

A. They are dependent on water for sexual reproduction.
B. The main plant body is diploid
C. They usually occur in damp, humid and shady localities.
D. They play an important role in plant succession on barc rocks

Answer

To determine which statement is incorrect regarding bryophytes, we can analyze each statement provided:

1. **They are dependent on water for sexual reproduction.**
- **Analysis:** This statement is true. Bryophytes are often referred to as the amphibians of the plant kingdom because they require water for their reproductive processes, particularly for the movement of sperm to the egg.

2. **The main plant body is diploid.**
- **Analysis:** This statement is incorrect. In bryophytes, the main plant body is haploid (n), which is known as the gametophyte. The sporophyte (2n) is dependent on the gametophyte and is not the main plant body.

3. **They usually occur in damp, humid, and shady localities.**
- **Analysis:** This statement is true. Bryophytes thrive in moist environments, which is essential for their reproductive processes and overall survival.

4. **They play an important role in the plant's succession on bare rock.**
- **Analysis:** This statement is also true. Bryophytes contribute to soil formation and ecological succession by breaking down rocks and contributing organic material.

**Conclusion:** The incorrect statement regarding bryophytes is that the main plant body is diploid.
