The gametophytes in bryophytes produces biflagellate gametes (antherozoids) in _________and produces ovum (female gamete) in _______ .

Options

A. Antheridium, carpogonium
B. Anther, ovary
C. Archegonium, antheridium
D. Antheridium, archegonium

Answer

To answer the question regarding where gametophytes in bryophytes produce biflagellate gametes (antherozoids) and ovum (female gamete), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants that reproduce sexually and depend on water for fertilization. They are often found in damp and shaded environments.

2. **Identifying the Male Gamete**:
- In bryophytes, the male gamete is called antherozoid, which is biflagellate (has two flagella).
- The structure responsible for producing antherozoids is called the **antheridium**.

3. **Identifying the Female Gamete**:
- The female gamete in bryophytes is known as the ovum or egg.
- The structure that produces the ovum is called the **archegonium**.

4. **Filling in the Blanks**:
- Therefore, the gametophytes in bryophytes produce biflagellate gametes (antherozoids) in **antheridium** and produce ovum (female gamete) in **archegonium**.

5. **Final Answer**:
- The correct answer is: The gametophytes in bryophytes produce biflagellate gametes (antherozoids) in **antheridium** and produce ovum (female gamete) in **archegonium**.
