The male sex organ that produces antherozoids is known as

Options

A. Gametophyte
B. Antheridium
C. Sporophyte
D. Archegonium

Answer

To answer the question "The male sex organ that produces antherozoids is known as," we will analyze the options provided: gametophyte, antheridium, sporophyte, and archegonia.

### Step-by-Step Solution:

1. **Understanding the Options:**
- **Sporophyte:** This is the diploid multicellular stage in the life cycle of plants and algae. It develops from a zygote and is not involved in producing male gametes. Therefore, this option is incorrect.

2. **Analyzing Gametophyte:**
- **Gametophyte:** This is the haploid multicellular phase in the life cycle of plants and algae. It develops from a haploid spore and is responsible for producing gametes. However, it is not specifically a male sex organ, so this option is also incorrect.

3. **Examining Archegonium:**
- **Archegonium:** This is the female sex organ in the gametophyte phase of certain plants. It produces and contains the ovum (female gamete). Since we are looking for the male sex organ, this option is not correct.

4. **Identifying Antheridium:**
- **Antheridium:** This is the male sex organ in the gametophyte phase of plants. It is a haploid structure that produces and contains male gametes, known as antherozoids. This option is correct.

### Conclusion:
The male sex organ that produces antherozoids is known as **antheridium**.
