A plant shows rhizoids and is haploid. It needs water to complete its lifecycle because the male gametes are motile. Identify the group to which it belongs.

Options

A. Pteridophyte
B. Gymnosperm
C. Monocot
D. Bryophytes

Answer

To solve the question, we need to analyze the characteristics given and identify the group of plants that fits these criteria.

### Step-by-Step Solution:

1. **Identify Key Characteristics**: The question states that the plant shows rhizoids, is haploid, needs water to complete its lifecycle, and has motile male gametes.

2. **Understand Rhizoids**: Rhizoids are root-like structures found in certain plants that help anchor them to the substrate. They are typically found in non-vascular plants such as mosses and liverworts.

3. **Recognize the Haploid Stage**: The term "haploid" indicates that the plant is in its gametophyte stage, which is the dominant stage in certain groups of plants.

4. **Water Dependency for Fertilization**: The need for water for fertilization suggests that the male gametes (sperms) are motile and swim through water to reach the egg. This is a characteristic feature of bryophytes.

5. **Conclusion**: Given these characteristics, the plant in question belongs to the group known as **Bryophytes**. Bryophytes are often referred to as the amphibians of the plant kingdom because they require water for reproduction.

### Final Answer:
The group to which the plant belongs is **Bryophytes**.
