Algae, bryophyte, and pteridophytes resemble with each other in which one of the following feature?

Options

A. Gametophytic plant body
B. Dependence on water for fertilization
C. Heteromorphic alternation of generation
D. Presence of embryo

Answer

To solve the question regarding the similarities between algae, bryophytes, and pteridophytes, we will analyze the given options step by step.

### Step-by-Step Solution:

1. **Understanding the Groups**:
- **Algae**: Simple, primarily aquatic organisms that can perform photosynthesis. They reproduce both sexually and asexually.
- **Bryophytes**: Non-vascular land plants, such as mosses, that require water for reproduction. They have a dominant gametophyte stage.
- **Pteridophytes**: Vascular plants like ferns that also require water for reproduction and have a dominant sporophyte stage.

2. **Analyzing Each Option**:
- **Option 1: Gametophytic Plant Body**:
- This is true for bryophytes, which have a dominant gametophyte stage. However, pteridophytes have a dominant sporophyte stage, so this option is not correct.

- **Option 2: Dependence on Water for Fertilization**:
- All three groups (algae, bryophytes, and pteridophytes) require water for the fertilization process. This is a key similarity, making this option a strong candidate.

- **Option 3: Heteromorphic Alternation of Generations**:
- This phenomenon is not present in bryophytes, as they do not exhibit a significant alternation of generations like pteridophytes do. Thus, this option is ruled out.

- **Option 4: Presence of Embryo**:
- Embryos are present in both bryophytes and pteridophytes but absent in algae. Therefore, this option is also incorrect.

3. **Conclusion**:
- Based on the analysis, the only feature that is common among algae, bryophytes, and pteridophytes is their dependence on water for fertilization.

### Final Answer:
The correct answer is **Option 2: Dependence on water for fertilization**.
