Haplontic life cycle is represented by

Options

A. Volvox
B. Cycas
C. Selaginella
D. Salvinia

Answer

### Step-by-Step Solution:

1. **Understanding Haplontic Life Cycle**:
- The term "haplontic" is derived from "haploid," which refers to the single N condition of cells. In this life cycle, the dominant phase is the haploid stage.

2. **Formation of Zygote**:
- In the haplontic cycle, haploid gametes (male and female) fuse to form a diploid zygote (2N). This zygote is the result of the fusion of male and female gametophytes.

3. **Meiosis in Zygote**:
- The diploid zygote undergoes meiosis, which is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid spores.

4. **Germination of Spores**:
- These haploid spores germinate and develop into the gametophyte generation, which is the dominant stage in the haplontic life cycle.

5. **Examples of Organisms**:
- The haplontic life cycle is primarily observed in lower plant structures, particularly in certain algae. Two notable examples of algae that exhibit this life cycle are **Volvox** and **Spirogyra**.

6. **Conclusion**:
- Therefore, the haplontic life cycle is represented by algae, making it the correct answer to the question.
