Verified Answer
What are the three main steps involved in the sexual cycle in sequence...
The sexual cycle involves the following three steps: (i) Fusion of protoplasms between two motile or non-motile gametes called plasmogamy. (ii) Fusion of two nuclei called karyogamy. (iii) Meiosis in zygote resulting in haploid spores

Understanding the Sexual Cycle
The sexual cycle involves a series of events that lead to reproduction, particularly in fungi and certain plants. The correct sequence is Plasmogamy, Karyogamy, and Meiosis.
1. Plasmogamy
- This is the first step where the cytoplasm of two compatible mating types fuse together.
- Plasmogamy results in the formation of a dikaryotic cell, meaning it has two distinct nuclei from each parent.
2. Karyogamy
- Following plasmogamy, karyogamy occurs, which is the fusion of the two nuclei to form a diploid nucleus.
- This step is crucial as it combines genetic material from both parents, leading to genetic variation in the offspring.
3. Meiosis
- The final step is meiosis, where the diploid nucleus undergoes division to produce haploid spores.
- These spores can then germinate and develop into new organisms, completing the sexual cycle.
Conclusion
In summary, the sexual cycle progresses in a specific order:
- Plasmogamy initiates the process by fusing the cytoplasm.
- Karyogamy follows, leading to the fusion of nuclei.
- Meiosis concludes the cycle by producing haploid spores.
This sequence (Plasmogamy → Karyogamy → Meiosis) is essential for genetic diversity and the continuation of species. Understanding these steps is critical for topics related to reproduction and genetics, especially in the context of NEET preparation.
