Plasmogamy is fusion of:
Options
- ATwo haploid cells including their nuclei
- BTwo haploid cells without nuclear fusion
- CSperm and egg
- DSperm and two polar nuclei
Correct answer
B. Two haploid cells without nuclear fusion
Step-by-step solution
Fusion between the sperm and egg cell is called fertilization. During fertilization process the protoplasm between the two compatible gametes (gametes may be motile or non-motile) fuses which is called plasmogamy. Followed by plasmogamy the nuclei of both the gametes fuses together. This fusion of nuclei is called karyogamy.
