Question:
Double fertilisation is a characteristic feature of:
Double fertilisation is a characteristic feature of:
Show Hint
Double fertilization = Syngamy + Triple Fusion. This only happens in flowering plants (Angiosperms).
Updated On: May 5, 2026
- Gymnosperms
- Algae
- Angiosperms
- Pteridophytes
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Double fertilization is a complex fertilization mechanism involving the joining of a female gametophyte with two male gametes.
Step 2: Meaning
One male gamete fertilizes the egg cell to form a zygote (syngamy), while the other fuses with two polar nuclei to form the triploid primary endosperm nucleus (triple fusion).
Step 3: Analysis
Algae and Pteridophytes have simpler fertilization processes. Gymnosperms have single fertilization. This unique "double" event is exclusive to flowering plants.
Step 4: Conclusion
Therefore, double fertilization is the defining characteristic feature of Angiosperms. Final Answer: (C)
