Question:
Select the INCORRECT statement from the following with respect to double fertilization.
Select the INCORRECT statement from the following with respect to double fertilization.
Show Hint
Delivery of non-motile gametes by pollen tube has a different name than mesogamy.
Updated On: Nov 12, 2026
- The zygote develops into an embryo
- Syngamy is a type of generative fertilization
- Triple fusion is a type of vegetative fertilization
- Non-motile male gametes are carried through the pollen tube and it is called mesogamy.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Double fertilisation has syngamy and triple fusion.
Step 2: Check the statements
The zygote develops into the embryo.\nSyngamy is generative fertilisation and triple fusion is vegetative fertilisation.
Step 3: Conclusion
Carrying non-motile gametes by a pollen tube is siphonogamy; mesogamy refers to entry through the integument or funicle, so D is incorrect.
Final Answer:
Statement D is incorrect. \[ \boxed{\text{(D) }\text{Non-motile male gametes are carried through the pollen tube and it is called mesogamy}} \]
