Select the INCORRECT statement from the following with respect to...
Select the INCORRECT statement from the following with respect to double fertilization.
Options
- AThe zygote develops into an embryo
- BSyngamy is a type of generative fertilization
- CTriple fusion is a type of vegetative fertilization
- DNon-motile male gametes are carried through the pollen tube and it is called mesogamy.
Correct answer
D. Non-motile male gametes are carried through the pollen tube and it is called mesogamy.
Step-by-step solution
The zygote develops into an embryo after syngamy. This is a correct statement.
Syngamy involves the fusion of one male gamete with the egg cell to form a diploid zygote. It is also known as generative fertilization. This is a correct statement.
Triple fusion involves the fusion of the second male gamete with the diploid secondary nucleus to form a triploid primary endosperm nucleus. It is also known as vegetative fertilization. This is a correct statement.
The transport of non-motile male gametes to the female gamete through a pollen tube is called siphonogamy. Mesogamy refers to the entry of the pollen tube into the ovule through the integuments or funiculus. Therefore, this statement is incorrect.
Answer: Non-motile male gametes are carried through the pollen tube and it is called mesogamy.
