Question
Once the pollen tube reaches the egg cell in conifers,Multiple choice question.one sperm cell fertilizes the egg cell to form the zygote, and the other sperm cell disintegrates.one sperm cell fertilizes the egg cell to form the zygote, and the other sperm cell fertilizes other nuclei to form the endosperm.two sperm cells fertilize one egg cell, forming a triploid zygote.
Solution
The correct answer is: one sperm cell fertilizes the egg cell to form the zygote, and the other sperm cell disintegrates.
In conifers, the process of fertilization involves the transfer of pollen from the male cone to the female cone. Once the pollen reaches the female cone, it germinates to form a pollen tube that grows towards the egg cell. The pollen tube carries two sperm cells, one of which will fertilize the egg cell to form the zygote, which will eventually develop into the embryo of the new plant. The other sperm cell does not fertilize any other cell and disintegrates. This is different from the process in flowering plants, where the second sperm cell fertilizes other nuclei to form the endosperm.
