Which of the following is a correct sequence of processes that takes place when a flowering plant reproduces?
A) meiosis → fertilization → ovulation → germination
B) fertilization → meiosis → nuclear fusion → formation of embryo and endosperm
C) meiosis → pollination → nuclear fusion → formation of embryo and endosperm
D) growth of pollen tube → pollination → germination → fertilization
E) meiosis → mitosis → nuclear fusion → pollen

Question

The correct sequence of processes that takes place when a flowering plant reproduces is as follows: meiosis to produce haploid gametes (pollen and egg cells) → pollination (transfer of pollen from anther to stigma) → nuclear fusion (fertilization) of the haploid egg cell and sperm cell to form a diploid zygote → formation of embryo and endosperm. Choice A has the correct events but in the wrong order. Choice B has the correct events but in the wrong order and also includes "nuclear fusion," which is not a distinct process from fertilization. Choice D has some of the correct events, but in the wrong order and it also includes "growth of pollen tube," which occurs during pollination, not after it. Choice E includes "mitosis," which is not involved in sexual reproduction in plants.
