A researcher observes a plant species where the generative cell undergoes mitosis before pollination, resulting in two sperm cells within the pollen grain. How might this unusual characteristic affect double fertilization?
Prevent double fertilization from occurring.
Enhance the efficiency of double fertilization.
Potentially lead to the fertilization of both the egg cell and a synergid, disrupting endosperm development.
Have no significant impact on the process of double fertilization.
