16. Answer: Option
A is correct
Explanation:
Angiosperms = Flowering plants
They contain fruits, flowers, and pollen.
They exhibit double fertilization (Syngamy and triple fusion)
Syngamy = Fusion of male and female gametes (Haploid) to produce
the zygote (Diploid)
Triple fusion = Fusion of male nucleus with two polar nuclei to
produce triploid PEN

Question 4 How is angiosperm fertilization different than in gymnosperms? a. Angiosperms are the only plants to produce seeds after fertilization takes place. b. In angiosperms, the female gametophyte is present on bracts. c. In angiosperms, a sperm fuses with an egg to produce a zygote. d. Unlike other plants, angiosperms require water for fertilization to take place. e. Two fertilization events take place in angiosperms, producing a zygote and endosperm.
