In angiosperms, after the pollen tube enters the synergid, what is the function of the two male gametes?
Syngamy and triple fusion
Formation of the embryo sac
Development of the pollen tube
Initiation of meiosis
Which statement correctly describes the fate of the male gametes discharged in the synergid?
One participates in syngamy, and the other participates in triple fusion.
Both participate in syngamy.
Both participate in triple fusion.
Both degenerate.
Double fertilization in angiosperms involves the fusion of the male gametes with which structures?
Egg cell and polar nuclei
Two egg cells
Two polar nuclei sets
Synergids and antipodals
If one male gamete fuses with the egg cell, what is the fate of the other male gamete in the process of double fertilization?
Fuses with the polar nuclei to form the primary endosperm nucleus
Fuses with another egg cell
Degenerates
Forms the seed coat
Which of the following groups of plants exhibits double fertilization?
Angiosperms
Gymnosperms
Pteridophytes
Bryophytes
Double fertilization is a key event in the reproductive cycle of:

Triple fusion
Pollination
Which structure is formed as a result of the fusion of one male gamete with the polar nuclei during double fertilization?
Endosperm
Zygote
Embryo
Seed coat
The male gametophyte in angiosperms is responsible for producing:
Two female gametes
One male and one female gamete
Two male and one female gamete
Two male gametes
The process of double fertilization in angiosperms involves the fusion of one male gamete with the egg cell and the other with the:
