How double fertilisation happens

Question 1

Question 2

this is an interesting question Double fertilization is a complex process where out of two sperm cells, one fuses with the egg cell and the other fuses with two polar nuclei which result in a diploid (2n) zygote and a triploid (3n) primary endosperm nucleus (PEN) respectively.

Question 3

sperm cell 怎么enter embryo 再fuse with nucleus，micropyle有pore让它们进去吗？

Question 4

These enzymes then begin to digest the zona pellucida and allow the sperm to tunnel toward the egg's plasma membrane. When the sperm cell finally reaches the egg cell, the plasma membranes of the two cells fuse together and the sperm releases its genetic material into the egg.

Question 5
