Question
What is double fertilisation? Mention its significance.
✓
Answer
Double fertilization is the joining of a female gametophyte with two male gametes. One sperm fertilizes the egg cell and the other sperm combines with the two polar nuclei of the large central cell of the embryo sac. This helps in providing enough nutrition to the embryo during seed germination.
