Answer:

3

Explanation:

i think the should be both assertion and reason are correct but reason is not the correct explanation of assertion

Answer 2

The Assertion is true and the reason is the correct explanation of the assertion.

Why only in angiosperms does double fertilization occur?

• Because the ovary develops into fruit and the ovule develops into a seed with an embryo and primary endosperm inside of it, double fertilization is regarded as a singular event in the plant kingdom.
• One male gamete joins the egg cell during double fertilization to create a diploid zygote.

Only angiosperms have triple fusion:

• The fertilization of the two polar nuclei in the embryo sac is known as triple fusion.
• It happens when angiosperms undergo double fertilization.
• The two polar nuclei present in the core cell of the embryo are fertilized by one sperm cell, while the egg cell in the embryo sac is fertilized by the other sperm cell.
• The female gamete is fused by one male gamete, while the secondary nucleus is fused by the other male gamete.
• This method is known as double fertilization because it involves two male gametes and results in double fertilization.
• The process is known as triple fusion because it involves three gametes.
