Question

Angiosperms differ from other plants of plant kingdom in having
(1)Symgamy
(2) triple fission
(3) double fertilization
(4) both (2) and (3)​

Answer 1

Answer:

Answer is 3

Because double fertilisation = syngamy + triple fusion.

Syngamy is fusion of male gamete with egg cell

And triple fusion is fusion of male gamete with polar nuclei.

Together this is known as double fertilisation.

Answer 2

Concept: Fertilization process in angiosperms differ from other plants of plant kingdom.
Answer: The answer is option 4.
Explanation:
•Double fertilization involves fusion of two different components of the embryo sac with the two male gametes.
•First process of fusion results in a diploid zygote. The second process of fusion results in a triploid nucleus.
•The second fertilization process is called triple fusion as it involves fusion of three nuclei.

Hence, the correct answer of the question is option 4.
