Answer 2

The tissue which provides nutrition to the developing embryo is formed by the fertilization of a male gamete with

a) Synergids

b) Antipodal cell

c) Secondary nucleus

d) Egg​

The tissue which provides nutrition to the developing embryo is formed by the fertilization of a male gamete with a secondary nucleus. (option c)

• When the male gamete comes in contact with the nucleus it forms a zygote.
• When another male gamete shows its fusion with two polar nuclei, in short, a secondary nucleus, then it forms a primary endosperm nucleus (PEN)
• PEN is triploid that is 3n, where n = number of chromosomes.
• As PEN provides nutrition and is formed from the secondary nucleus with the male gamete, so option c is correct with proper justification.
