Question

Fertilization in the flowering plants produces

• A. Embryo
• B. Endosperm
• C. Nucellus
• D. Both A and B

Answer 1

The correct option is D

Both A and B

The correct option is D

Explanation of incorrect option:

1. Fertilization occurs when the male gamete present in pollen grain joins with the female gamete or egg present in the ovule
2. During fertilization, one male gamete fuses with the egg to form the diploid zygote is called syngamy.
3. The diploid zygote finally develops into the embryo.
4. The other male gamete fuses with the two polar nuclei to form the triploid ($3N$) primary endosperm nucleus process is called triple fusion.
5. The mechanism involving two acts of fertilization in an embryo sac is called double fertilization.

Option A:

1. The one male gamete that fuses with the egg to form the diploid zygote.
2. The diploid zygote finally develops into the embryo.

Option B:

1. The other male gamete fuses with the two polar nuclei to form the triploid($3N$) primary endosperm nucleus.
2. The primary endosperm nucleus developed into the endosperm.

Option C:

1.Each ovule consists of one or two protective envelopes called integuments and a mass of parenchymatous cells called nucellus.

Final answer: Fertilization in the flowering plants produces both embryo and endosperm.
