After fertilization in plants, the zygote develops into

Step 1: Analyze the question The question asks what the zygote itself becomes after fertilization in a flowering plant.

Step 2: Explain the concept In double fertilization in angiosperms:

• One male gamete (n) fuses with the egg cell (n) to form the zygote (2n).
• The second male gamete fuses with the two polar nuclei to form the primary endosperm nucleus (3n), which develops into the endosperm.

After fertilization, the following changes occur:

• Zygote → embryo (plumule, radicle, cotyledons)
• Primary endosperm nucleus → endosperm
• Ovule → seed
• Ovary → fruit

Step 3: Work through the options

• A. Fruit: This develops from the ovary, not the zygote.
• B. An embryo: The zygote divides by mitosis to form the embryo. Correct.
• C. Seed: This develops from the whole ovule, which contains the embryo, endosperm, and seed coat. The zygote is only one part of it.
• D. Endosperm: This comes from the fusion of a male gamete with the polar nuclei, not from the zygote.

Step 4: Answer The zygote develops into the embryo, which is option B.

Tip: Remember the pairings, "Zygote → Embryo, Ovule → Seed, Ovary → Fruit." Exam questions often mix up these three, so check which part of the flower each one comes from. Keep practising, you are doing well!
