In some plants, the female gamete develops into embryo without fertilization. This phenomenon is known as (NEET 2019)
Answer: (D) (4) Parthenogenesis. Answer: D.
- A.(1) Autogamy
- B.(2) Parthenocarpy
- C.(3) Syngamy
- D.(4) Parthenogenesis✓
Correct Answer
(D) (4) Parthenogenesis
Solution & Explanation
Answer: D. Development of the female gamete (egg) into an embryo without fertilisation is parthenogenesis. Autogamy is self-pollination, syngamy is egg–male gamete fusion, and parthenocarpy is fruit formation without fertilisation (not embryo from egg). NCERT describes apomictic seed formation in which the (diploid) egg cell develops into the embryo without fertilisation, the closest grounding for this answer. NCERT: Ch 1, p.22, lines 44-46 — "In some species, the diploid egg cell is formed without reduction division and develops into the embryo without fertilisation."
