Plant Reproduction Matching: Intra Ovarian Pollination, Double Fertilization, Syngamy, Necrohormone Theory Scientists
Mastering scientists behind key plant reproduction processes is essential for exams like CUET Botany. This guide reveals the correct matches for List I processes with List II scientists.
Correct Answer
The correct option is (A) – (IV), (B) – (III), (C) – (II), (D) – (I).
Intra ovarian pollination links to Kanta (IV), double fertilization to S. Nawaschin (III), syngamy to E. Strasburger (II), and necrohormone theory to L. Haberlandt (I).
Processes and Scientists
These terms relate to angiosperm reproduction and pollen-pistil interactions.
-
Intra ovarian pollination (Kanta): Artificial technique where pollen is applied directly inside the ovary, bypassing stigma for distant species hybridization.
-
Double fertilization (S. Nawaschin): Discovery in 1898 of one sperm fusing with egg (zygote) and another with polar nuclei (endosperm), unique to angiosperms.
-
Syngamy (E. Strasburger): Fusion of male and female gametes to form zygote, termed by Strasburger in plant studies.
-
Necrohormone theory (L. Haberlandt): Proposal that dying synergid cells release signals (“necrohormones”) to burst pollen tube for sperm release.
Option Analysis
Options test historical attributions in reproductive biology.
Option A B C D Status 1 I II III IV Incorrect: A mismatches (Haberlandt not pollination); B wrong (Strasburger not double fert.). 2 I III II IV Incorrect: A wrong; C/D swapped (syngamy Strasburger, necrohormone Haberlandt). 3 I II IV III Incorrect: Multiple mismatches, e.g., A (Haberlandt), C (Kanta not syngamy). 4 IV III II I Correct: Precise links—Kanta (pollination), Nawaschin (double fert.), Strasburger (syngamy), Haberlandt (necrohormone). Exam Strategy
Memorize via mnemonics: Kanta’s Intra, Nawaschin’s Double, Strasburger’s Syngamy, Haberlandt’s Necro. Practice matching for NEET/CUET retention.
