Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 2/5

During double fertilization, the primary endosperm nucleus (PEN) is produced by the fusion of:

A. the egg cell with one male gamete
B. two male gametes released by one pollen tube
C. one male gamete with the two polar nuclei of the central cell
D. a synergid with one male gamete

Example 2 · difficulty 4/5

An angiosperm plant must produce 160 mature pollen grains and 40 ovules. The minimum number of meiotic divisions required in the anthers and in the ovules respectively will be:

A. 160 and 40
B. 40 and 40
C. 40 and 160
D. 80 and 20

Example 3 · difficulty 3/5

Cleistogamous flowers offer a plant a distinct advantage because they:

A. attract a broad spectrum of insect pollinators
B. promote cross-pollination and generate greater genetic variability
C. guarantee seed formation even when pollinators are unavailable
D. keep the anthers and stigma exposed to wind and water currents

The evidence-first practice loop

1. Verify provenanceOfficial paper and final key before accepting a PYQ label.

Frequently asked questions

Are these official NEET 2022 Biology Reproduction PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2022 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
