NEET 2022 Biology Plant Physiology Questions
Use this page to connect the official 2022 paper with current Biology practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
photosynthesis, respiration, growth and hormonal control.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 4/5
During oxidative phosphorylation, FADH2 yields fewer ATP molecules than NADH because FADH2
- A. enters the electron transport chain at complex II, bypassing complex I, so fewer protons are pumped across the inner membrane
- B. is unable to transfer its electrons to ubiquinone
- C. gets oxidised within the mitochondrial matrix without ever engaging the electron transport chain
- D. donates a single electron rather than a pair of electrons
Example 3 · difficulty 2/5
The respiratory pathway is described as an amphibolic pathway because it
- A. functions only in the presence of oxygen
- B. participates in both the breakdown and the synthesis of organic compounds
- C. is distributed between the cytoplasm and the mitochondria
- D. generates both ATP and reduced coenzymes simultaneously
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2022 Biology Plant Physiology 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.
