NEET 2026 Biology Plant Physiology Questions
Use this page to connect the official 2026 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 2/5
Which chloroplast compartment-function pairing is correct?
- A. Outer envelope membrane — main site of carbon dioxide reduction
- B. Thylakoid membranes — light reactions; stroma — enzymatic carbon fixation reactions
- C. Thylakoid lumen — main location of starch synthesis from carbon dioxide
- D. Stroma lamellae — storage site containing no photosynthetic machinery
Example 3 · difficulty 2/5
Which description of the internal membrane system of a chloroplast is accurate?
- A. Cristae are stacked to form grana inside chloroplasts.
- B. The chloroplast envelope folds inward to form all grana directly.
- C. Flattened thylakoid sacs form grana, and different grana are connected by stroma lamellae.
- D. The stroma is arranged as membrane-bound discs called grana.
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 2026 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 2026 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.
