NEET 2024 Biology Photosynthesis Questions

Use this page to connect the official 2024 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

pigments, light reactions, carbon fixation, photorespiration and limiting factors.

Original practice preview

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

Example 1 · difficulty 2/5

What is the combined significance of accessory pigments such as chlorophyll b, xanthophylls and carotenoids?

A. They replace chlorophyll a as the reaction-centre pigment in every photosystem.
B. They broaden the usable range of light and can protect chlorophyll a from photo-oxidation.
C. They absorb only green light and convert it directly into carbon dioxide.
D. They function solely as stored respiratory substrates in the stroma.

Example 2 · difficulty 2/5

What information is represented by an absorption spectrum of a photosynthetic pigment?

A. The rate of carbon dioxide fixation at different temperatures
B. The amount of oxygen released at different carbon dioxide concentrations
C. The relative amount of light absorbed by the pigment at different wavelengths
D. The number of chloroplasts formed under different light intensities

Example 3 · difficulty 2/5

Which measurement would be most appropriate for constructing an action spectrum of photosynthesis?

A. Pigment concentration measured after exposure to one wavelength
B. Leaf thickness measured in plants grown under different colours
C. Percentage of each wavelength reflected by a chlorophyll solution
D. Rate of oxygen evolution measured separately under equal intensities of different wavelengths

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 2024 Biology Photosynthesis 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 2024 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.
