photosynthesis, respiration, growth and hormonal control.

Original practice preview

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

Example 1 · difficulty 1/5

In T.W. Engelmann's classic experiment, a filamentous green alga was illuminated with light split into its spectral components while suspended in a culture of aerobic bacteria. The bacteria were observed to cluster mainly in which region?

A. Uniformly along the entire length of the filament, since oxygen diffuses everywhere
B. Only in the green region, because the alga appears green and must be most active there
C. Mainly in the regions of blue and red light of the split spectrum
D. Mainly in the violet and orange regions, away from the centre of the spectrum

Example 2 · difficulty 2/5

Which of the following statements regarding photosynthetic pigments is correct?

A. Chlorophyll a acts as the reaction centre pigment of both PS I and PS II and is called the chief pigment of photosynthesis
B. Chlorophyll b is indispensable and is present in every organism that carries out photosynthesis
C. Carotenoids show their maximum absorption in the far-red region around 700 nm
D. Xanthophylls protect chlorophyll from photo-oxidation and can directly transfer electrons to NADP+

Example 3 · difficulty 3/5

Consider the following statements about cyclic photosphosphorylation: (i) Only PS I is functionally involved (ii) Both ATP and NADPH + H+ are produced (iii) There is no evolution of O2 (iv) Excited electrons return to P700 after travelling through an electron transport chain Which combination is correct?

A. (i) and (ii)
B. (i), (iii) and (iv)
C. (ii) and (iii)
D. (iii) and (iv) only

Frequently asked questions

Are these official NEET 2016 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 2016 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.
