NEET 2020 Biology Questions

Use this page to connect the official 2020 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.

Original practice preview

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

Example 1 · difficulty 3/5

Colostrum, the yellowish fluid secreted by a mother during the initial days of lactation, protects the breast-fed infant against several infections. The immunoglobulin chiefly responsible for this protection is:

  • A. IgM
  • B. IgE
  • C. IgG
  • D. IgA

Example 2 · difficulty 1/5

In grasses, grazing animals often remove the shoot tip, yet the leaves resume growth and the plant recovers quickly. Which meristematic tissue accounts for this regeneration?

  • A. Apical meristem, because it shifts its position to the freshly cut end
  • B. Intercalary meristem, present at the bases of internodes and leaf blades
  • C. Lateral meristem, because it adds new cells along the length of the leaf
  • D. Root apical meristem, which pushes new cells upward into the shoot

Example 3 · difficulty 2/5

Among the four components of xylem, which one remains living at maturity and can store starch, fats and tannins?

  • A. Vessels

  • C. Xylem fibres
  • D. Xylem parenchyma

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2020 Biology 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 2020 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.
