Cell: The Unit of Life

Cell theory, prokaryotic and eukaryotic cells, and the organelles, from ribosomes and ER to mitochondria and the nucleus, sit in this chapter. NEET keeps it recall based, testing organelle functions and prokaryote versus eukaryote differences in single lines.

Exam rules change between cycles. Confirm dates, syllabus and pattern against NTA's official site. We are not NTA.

Weightage: what the paper actually did

Cell: The Unit of Life carried 4 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Question 1 · NEET 2026

Which one of the following is the site for active ribosomal RNA synthesis?
  1. A.Centrosome
  2. B.Chromatin
  3. C.Nucleolus
  4. D.Kinetochore
Answer and explanation

Answer: C

The nucleolus is a non-membrane-bound region within the nucleus and is the site of active ribosomal RNA (rRNA) synthesis and assembly of ribosomal subunits. The centrosome organises spindle fibres, chromatin is the DNA-protein complex carrying genes, and the kinetochore is the protein plate on the centromere for spindle-fibre attachment. Why the other options are wrong: - (A) The centrosome forms spindle fibres during division. - (B) Chromatin carries genetic material but is not the rRNA synthesis site. - (D) The kinetochore anchors spindle fibres at the centromere.

Question 2 · NEET 2026

Non-membrane bound cell organelles found in both prokaryotic and eukaryotic cells are ______.
  1. A.Ribosomes
  2. B.Lysosomes
  3. C.Centrosomes
  4. D.Mitochondria
Answer and explanation

Answer: A

Ribosomes lack a surrounding membrane and are present in both prokaryotic (70S) and eukaryotic (80S) cells. Lysosomes and mitochondria are membrane-bound and absent in prokaryotes, while the centrosome is found only in animal (eukaryotic) cells, so only ribosomes fit.

How to practise Cell: The Unit of Life

Chapter by chapter, against real past-paper questions, on a screen: NEET is computer based from 2027. Read the chapter once, then attempt its PYQs until your accuracy stops climbing, and let the wrong answers tell you which lines to reread. If the chapter keeps refusing to stick, that has its own guide. There is also a free 12-question mock on the exam screen.
