The cell chapters from NCERT Class 11 Biology are short but heavily tested in NEET, often word-for-word from the textbook. This set covers cell theory, prokaryotic and eukaryotic cells, cell organelles and their functions, the cell cycle, mitosis and the sub-stages of meiosis.
How to practise: read each question and tap the option you think is correct. You will see right away whether you got it, along with a short explanation, and your score is tracked at the bottom of the screen. This set has 15 questions.
Topics covered in this set
- Cell theory
- Prokaryotic vs eukaryotic cells
- Membrane structure and organelles
- Ribosome types
- Cell cycle and interphase
- Mitosis and meiosis sub-stages

Quick revision notes
- Virchow: omnis cellula-e cellula.
- 70S in prokaryotes, mitochondria and chloroplasts; 80S in eukaryotic cytoplasm.
- Fluid mosaic model: Singer and Nicolson (1972).
- DNA doubles in S phase; G₀ is the quiescent stage.
- Meiosis I prophase: leptotene, zygotene (synapsis), pachytene (crossing over), diplotene (chiasmata), diakinesis.
Frequently asked questions
Are these NEET previous year questions?
No, they are original practice questions based on the NCERT Class 11 chapters "Cell: The Unit of Life" and "Cell Cycle and Cell Division".
Is NCERT enough for NEET Biology?
NCERT is the primary source for NEET Biology. Read it line by line and practise MCQs to apply the facts.
How do I remember the sub-stages of prophase I?
Use the order Leptotene, Zygotene, Pachytene, Diplotene, Diakinesis and attach one key event to each, as in the revision notes above.
