| Chapter | Cell: The Unit of Life (NEET PYQs 2016–2025) |
| Purpose | Chapterwise solved NEET previous year questions designed to strengthen NCERT concepts and improve exam performance. |
| Q1 Topic | Lysosomes – Structure, Formation and Functions |
| Key Learning | Lysosomes originate from the Golgi apparatus, while hydrolytic enzymes are synthesized by the rough endoplasmic reticulum (RER). |
| Q2 Topic | Mitochondria and ATP Production |
| Key Learning | Mitochondria are the powerhouse of the cell and are the primary site of aerobic respiration and ATP synthesis. |
| Q3 Topic | Chromosome Classification |
| Key Learning | Submetacentric chromosomes appear L-shaped during anaphase, while metacentric chromosomes form V-shapes. |
| Study Strategy | Complete the NCERT chapter first, then solve the PYQ workbook under timed conditions without checking answers. |
| Error Log Method | Record every incorrect or guessed question, revisit the corresponding NCERT concept, and highlight weak areas for revision. |
| Expected Benefit | Improved concept retention, identification of weak topics, and higher NEET Biology scores through focused revision. |

Q1. Which of the following statements is NOT correct? (NEET 2021)
A) Lysosomes are formed by the process of packaging in the endoplasmic reticulum.
B) Lysosomes have numerous hydrolytic enzymes.
C) The hydrolytic enzymes of lysosomes are active under acidic pH.
D) Lysosomes are membrane-bound structures.
Correct Answer: A
NCERT Focus Hint: Lysosomes are formed by the process of packaging in the Golgi apparatus, not the rough endoplasmic reticulum (RER). The RER synthesizes the enzymes, but the actual packaging into lysosomes happens at the trans-face of the Golgi complex.

Q1. Which of the following statements is NOT correct? (NEET 2021)
A) Lysosomes are formed by the process of packaging in the endoplasmic reticulum.
B) Lysosomes have numerous hydrolytic enzymes.
C) The hydrolytic enzymes of lysosomes are active under acidic pH.
D) Lysosomes are membrane-bound structures.
Correct Answer: A
NCERT Focus Hint: Lysosomes are formed by budding off from the Golgi apparatus, not directly from the endoplasmic reticulum, though the enzymes are synthesized by the RER.
Q2. Which of the following cell organelles is responsible for extracting energy from carbohydrates to form ATP? (NEET 2017)
A) Ribosome
B) Chloroplast
C) Mitochondrion
D) Lysosome
Correct Answer: C
NCERT Focus Hint: The mitochondrion is the power factory of the eukaryotic cell, acting as the primary site for aerobic respiration and ATP generation.
Q3. Select the incorrect match from the following options: (NEET 2020)
A) Submetacentric chromosomes – L-shaped chromosomes
B) Allosomes – Sex chromosomes
C) Submetacentric chromosomes – Centromere slightly away from the middle
D) Lampbrush chromosomes – Oocytes of amphibians
Correct Answer: A
NCERT Focus Hint: During anaphase movement, submetacentric chromosomes present a J-shape or L-shape depending on arm length ratios, but metacentric positions yield distinct V-shapes. Always double-check structural classifications.
🛠️ Step-by-Step Guide to Using This PYQ PDF
To get the maximum score increase out of this free download, do not treat it like a casual reading book. Follow this topper-verified 3-step system:
The Blind Attempt:
Finish reading Chapter 8 of your Class 11 NCERT textbook completely. Close the book, set a timer (allocate roughly 45 seconds per question), and attempt this PDF workbook without looking at the answer keys.
The Error Log:
Circle every question you answered incorrectly or marked based on a guess. Open your textbook and locate the exact page where that concept is explained. Highlight that section in red—it is your personal weak spot.
The Revision Loop:
Re-attempt those flagged mistake questions exactly 7 days later. This method shifts your understanding from short-term memory into long-term retention.
