Q50.Arrange the following in decreasing order (size).
A. Mitochondria
B. Proteins
C. Ribosomes
D. Human egg
E. Nucleus
Choose the correct answer from the options given below :
(1) D, A, C, B, E
(2) D, A, C, E, B
(3) D, E, C, A, B
(4) D, E, A, C, B
Human egg is largest, followed by nucleus, mitochondria, ribosomes, then proteins—correct order D, E, A, C, B (option 4).
Option Analysis
-
Option (1) D, A, C, B, E: Wrong—nucleus (~5-10 μm) larger than mitochondria (~1-2 μm length), so E > A.
-
Option (2) D, A, C, E, B: Wrong—nucleus (E) bigger than mitochondria (A) and ribosomes (C ~25 nm).
-
Option (3) D, E, C, A, B: Wrong—mitochondria (A, 1-10 μm) larger than ribosomes (C, 20-30 nm).
-
Option (4) D, E, A, C, B: Correct—D (~100 μm), E (5-10 μm), A (1-10 μm), C (25 nm), B (1-10 nm typical).
Approximate Sizes
Confused how to arrange mitochondria proteins ribosomes human egg nucleus from largest to smallest? NEET Q50 demands precise cell size knowledge—this guide delivers option (4) D-E-A-C-B with exact measurements for exam success.
Cell Component Sizes Ranked
Human egg (ovum) dominates at ~100-120 μm diameter—visible to naked eye. Nucleus follows at 5-10 μm, the cell’s control center. Mitochondria measure 1-10 μm long (often 1-2 μm). Ribosomes are tiny 20-30 nm. Proteins range 1-10 nm (e.g., hemoglobin ~5.5 nm).
Why This Order Matters
-
Human egg: Largest human cell for nutrient storage.
-
Nucleus: Houses DNA, largest eukaryotic organelle.
-
Mitochondria: Rod-shaped ATP producers.
-
Ribosomes: Non-membranous protein synthesizers.
-
Proteins: Building blocks, nanoscale.
NEET Exam Strategy
-
Remember: Egg > Nucleus > Mitochondria > Ribosome > Protein.
-
Mnemonic: Egg Never Makes Ribosomes Protect.
-
Common trap: Mitochondria vs nucleus—nucleus wins consistently.
