Question

Which of the following alternatives will replace the question mark?

Atom, Molecule, Cell, ?

1. A. Tissue (Correct answer)
2. B. Proton
3. C. System
4. D. Gene

Correct Answer

Option A — Tissue

Detailed Solution & Explanation

The correct answer is Tissue.

Key Points

• The sequence is the hierarchy of biological organisation, each level built from the one before.
• Atom → Molecule → Cell → Tissue → Organ → Organ system → Organism.
• A tissue is a group of similar cells performing a common function, so it is the level directly above the cell.

Additional Information

• System is in the sequence but several levels too far ahead — organ system comes after organ.
• Proton moves *down* the hierarchy (it is sub-atomic), and gene is a segment of DNA, sitting inside the molecular level rather than above the cell.
• Below the atom the chain continues into subatomic particles; above the organism it extends to population, community, ecosystem and biosphere.
