Pick the wrong statement

The correct option is "Walls of diatoms are destructible easily".

To understand why this statement is incorrect, let us look at the structure and composition of diatoms:
1. Composition of the cell wall: Diatoms possess unique, double-shelled cell walls (known as frustules) composed of silica (silicon dioxide).
2. Indestructibility: Because their cell walls are embedded with silica, they are extremely tough, highly resistant to decay, and are indestructible under normal environmental conditions.
3. Formation of Diatomaceous Earth: When diatoms die, their indestructible siliceous cell walls accumulate at the bottom of water bodies. Over millions of years, this accumulation forms a crumbly, silica-rich sedimentary deposit known as diatomaceous earth.
4. Habits and Abundance: Diatoms are microscopic protists that float passively in water currents (plankton). They are also the chief primary producers in the oceans.

Since the cell walls of diatoms are actually highly resistant and indestructible rather than easily destructible, the statement "Walls of diatoms are destructible easily" is false, making it the correct choice for this question.
