Question

Select the wrong statement.

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Diatom characteristics
 **Related Topics**: Phytoplankton, Diatomaceous earth, Marine ecology
 **Prerequisites**: Basic knowledge of cell structure and marine organisms.
## SOLUTION PATHWAY
**Given Information**:
  Four statements about diatoms.
  Need to identify the incorrect statement.
**Method & Steps**:
 1. Analyze each statement individually to determine its accuracy.
  Reasoning: Evaluate each statement against known facts about diatoms.
  Formula/Rule: N/A
 2. Identify the statement that contradicts established knowledge about diatom biology.
  Working: Examining the properties of diatom cell walls, their role in the ecosystem, and the formation of diatomaceous earth.
  Key Point: Diatom cell walls are made of silica, a very strong material.
 3. Select the incorrect statement as the answer.
  Result: Statement B is incorrect.
  Verification: Confirm the accuracy of the other statements using reliable sources on diatoms.
 ## OPTION ANALYSIS
A ✓: Diatoms are indeed microscopic single-celled algae that drift passively in water currents (plankton).
B :x: The walls of diatoms are NOT easily destructible. They are composed of silica (glass), making them remarkably durable. This durability is what allows them to contribute to the formation of diatomaceous earth.
C ✓: Diatomaceous earth is a sedimentary rock formed from the accumulation of fossilized diatom cell walls.
D ✓: Diatoms are significant primary producers in marine and freshwater ecosystems, forming the base of many food webs.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing diatoms with other microscopic organisms: Understanding the unique characteristics of diatom cell walls is crucial.
  2.Overlooking the strength of diatom cell walls:  Remembering the silica composition is key to avoiding this mistake.
 **Quick Tips**:
  1.Remember the silica cell walls for diatoms.
  2.Diatoms are a significant part of the ocean's food web.

D VINOD · Answer

Diatoms are microscopic and float passively in water.

D VINOD · Answer

The correct Option is "The walls of diatoms are easily destructible."

D VINOD · Answer

‘Diatomaceous earth’ is formed by the cell walls of diatoms.

D VINOD · Answer

Diatoms are chief producers in the oceans.
