Select the wrong statement.

  1. Mushrooms belong to basidiomycetes.
  2. Cell wall is present in members of fungi and plantae.
  3. Pseudopodia are locomotory and feeding structures in sporozoans.
  4. Mitochondria are the powerhouse of the cell in all kingdoms except monera.

Answer

(3) Pseudopodia are locomotory and feeding structures in sporozoans.

Solution

As per NCERT, pseudopodia (false feet) are found in amoeboid protozoans (e.g., Amoeba), which use them to capture prey.

Sporozoans (e.g., Plasmodium) have an infectious spore-like stage in their life cycle and possess no locomotory structures.

∴ Statement (3) is wrong.

Mushrooms ( Agaricus) are basidiomycetes; fungi (chitin) and plants (cellulose) have cell walls; monerans are prokaryotes without mitochondria ⇒ (1), (2) and (4) are correct.

Answer: (3)
