Question

Select the wrong statement :

• A. Cell wall is present in members of Fungi and Plantae.
• B. Pseudopodia are locomotory and feeding structures in Sporozoans.
• C. Mushrooms belong to Basidiomycetes.
• D. Mitochondria are the powerhouse of the cell in all kingdoms except Monera.

Answer 1

The Correct Option is B

To determine the wrong statement among the given options, we need to evaluate each statement based on known biological facts:

1. Cell wall is present in members of Fungi and Plantae.

   This statement is true. The cell wall is indeed a characteristic feature of both Fungi and Plantae. In plants, it is composed mainly of cellulose, whereas in fungi, it is composed of chitin.

2. Pseudopodia are locomotory and feeding structures in Sporozoans.

   This statement is incorrect. Pseudopodia are extensions of the cell membrane used for locomotion and feeding, observed in organisms like Amoeba, which belong to the group Sarcodina (Amoebozoa), not Sporozoans. Sporozoans, like Plasmodium, possess different structures for movement and feeding, as they are generally parasitic in nature.

3. Mushrooms belong to Basidiomycetes.

   This statement is true. Mushrooms are a type of fungi and are classified under the Basidiomycetes class. This group is characterized by the production of basidiospores.

4. Mitochondria are the powerhouse of the cell in all kingdoms except Monera.

   This statement is accurate. Mitochondria are known as the powerhouse of the cell because they generate ATP, the energy currency of the cell. Monera, primarily comprising bacteria, do not have mitochondria since they are prokaryotic organisms and lack membrane-bound organelles.

Based on these evaluations, the incorrect statement is: Pseudopodia are locomotory and feeding structures in Sporozoans.
