Taxonomic Hierarchy: Kingdom to Division — NEET Biology
📚 Practice ConceptIn this chapter we will study characteristics of Kingdoms Monera, Protista, Fungi and Plantae. The next higher category called Phylum (in case of animals) or Division (in case of plants) groups together all the classes which have common characteristics. Kingdom Plantae and Animalia, commonly referred to as plant and animal kingdoms respectively, will be dealt separately in chapters 3 and 4.
Consider the following statements : 1. Nostoc belongs to Kingdom Monera, subdivision Cyanobacteria, is prokaryotic, photosynthetic, and fixes nitrogen in heterocysts. 2. Paramecium belongs to Kingdom Animalia, phylum Protozoa, shows holozoic nutrition and locomotion by cilia. 3. Agaricus (mushroom) belongs to Kingdom Fungi, class Basidiomycetes, with septate mycelium and reproduces by basidiospores. 4. Cholrella belongs to Kingdom Plantae, division Algae, is filamentous, photosynthetic, and eukaryotic. 5. Hydra belongs to Kingdom Protista, class Cnidaria, and shows alternation of generations. How many of the above statements are correct?
View solution & NCERT explanation
Correct answer: A — 1 and 3 only
Statement 1 (Correct): Nostoc is a cyanobacterium → Kingdom Monera, prokaryotic, photosynthetic, fixes nitrogen in heterocysts. Statement 2 (Incorrect): Paramecium is a ciliate protozoan but belongs to Kingdom Protista, not Animalia. Statement 3 (Correct): Agaricus (mushroom) → Kingdom Fungi, class Basidiomycetes, septate mycelium, sexual spores = basidiospores. Statement 4 (Incorrect): Chlorella is a green alga but placed under Protista in 5-kingdom classification, not Plantae. Statement 5 (Incorrect): Hydra is a cnidarian → Kingdom Animalia, not Protista. Alternation of generations is absent in Hydra (cnidarians show polyp–medusa alternation, not plant-like alternation of generations). Thus, only Statements 1 and 3 are correct.
