Five Kingdom Classification System — NEET Biology
📚 Practice ConceptIn the previous chapter, we looked at the broad classification of living organisms under the system proposed by Whittaker (1969) wherein he suggested the Five Kingdom classification viz. Monera, Protista, Fungi, Animalia and Plantae. In this chapter, we will deal in detail with further classification within Kingdom Plantae popularly known as the 'plant kingdom'.
Which of the following statements regarding the placement of fungi outside Kingdom Plantae in modern classification are correct? S1. Fungi lack chlorophyll and do not perform photosynthesis under natural conditions. S2. The cell wall of fungi is mainly composed of chitin, whereas plant cell walls are primarily cellulosic. S3. Fungi obtain nutrients by absorption after extracellular digestion of organic matter. S4. Fungi store reserve food material predominantly in the form of starch similar to higher plants. S5. Fungi exhibit a filamentous body organization consisting of hyphae forming a mycelium. S6. All fungi reproduce only by sexual methods involving gamete fusion.
View solution & NCERT explanation
Correct answer: B — S1, S2, S3 and S5 are correct
NCERT classifies fungi separately from plants based on fundamental differences in nutrition, cell wall composition, and body organization. S1 is correct as fungi lack chlorophyll and are non-photosynthetic. S2 is correct because fungal cell walls contain chitin, unlike cellulose in plants. S3 is correct since fungi are heterotrophic and absorb nutrients after extracellular digestion. S5 is correct because the fungal body is typically made of hyphae forming a mycelium. S4 is incorrect as fungi store glycogen, not starch. S6 is incorrect because fungi show both asexual and sexual reproduction. Thus, only the statements listed in option B are correct.
