What are the advantages of classifying organisms?
अपने चारों ओर फैले जीव रूपों की विभिन्नता के तीन उदाहरण दें।
आकार: कुछ जीव जैसे बैक्टीरिया अतिसूक्ष्म होते है तो दूसरी ओर ह्वेल जैसे जीव कई मीटर तक लम्बे होते हैं।
जीवन काल: कुछ जीवों जैसे मच्छर का जीवन काल अति न्यून होता है जबकि कुछ पौधे सैकड़ों साल जिन्दा रहते है।
रंग: कुछ जीव रंगहीन (पारदर्शी तक) होते है तो कुछ विभिन्न आकर्षक रंगों युक्त होते हैं।
How would you choose between two characteristics to be used for developing a hierarchy in classification?
Explain the basis for grouping organisms into five kingdoms.
Number of cells: Unicellular eukaryotes are kept in the kingdom Protista, while multicellular eukaryotes are kept in other kingdoms.
Mode of nutrition and presence of cell wall: Hetereotrophic organisms in which cell wall is present are taken under the kingdom fungi.
Autotrophic organisms in which cell wall is present are taken in the kingdom Plantae. Organisms in which cell wall is absent are taken in the kingdom Animalia.
What are the major divisions in the Plantae? What is the basis for these divisions?
Thallophyta: Simple body design; with no differentiation into root, stem and leaves.
Bryophyta: Body is differentiated into stem and leaf-like structures. Vascular system is absent.
Pteridophyta: Body is differentiated into root, stem and leaves. Vascular system is present.
Reproductive organs are inconspicuous. Seeds are not produced.
Gymnosperms: Seeds are naked.
Angiosperms: Seeds are covered.
