admin@boarding-school.in

Class 11 Salient features and classification of Monera, Protista and Fungi- Monera, Protista, and Fungi are three distinct biological kingdoms, each with its own characteristics and classifications. Here’s an overview of the salient features and classifications for each:

  1. Monera:
    • Cell Type: Unicellular (mostly), prokaryotic cells (lack membrane-bound organelles and a true nucleus).
    • Cell Wall: Present, composed of peptidoglycan.
    • Mode of Nutrition: Autotrophic or heterotrophic.
    • Reproduction: Asexual (binary fission) and sexual (conjugation).
    • Examples: Bacteria (e.g., Escherichia coli), Archaea.
    Classification:
    • Divided into two major groups: Bacteria and Archaea.
    • Bacteria are further classified based on shape (cocci, bacilli, spirilla) and staining characteristics (Gram-positive, Gram-negative).
  2. Protista:
    • Cell Type: Mostly unicellular, eukaryotic cells (contain membrane-bound organelles and a true nucleus).
    • Cell Wall: Present in some, composed of various materials (cellulose, silica, etc.).
    • Mode of Nutrition: Autotrophic, heterotrophic, or mixotrophic.
    • Reproduction: Asexual (binary fission, multiple fission) and sexual (conjugation, syngamy).
    • Examples: Algae (e.g., Euglena), Protozoa (e.g., Amoeba, Paramecium).
    Classification:
    • Divided into three main groups: Animal-like protists (protozoans), Plant-like protists (algae), and Fungus-like protists.
    • Further classification is based on characteristics such as locomotion, cell structure, and mode of nutrition.
  3. Fungi:
    • Cell Type: Mostly multicellular, eukaryotic cells.
    • Cell Wall: Present, composed of chitin.
    • Mode of Nutrition: Heterotrophic, absorb nutrients from the surroundings (saprophytic or parasitic).
    • Reproduction: Asexual (spore formation) and sexual (formation of specialized structures like gametangia).
    • Examples: Mushrooms, yeasts, molds.
    Classification:
    • Divided into several phyla, including Zygomycota, Ascomycota, Basidiomycota, and Chytridiomycota.
    • Classification is based on reproductive structures, spore formation, and life cycle characteristics.

These three kingdoms represent diverse groups of organisms with distinct features and ecological roles in the biological world. Monera includes bacteria and archaea, Protista encompasses a variety of unicellular eukaryotes, and Fungi comprises various fungi with unique modes of nutrition and reproduction.
