Taxonomy — Classification की Science

🔬 Taxonomy क्या है?

यह Science है जो organisms को describe, name और classify करती है — सभी plants, animals और microorganisms को। सीधे शब्दों में: जीवों को systematically group करने की science।

📊 Linnaeus का Classification Hierarchy — 7 Levels

Three KingdomErnst Haeckel1866Plantae, Animalia, Protista"Ecology" शब्द coin किया | Protista = Amoeba, Paramecium, Euglena
Three DomainCarl Woese1990Bacteria, Archaea, EukaryaProkaryotes और Eukaryotes दोनों cover
Five KingdomR.H. Whittaker1969Monera, Protista, Fungi, Plantae, AnimaliaBasis: Cell structure, Nutrition, Organization, Reproduction
Six KingdomCavalier-Smith6 kingdomsLiving organisms को 6 groups में divide किया

👨‍🔬 Carolus Linnaeus — Triple Title

🌐 Three Domain Classification (Carl Woese 1990)

1. Bacteria

True Prokaryotes — most common

2. Archaea

Extreme environments में — hot springs, salt lakes. No peptidoglycan

3. Eukarya

All Eukaryotes: Protists, Fungi, Plants, Animals

3

Kingdom Monera

🦠 Kingdom Monera — Key Features

✅ Eubacteria (True Bacteria)

  • Most common group
  • Cell wall में Peptidoglycan होता है
  • Normal environments में रहते हैं

🌋 Archaebacteria (Ancient Bacteria)

  • Extreme environments: Hot springs, Salt lakes, Swamps
  • Cell wall में Peptidoglycan absent
4

Kingdom Protista

🔭 Kingdom Protista — Key Features

🦠 Phylum Protozoa — Examples

OrganismMovementSpecial Feature
EuglenaFlagellumAutotrophic + Heterotrophic दोनों
AmoebaPseudopodiaFood को engulf करता है
ParameciumCiliaHair-like structures से movement
PlasmodiumMalaria का कारण

Kelp को Phylum Protista में classify किया जाता है।

5

Kingdom Fungi

🍄 Kingdom Fungi — Key Features

🤝 Lichen = Fungi + Algae का Symbiotic Relationship (साथ रहना)
Fungus → Shelter, Protection, Water और Nutrients देता है
Blue-green algae (या Green algae) → Photosynthesis से Fungus को food बनाकर देता है
Lichen = Natural Indicator भी है!

🍄 Types of Fungi (4 Classes)

Chytridiomycota

Aquatic fungi — simplest

Zygomycota

E.g. Bread mold (Rhizopus)

Basidiomycota

E.g. Mushrooms

Ascomycota

E.g. Yeast, Penicillium

Kingdom Plantae — Overview

🌱 Kingdom Plantae — Basic Features

📏 Classification का Basis

🌿 Cryptogamae vs Phanerogamae

FeatureCryptogamae (छुपे reproductive organs)Phanerogamae (दिखते reproductive organs)
Seeds/Fruits/Flowers❌ Absent✅ Present
Reproductive OrgansHidden (छुपे)Exposed (दिखते हैं)
EvolutionLess evolved (कम evolved)Highly evolved (ज्यादा evolved)
ExamplesThallophytes, Bryophytes, PteridophytesGymnosperms, Angiosperms
🧬 Ploidy का जरूरी point:
Thallophyta + Bryophyta → Dominant plant body Haploid (Gametophytic)
Gymnosperms + Angiosperms → Dominant plant body Diploid (Sporophytic)

1. Thallophyta (Algae)

🌊 Thallophyta — Key Features

🎨 Types of Algae — Color के आधार पर

TypeColorFood StorageExamples
🟢 Chlorophyceae Green (हरी) Starch Chlorella (proteins), Spirulina (superfood), Spirogyra, Ulothrix, Ulva, Chara, Volvox, Cladophora
🟤 Phaeophyceae Brown (भूरी) Mannitol + Laminarin Sargassum, Laminaria (Kelp), Ectocarpus, Fucus
🔴 Rhodophyceae Red (लाल) Gelidium, Porphyra, Gracilaria, Polysiphonia

🧠 Green Algae याद करें: SUVCC

SSpirogyra
UUlothrix
VVolvox
CChara
CCladophora

🧠 Brown Algae याद करें: SELF

SSargassum
EEctocarpus
LLaminaria (Kelp)
FFucus
🍮 Algae से बनने वाले Products (Exam Important!):
Agar → Red algae (Gelidium, Gracilaria) → Jelly बनाने में use
Algin (Alginic acid) → Brown algae → Hydrocolloid
Carrageenan → Red algae → Food products में gelling agent
Mannitol → Brown algae (Kelp) → Sweet alcohol
Spirulina → Green algae → Superfood (protein से भरपूर)

2. Bryophyta (Amphibians of Plant Kingdom)

🌿 Bryophyta — Key Features

🌱 Mosses

Examples: Funaria

Damp walls और मिट्टी पर उगते हैं

🍃 Liverworts

Examples: Marchantia, Riccia

Flat, liver-shaped body

🌿 Hornworts

Horn-like sporophyte होता है

Moist habitats में

3. Pteridophyta (First Vascular Plants)

🌿 Pteridophyta — Key Features

4. Gymnosperms (Naked Seeds)

🌲 Gymnosperms — Key Features

5. Angiosperms (Covered Seeds — Flowering Plants)

🌸 Angiosperms — Key Features

🌾 Monocots vs Dicots

Feature🌾 Monocots (एक बीजपत्री)🌹 Dicots (दो बीजपत्री)
Cotyledons1 cotyledon2 cotyledons
RootsFibrous roots (झाड़ीदार)Tap root (मूसला जड़)
Leaf VeinsParallel (समानांतर)Net/Reticulate (जालनुमा)
Vascular BundlesScattered (scattered throughout)Ring में arranged
Flower PartsThrees में (3 या 6)Fours या Fives में (4 या 5)
ExamplesGrass, Lily, Wheat, Rice, Onion, GarlicRose, Sunflower, Tamarind, Mango, Pea, Gram
