2. Most Important Definitions Table

Term	Meaning	NEET Keyword
Biodiversity	Number and types of organisms on earth	1.7–1.8 million species
Systematics	Study of diversity + relationship among organisms	Evolution included
Taxonomy	Identification + Nomenclature + Classification	Main branch
Identification	Recognition of organism	Essential characters
Nomenclature	Scientific naming	Universal name
Classification	Arrangement into groups	Similar characters

---

3. Mnemonic for TAXONOMY

Taxonomy = I.N.C

👉 I N C

I = Identification
N = Nomenclature
C = Classification

याद रखें:

"I Need Classification"

(I → Identification, N → Nomenclature, C → Classification)

---

4. Systematics vs Taxonomy

Systematics	Taxonomy
Broader concept	Narrow concept
Includes evolution	Doesn't focus on evolution
Diversity + relationship	Identification, naming, classification
Developed from Systema Naturae	Part of systematics

Mnemonic

Systematics = T + E

Taxonomy + Evolution

---

5. Characterization Table

Organism को पहचानने के लिए किन चीजों का अध्ययन किया जाता है?

Branch	Study
Morphology	External structure
Anatomy	Internal structure
Cytology	Cell structure
Embryology	Development
Ecology	Environment relationship

---

Easy Mnemonic

MACE

M → Morphology
A → Anatomy
C → Cytology
E → Embryology
+ Ecology

Sentence:

👉 "My Aunt Cooks Excellent"

---

6. Scientific Names

Purpose

✔ One organism = One name

✔ Same name all over world

✔ Universal communication

---

International Codes

Code	Full Form	Organism
ICBN	International Code for Botanical Nomenclature	Plants
ICZN	International Code for Zoological Nomenclature	Animals

---

Mnemonic

BZ Rule

B = Botanical = Plants
Z = Zoological = Animals

---

7. Binomial Nomenclature

Proposed by:

Carolus Linnaeus

---

Bi = Two Names

Genus + Species

Example:

Mangifera indica

Part	Meaning
Mangifera	Genus
indica	Species

---

Mnemonic

G-S Formula

Genus → Start Capital
Species → Start Small

Example:

Mangifera indica

M = Capital

i = small

---

8. Universal Rules of Nomenclature

Rule	Example
Latinized	Homo sapiens
Italics when printed	Homo sapiens
Underlined separately when handwritten	Homo sapiens
Author name abbreviated	Mangifera indica Linn.

---

Mnemonic

L.I.U.A

L = Latinized
I = Italics
U = Underline
A = Author name

Sentence:

👉 "Little Intelligent Uncle Aman"

---

9. Advantages of Binomial Nomenclature

Advantage	Explanation
Universal	Same worldwide
Definite	No confusion
Easy naming	New species can be named easily

---

Mnemonic

UDE

U = Universal
D = Definite
E = Easy naming

Sentence:

👉 "Use Data Easily"

---
