The Living World NEET 2025 Notes | Class 11 Botany Made Easy

-

🌍 Introduction

Socho ek baar… ek rock aur ek mango tree mein kya difference hai? Rock bhi grow kar sakti hai (crystals), lekin kya woh living hai? 🤔
Yahi confusion clear karta hai pehla chapter “The Living World”. Ye NEET Botany ka base hai aur har saal 1–2 questions yahan se aate hi hain.

🧬 Characteristics of Living Organisms

1. Growth – Living organisms grow in size aur number. Example: Plants grow in size, bacteria divide into two.


2. Reproduction – Ability to produce offspring. (Sexual ya Asexual)


3. Metabolism – Sare chemical reactions jo cell ke andar hoti hain. (Only in living beings!)


4. Response to Stimuli – Light, sound, touch… sabka response dete hain.



👉 NEET Tip: Growth alone ≠ living property. Crystal bhi grow karta hai but living nahi hai.

🔖 Taxonomy aur Nomenclature

Taxonomy = Classification of organisms.

Binomial Nomenclature (Carolus Linnaeus): Har organism ka 2-part name hota hai → Genus + Species.

Example: Mangifera indica = Mango



👉 Rule yaad rakho:

Pehla word (Genus) → Capital letter

Dusra word (Species) → Small letter

Italic ya underline karke likhna hota hai.



---

📘 Systematics ka Role

Systematics = Classification + Nomenclature + Evolutionary relationship.

Har organism ko unique naam deta hai.

Regional confusion avoid hota hai.

NEET exam mein direct questions aate hain.



---

📝 Quick Revision

Living organisms = Metabolism + Consciousness + Cellular organization.

Taxonomy hierarchy = Kingdom → Phylum → Class → Order → Family → Genus → Species.

Binomial nomenclature → Linnaeus.

❓ NEET FAQs

Q1. The Living World se kitne questions aate hain NEET mein?
👉 Har saal 1–2 questions aate hi hain, specially taxonomy aur nomenclature par.

Q2. Sirf NCERT padhna kaafi hai kya?
👉 Haan! NCERT ki lines + thoda practice questions karna zaroori hai.

The Origin of Teacher’s Day Teacher’s Day in India commemorates Dr. Sarvepalli Radhakrishnan, born on September 5, 1888. A philosopher, statesman, and the second President of India (1962–1967), Dr. Radhakrishnan believed education was the cornerstone of progress. When students and admirers suggested celebrating his birthday, he humbly proposed that the day be dedicated to honoring all teachers instead.

🌱 Plant Kingdom – Bryophytes (Mosses & Liverworts) | NEET 2025 Notes

-
Image
Introduction Bryophytes are often called the “Amphibians of the Plant Kingdom” because they require water for reproduction but can survive on land as well. They form a crucial link between algae and pteridophytes. For NEET aspirants, bryophytes are an important NCERT-based topic that often appear in exams with direct questions. --- General Characteristics of Bryophytes Non-vascular plants (no xylem or phloem) Plant body is thalloid (undifferentiated into true root, stem, and leaves) Anchored by rhizoids instead of roots Reproduction occurs through spores Life cycle shows alternation of generations (gametophyte dominant, sporophyte dependent) --- Classification of Bryophytes Bryophytes are divided into three main groups: 1. Liverworts Example: Marchantia Plant body is dorsiventral, thalloid Asexual reproduction: by fragmentation and gemmae Sexual reproduction: male and female sex organs borne on separate structures 2. Mosses Example: Funaria, Polytrichum Gametophyte has two ...
