🌿 Anatomy of Flowering Plants – NEET 2025 Complete Notes (With Updated Syllabus)
🔑 Target Keywords:
Anatomy of flowering plants, notes on tissue systems in plants, dicot and monocot stem differences, and meristematic tissue
🌱 Introduction – Let’s Start with the Basics!
Hello NEET Aspirants 👋
Today, we’re diving into an important yet easy-scoring Class 11 NCERT chapter — Anatomy of Flowering Plants.
As the teacher said in class:
“If you’re starting from zero and want to finish this chapter in one hour — just stay focused!”
So, let’s do exactly that 🌿
Before we begin, note that after the 2025 NCERT update, some topics have been removed.
❌ Deleted Topics (as per latest NCERT):
-
🚫 Secondary Growth
-
🚫 Detailed study of Parenchyma, Collenchyma, and Sclerenchyma
Now, only two major sections remain 👇
-
Tissue System
-
Transverse Sections (T.S.) – Dicot & Monocot
📘 1. What Is Anatomy?
Anatomy means the study of internal structure — how tissues are arranged inside the plant.
As the teacher explained:
“In anatomy, we look inside the plant to see which tissue is where and what function it performs.”
🌿 2. What Is a Tissue?
Definition:
“A group of cells having a common origin and performing a similar function.”
👉 Examples:
-
Epidermal tissue (plant skin) → Protection
-
Xylem & Phloem → Transport
🧩 3. Types of Plant Tissues
| Type | Description | Example |
|---|---|---|
| Meristematic Tissue | Cells that actively divide | Apical meristem, Intercalary meristem |
| Permanent Tissue | Specialised, non-dividing cells | Parenchyma, Collenchyma |
🌱 4. Meristematic Tissue – The Dividing Cells
The teacher said:
“Meristematic tissues are where the plant actually grows — they’re the active regions of growth.”
✨ Definition:
A group of actively dividing cells that contribute to plant growth.
Features:
-
Small, densely packed cells
-
Large nucleus, dense cytoplasm
-
No vacuoles
-
Thin primary cell wall
-
No intercellular spaces
-
High nucleocytoplasmic ratio
📍 5. Classification of Meristems
🔹 Based on Location:
-
Apical Meristem:
Found at root and shoot tips → for primary (length) growth -
Lateral Meristem:
Found along sides (e.g., Vascular Cambium, Cork Cambium) → for secondary (width) growth -
Intercalary Meristem:
Found at nodes/base of leaves (grasses, bamboo) → for regrowth after grazing
💡 Trick: A–L–I → Apical, Lateral, Intercalary
🔹 Based on Origin:
-
Primary Meristem: Directly from the embryo (e.g., Apical meristem)
-
Secondary Meristem: Arises from permanent tissue (e.g., Cork cambium, Vascular cambium)
🍃 6. Permanent Tissues (Overview)
(Deleted but useful for revision 👇)
| Type | Description | Example |
|---|---|---|
| Parenchyma | Living, thin-walled, stores food | Cortex |
| Collenchyma | Living, mechanical support | Petiole, midrib |
| Sclerenchyma | Dead, thick-walled, provides strength | Husk of coconut |
🌾 7. Tissue Systems (As per NCERT)
| Tissue System Function Example | le | |
|---|---|---|
| Epidermal | Protection & exchange | Cuticle, Stomata |
| Ground | Support & storage | Cortex, Pith |
| Vascular | Transport | Xylem, Phloem |
🌿 8. Transverse Sections (T.S.) of Dicot & Monocot Plants
🌱 (A) Dicot Stem (e.g., Sunflower)
-
Epidermis → with cuticle
-
Cortex → Parenchyma & Collenchyma
-
Endodermis → Casparian strips
-
Pericycle → Support
-
Vascular bundles → In a ring
-
Pith → Center
Nature: Collateral, open, endarch
🌾 (B) Monocot Stem (e.g., Maize)
-
Vascular bundles scattered
-
No distinct cortex/pith
-
Bundles → Collateral, closed, endarch
-
Bulliform cells present
🌿 (C) Dicot Root (e.g., Bean)
-
Cortex → Parenchyma layers
-
Endodermis → Casparian strips
-
Xylem → Radial arrangement
-
Vascular cambium → Present (secondary growth possible)
🌾 (D) Monocot Root (e.g., Maize)
-
Polyarch xylem (many arms)
-
No secondary growth
-
Central pith present
🍃 (E) Dicot Leaf (e.g., Sunflower)
-
Upper & lower epidermis with stomata
-
Palisade & spongy mesophyll
-
Reticulate venation
🌾 (F) Monocot Leaf (e.g., Maize)
-
Parallel venation
-
Bulliform cells → Help in leaf folding during water loss
🧠 9. Quick Revision Chart
| Part | Dicot | Monocot |
|---|---|---|
| Stem | Vascular ring | Scattered bundles |
| Root | Tetrarch xylem | Polyarch xylem |
| Leaf | Reticulate venation | Parallel venation |
💡 Trick:
“Ring–Four–Reticulate” = Dicot
“Scattered–Many–Parallel” = Monocot
🧩 10. NEET PYQs (2019–2024)
| Year | Question | Answer |
|---|---|---|
| 2020 | Which meristem helps in the increase of girth? | Lateral meristem |
| 2021 | Bulliform cells are present in? | Monocot leaf |
| 2022 | Casparian strips found in? | Endodermis |
| 2023 | Xylem in a dicot stem is? | Endarch |
