🌿 Introduction to Morphology of Flowering Plants
Morphology refers to the study of external structure and form of organisms. In botany, morphology deals with the study of structure, form, and visible characteristics of plants.
The chapter Morphology of Flowering Plants is one of the most important chapters in Class 11 Biology because:
It builds the foundation of plant science.
It helps in identification of plant families.
It is frequently asked in NEET and board exams.
It improves diagram-based understanding.
Flowering plants (Angiosperms) are the most advanced and dominant group of plants. They consist of two main groups:
Monocotyledons
Dicotyledons
The morphology of flowering plants includes the study of:
Root
Stem
Leaf
Inflorescence
Flower
Fruit
Seed
Let us study each in detail.
🌱 1. The Root
1.1 Definition
The root is the underground part of the plant that develops from the radicle of the embryo.
1.2 Functions of Root
Absorption of water and minerals
Anchorage (fixes plant to soil)
Storage of food
Synthesis of plant growth regulators
Mechanical support
1.3 Types of Root Systems
A. Tap Root System
Develops from radicle
Primary root persists
Seen in dicots
Example: Mustard, Pea
Characteristics:
Has primary root
Secondary and tertiary branches
B. Fibrous Root System
Primary root is short-lived
Replaced by cluster of roots
Seen in monocots
Example: Wheat, Rice
Characteristics:
No main root
Roots arise from stem base
C. Adventitious Root System
Develop from parts other than radicle
Example: Banyan, Maize
1.4 Modifications of Roots
For Storage
Carrot (conical)
Radish (fusiform)
Turnip (napiform)
For Support
Prop roots (Banyan)
Stilt roots (Maize)
For Respiration
Pneumatophores (Mangrove plants)
🌿 2. The Stem
2.1 Definition
The stem develops from plumule and is generally the ascending part of the plant.
2.2 Functions
Support leaves and flowers
Conduct water and nutrients
Photosynthesis (in green stems)
Storage
Vegetative propagation
2.3 Stem Modifications
A. Underground
Rhizome (Ginger)
Tuber (Potato)
Bulb (Onion)
Corm (Colocasia)
B. Sub-aerial
Runner (Strawberry)
Stolon
Offset
Sucker
C. Aerial
Tendrils (Cucurbita)
Thorns (Citrus)
Phylloclade (Opuntia)
🍃 3. The Leaf
3.1 Definition
Leaf is a lateral, flattened structure borne on stem, mainly concerned with photosynthesis.
3.2 Parts of Leaf
Leaf base
Petiole
Lamina
3.3 Venation
Reticulate Venation
Veins form network
Seen in dicots
Parallel Venation
Veins parallel
Seen in monocots
3.4 Types of Leaves
Simple leaf
Compound leaf
Pinnately compound
Palmately compound
3.5 Leaf Modifications
Tendrils (Pea)
Spines (Cactus)
Storage leaves (Onion)
Insectivorous leaves (Pitcher plant)
🌼 4. Inflorescence
Inflorescence refers to the arrangement of flowers on floral axis.
Types
1. Racemose
Main axis continues to grow
Flowers arranged in acropetal order
2. Cymose
Main axis terminates in flower
Flowers arranged in basipetal order
🌸 5. The Flower
Flower is the reproductive structure of angiosperms.
5.1 Parts of Flower
Four Whorls
Calyx
Corolla
Androecium
Gynoecium
5.2 Types of Flowers
Complete / Incomplete
Bisexual / Unisexual
Actinomorphic / Zygomorphic
Hypogynous / Perigynous / Epigynous
🍎 6. The Fruit
Fruit develops from ovary after fertilization.
Parts
Pericarp (Epicarp, Mesocarp, Endocarp)
Seed
Types of Fruits
Simple
Aggregate
Multiple
True Fruit
Develops from ovary only
False Fruit
Other floral parts also involved (Apple)
🌰 7. The Seed
Seed is the fertilized ovule.
Structure
Seed coat
Embryo
Cotyledon
Types
Dicot Seed
Two cotyledons
Example: Bean
Monocot Seed
One cotyledon
Example: Maize
📚 Differences Between Monocot and Dicot
Feature
