Morphology of flowering plants
Introduction:
You might have read notes on morphology. This ncert based note will change your mind strategy and give you strength of content with concept. Go through entire article and believe me that you will get through self-study idea for the chapter. This article gives you ncert based strategy for better scoring in NEET.
1. Root System
Types:
Tap Root: Dicots (e.g., Mustard)
Fibrous Root: Monocots (e.g., Wheat)
Adventitious Root: Banyan (prop roots), Maize (stilt roots)
Functions: Absorption, anchorage, storage
2. Stem
Aerial, ascending part with nodes/internodes
Modifications:
Rhizome (Ginger), Tuber (Potato), Runner (Grass)
3. Leaf
Parts: Leaf base, petiole, lamina
Phyllotaxy:
Alternate (Mustard), Opposite (Guava), Whorled (Alstonia)
Types of Venation:
Reticulate (Dicot), Parallel (Monocot)
4. Inflorescence
Types:
Racemose: Indefinite growth (e.g., Mustard)
Cymose: Definite growth (e.g., Jasmine) 5. Flower Parts (Floral Formula)
Whorls: Calyx, Corolla, Androecium, Gynoecium
Use floral formula of Solanaceae, Fabaceae, and Liliaceae
6. Fruit
True Fruit: From ovary
False Fruit: From parts other than ovary (e.g., Apple)
7. Seed
Dicot: Two cotyledons, e.g., Gram
Monocot: One cotyledon, e.g., Maize
Endosperm present in monocots
Important Diagrams to Practice:
Types of root systems
Floral diagram of Fabaceae
Phyllotaxy types Mnemonic for Floral Formula (Fabaceae):
K(5) C1+2+(2) A(9)+1 G1 (Keerthi Comes Around Girish – Just to remember order: K, C, A, G*)
