Family Fabaceae/Leguminosae - Morphology Of Flowering Plants|Class 11 Biology|Chap-5|NEET/CBSE/NCERT

Описание: Welcome back learners! 👋
Aaj ke is lecture mein hum Morphology of Flowering Plants chapter ka ek aur bahut important aur frequently asked topic padhenge —
👉 Plant Family: Leguminosae/Fabaceae 🌿
Leguminosae family NEET + Board exams dono ke liye extremely important hai, kyunki isi family se humein milte hain pulses jaise pea, gram, soybean, groundnut aur kai economically important plants.
Is family se direct NCERT-based questions pooche jaate hain —
👉 Papilionaceous corolla, vexillary aestivation, diadelphous stamens, root nodules with Rhizobium, marginal placentation aur legume fruit.
📌 Is video mein hum detail mein cover karenge:
🔹 Introduction to Leguminosae (NCERT)
– Distribution & general characters
– Why Leguminosae is called Fabaceae / Papilionaceae
– Importance of Leguminosae in human life
🔹 Vegetative Characters
– Habit: Herbs, shrubs, trees & climbers
– Root: Tap root system
– Root nodules with Rhizobium (nitrogen fixation – NCERT point)
– Stem: Erect, branched or climber
– Leaf: Alternate, compound
– Stipulate leaves
– Presence of pulvinus (diagnostic feature)
– Reticulate venation
🔹 Inflorescence
– Usually racemose
– Sometimes solitary axillary
🔹 Flower Characters (Highly Exam Oriented 🌼)
– Flowers bracteate and pedicellate
– Complete, bisexual, zygomorphic
– Pentamerous, hypogynous flower
🔹 Floral Whorls
– Calyx: 5 sepals, gamosepalous, valvate aestivation
– Corolla: 5 petals, papilionaceous
– Standard (vexillum), wings (alae), keel (carina)
– Vexillary aestivation (descending imbricate)
– Androecium: 10 stamens
– Diadelphous (9+1) arrangement
– Gynoecium: Monocarpellary, syncarpous
– Ovary superior, unilocular
– Marginal placentation
🔹 Floral Formula & Floral Diagram
– Pure NCERT-based explanation
– Diagram interpretation for NEET & Board exams
🔹 Fruit & Seed
– Fruit: Legume (pod)
– Dry, dehiscent fruit
– Seeds non-endospermic and protein-rich
🔹 Pollination
– Mostly entomophilous (insect pollination)
🔹 Economic Importance of Leguminosae
– Food crops: Pea, gram, lentil, soybean
– Oil plant: Groundnut
– Fodder plants: Trifolium, Medicago
– Timber: Dalbergia
– Ornamental plants: Lathyrus, Clitoria
🔹 Important NCERT Exam Points
– Root nodules & nitrogen fixation
– Papilionaceous corolla
– Vexillary aestivation
– Diadelphous androecium (9+1)
– Marginal placentation
– Legume fruit
– NEET + Board frequently asked facts
– One-shot revision highlights
