CBSE Class 12 Biology Chapter 1 | Pollen Grain & Anther Structure | CUET/NEET Preparation

Hello Class! Welcome to CUET/Class 12 Biology Series. In this video (Lecture 01), we are starting the first chapter: "Sexual Reproduction in Flowering Plants". We will cover the updated syllabus, introduction to Angiosperms, and the detailed structure of the Male Reproductive System (Stamen). 📝 Topics Covered in This Lecture: New Syllabus Update: Chapters removed from CUET/Class 12 Biology. Introduction: Why Angiosperms are unique? Development of Flower: From Primordium to Bud. Morphology: Calyx, Corolla, Androecium, Gynoecium. Structure of Stamen: Filament and Anther (Dithecous & Bilobed). Anatomy of Anther Wall: Epidermis, Endothecium, Middle Layers, Tapetum. Microsporogenesis: Formation of Microspores from PMC. Structure of Pollen Grain: Exine (Sporopollenin), Intine, and Germ Pores. ⏳ Timestamps: 00:00 - Introduction & Syllabus Update (Excluded Chapters) 03:52 - Modes of Reproduction in Plants 07:09 - Development of Flower (Primordium) 18:08 - Morphology of Flower (Sepals, Petals, Stamen, Carpel) 25:47 - Structure of Stamen & Anther 34:34 - 4 Layers of Anther Wall (Detailed Anatomy) 53:10 - Functions of Tapetum & Ubisch Bodies 1:00:50 - Microsporogenesis (Pollen Formation) 1:14:13 - Structure of Pollen Grain (Exine vs Intine) 📚 Key Concepts: What is the function of Tapetum?
