Class 12: Core Botany Topics

These chapters are high‑yield and part of the official NEET syllabus for 2026:

Sexual Reproduction in Flowering Plants

• Flower structure & development of male/female gametophytes
• Pollination & agents
• Double fertilisation
• Seed and fruit formation
• Special modes (e.g., apomixis, polyembryony)

Molecular Basis of Inheritance

• DNA/RNA structure & function
• DNA replication
