The Botany syllabus for UPSC Mains is designed for candidates who have a strong foundation in plant sciences and wish to opt for this subject as their optional. It covers a broad range of topics, from the fundamental concepts of plant anatomy and physiology to more advanced areas such as genetics, biotechnology, and ecology. The syllabus is structured to test both theoretical knowledge and practical application, ensuring that candidates can demonstrate a deep understanding of the subject matter in relation to the demands of the Civil Services Examination.
UPSC Botany Optional Syllabus
The Botany optional in UPSC consists of two papersâPaper I and Paper IIâeach carrying 250 marks. These papers are structured to evaluate the candidateâs grasp of botanical concepts and their analytical skills. Paper I is divided into two sections, each containing four questions. Candidates must answer Question 1 from Section 1 and Question 5 from Section 2, as these are compulsory. For the remaining six questions, candidates can strategically choose those where they feel most confident, allowing them to maximize their score by selecting the questions they can answer best.
