Botany is the optional subject in UPSC, BPSC, MPPSC, UPPSC and others State PCs Exams, which are divide into two papers Paper 1 and Paper 2. This is scoring subject in UPSC and State PCS exams From answer writing point of view.

Botany is the Science subject so here you need only Scientific terms as botanical name, Classification, Taxonomical Character, Plant Physiological, Genetics, Biotechnology, Biochemistry and ecological Terms during of answer writing.

In science subjects if answers describe with Scientific Terms, Figure and Graphical Diagram Students can score good marks in her/him exam which are not only in UPSC or PCS also in College Exam or Others Competitive Exams.
