For class 12 students, biology is one of the important subject and specially for scoring in exam. There are 16 chapters of biology included in class 12 syllabus. Most important diagrams from previous year question papers and the most asked diagrams are included. There are 13 diagrammatic illustrations are included. Students can prefer these diagrams before going to exam.

Chapter 2 : Sexual reproduction in flowering plants

These are the diagrams are drawn in this chapter.
