Botany is a subject that mainly deals with the science of plant, their life structure and many more things. The Botany course, in particular, has several branches, such as plant ecology, plant pathology, forensic Botany, palaeobotany and archaeobotanical these all subjects are included in 3 years Bachelor of Science program on botany. You need to mention clearly of which university you need the syllabus for 1st year botany honours. I would rather suggest you to go through the link attached here to get an idea about the syllabus of 1st year. Actually this is the syllabus of an University and for all of the university the syllabus is almost similar. https://drive.google.com/file/d/1Q0OvBwHZeTzjJSA1YVtTshooPY6lGdtJ/view?usp=drivesdk
