Hey, hope you are doing well!

I went through the website and due to some technical issue the syllabus link is not working. But I am still adding the link here, please check it time to time if it opens.

MCC syllabus (https://www.mcc.edu.in/images/IQAC/NAAC/Criteria1/M.Sc._Plant_Biology__Plant_Biotechnology.pdf)

Plant biology and botany are same. Both of these are studies on plants. Plant biology and botany focuses on the total plant kingdom.

But plant biotechnology consists of introduction of desirable traits into plants through genetic modification. So plant biotechnology is different from plant biology or botany.

And yes its definitely a good option after BSc in Zoology. But only if you are actually interested in the subjects and the study area.

Always pursue a course only if you fully are interested in it.

All the best!
