About Biologist

Biology deals with the study of life and is a branch of natural sciences. It deals with living organisms and their interactions with the environment. Over the years, Biology has become one of the standard subjects of instruction in schools. All the higher learning institutes across the world offer courses in Biology. A popular career option in the field is that of a biologist who plays a vital role in examining the structure, origin, growth, function and distribution of living things. A biologist will also classify and describe organisms, their functions and the way these species come into existence. Biology has emerged as one of the dominating fields in modern science in the recent years. Therefore, a career in biology is a great choice for students.

Eligibility to become Biologist

Usually, higher-level jobs in Biology require higher-level educational qualifications. If you want to make a career in Biology, you should start from Class 12 itself. After Class 12, students can take up courses in associated fields of Biology like Zoology, Botany, Aquatic Biology, Biotechnology, Fishery Science, Marine Biology etc at Bachelor’s level. After the Bachelor’s degree level, students can take up Master’s followed by research courses in Biology. Students with at least a Master’s degree in Biology or associated fields will have chances to get better jobs.

Subjects Combination: For taking up Bachelor’s course in Biology, students must choose Science stream in Class 12 with Biology as one of the major subjects of study.


  • Class 12 with Science stream (Biology as major subjects) is mandatory to take up Bachelor’s course in Biology and associated courses.
  • For taking up Master’s course in Biology and associated fields, students must have a Bachelor’s degree in the same field.
  • For taking up M.Phil and Ph.D. courses in Biology, Masters Degree in Biology and associated fields are mandatory.
  • For most UG courses, there will no entrance test except for Biomedical Engineering course.
  • For all master’s courses in biology, students will have to clear the entrance test conducted by universities/ institutes.
  • There will be also an entrance test for Ph.D. and M.Phil courses.

Types of Job Roles Biologist

Biologists are required for diverse jobs. The following are some of the job profiles that Biologists can take up after obtaining the necessary skills.
