In this career guide, you’ll learn everything you need to know about biology as a career, from roles and responsibilities to the work environment and roadmap to becoming a Biologist.

Who's a Biologist?

Do you enjoy learning about different living things – how they look, where they live, what they do? Are you curious about how plants and animals interact with other living beings? If so, consider a career in biology!

Biology, as you may know, is the study of living things. As a biologist, you will, essentially, study life. You will learn how an organism comes into existence, its growth, functions and where it lives. Biology is an incredibly vast science that includes the study of plants (botany), animals (zoology) and microorganisms (microbiology). Curious to know more about this career? Click here to find out.

What will you do?

Conducting research.

You will observe how living things exist in their natural habitat and make a note of what you see and find. You will decide on certain areas that you want to observe and take into account different influencing factors.

Example: When studying animal structure, you will take into account their behaviour, nutrition, physiological distribution and also consider how climate affects these conditions.


Studying living organisms.

You will study many aspects of life such as their life, health, diseases they contract, food they consume, environments they thrive in, etc.

Example: If you’re studying a plant, you will make a note of how much sunlight and water it needs, what bacteria it attracts, etc.


Sharing biological findings.

Once you’ve collected information, you will share your findings with the public through research papers, journals, etc. This information becomes beneficial to other researchers like doctors, pharmacists, ecologists, etc.

Example: If you find that certain plants or animals are resistant to a particular disease, this information can be used when looking for cures and prevention.

Cultivating and breeding organisms.

Most biologists build a culture of bacteria, or breed animals they are studying so they can collect data from the start to the end of their life cycle. You will have to create appropriate living conditions and take care of their nutrition during this time.

Example: If you were studying a particular plant, you would grow a bunch of them in a nursery in order to record as much data as possible.

Where will you work?


Most biologists work in a laboratory where they conduct research and examine organisms.


Some biologists are required to work out on the field. This depends on your area of specialisation. For instance, an animal biologist studying animals will have to visit zoos or forests to observe animals in their natural habitat. 

Research Facilities

Biologists working with researchers spend most of their time going through research papers, conducting experiments, and publishing new findings.

How do you get there?

This stream won’t help you make an entry into this field.

STEP 1: Class XI-XII/Junior College

Opt for science in junior college and make sure you choose biology as one of your subjects.

STEP 2: Graduate Degree

Pursue a three-year Bachelor of Science in Biology from colleges like Ruia’s college (Mumbai), Hansraj College (Delhi), Loyola College (Chennai), etc.

STEP 3: Entrance Exams

During your graduation, start preparing for entrance exams like AIIMS, Tata Institute, JNU and other universities for an MSC in Biology or Biotechnology. You will need at least 50% marks in your graduation to apply for these exams.

STEP 4: Postgraduate Degree

Once you pass the entrance exam, choose your area of specialisation and master in that field. You can opt to specialise in marine biology, wildlife biology, human biology and others.

If you wish to become a certified researcher in the area you specialise in, you must pursue a PhD in the field.

STEP 5: Land a Job

Depending on your area of specialisation, you can work in zoos, pharma companies, government agencies and universities. A job will help you get exposure and good experience as to how exactly things work in the field.

What skills would you need?

Analytical and Data Skills

Analytical and Data Skills

You will receive huge amounts of data from your client. This data will have to be analysed effectively so you can find ways that will help your client reach their customers is the best way possible. While it is true that the more data you analyse, the more insights you generate; analytical thinking will help you narrow down your search and find your key actionable items, thus saving you a lot of time and resources.

Technical Skills

Technical Skills

You will be frequently using accounting software and other financial tools as many CAs need to work with technology to analyse data and prepare financial reports. build this skill
Attention to Detail

Attention to Detail

Working with eggs and embryos is a very tedious task. Every little detail matters when you are observing them. If you are good at giving attention to detail, then your job at the laboratory will be made much easier.

Communication Skills

Communication Skills

It’s harder than ever to get people’s attention, what with so much information being thrown at them. But, people cannot resist a good story. Every good marketing campaign has a story to tell their customers and relate to them on an emotional level. Marketers who tell great stories through their marketing campaigns are always in great demand.

How do you make it to the top ranks?

  • promotion-1
  • promotion-2
  • promotion-3
  • promotion-7


As an intern, you would most likely assist a professor or researcher in the field. You may have to document findings, ensure proper care of the organism and perform other tasks assigned to you. This time will be all about learning.

Junior Biologist

As this is an entry-level job, you will take on simple tasks such as conducting research, experiments and tests that would further help senior biologists evaluate their work. You would also prepare reports on the various findings.

Senior Biologist

At this stage, you will work on independent projects or have assignments given to you. You will oversee the planning and working of the task. You will have juniors and interns working under you. Depending on your area of specialisation, you may also have to travel. For example, a senior wildlife biologist may have to travel to different countries to study wildlife in their natural habitat.


Once you’ve established your credibility in the field, you can get government or private grants to work on your own projects on experiments. You can conduct these experiments as a lone wolf or even hire a team to work with you. Depending on your grant and where you work, you would have access to state-of-the-art equipment.

Pursuing your career locally VS abroad

How much would you get paid?

Your exact salary will depend on various factors, such as the company you're working in and the type of role you've undertaken.

What are your career options?

Biological Technician

As a biological technician, you would be involved in testing blood, urine or cell samples to assist in disease diagnosis and treatment. You would also prepare accurate reports and ensure their compliance with the set quality standards of your facility. You work in a laboratory and utilize various equipment like imaging systems to perform your tasks.



Zoologists study a variety of animal species. You would be studying animal behaviour patterns, their characteristics, how they interact with their ecosystems, etc. You would also be involved in research, animal management, and awareness.


Botanists study plants. These include trees, flowering plants, plant-like things such as moss and seaweed, etc. You will study plants along with their growth, structure, evolution, and uses.


Microbiologists study microscopic (invisible to the naked eye) life forms and processes. You will study the growth, interactions and characteristics of microscopic organisms such as bacteria, algae, fungi, and other types of parasites.

Marine Biology

Marine biologists study organisms and ecosystems in the ocean and other saltwater environments. You will study the interactions between marine plants and animals in their own enviroment and their interactions with coastal areas and the atmosphere.

Forensic Biology

Forensic biologists typically work for law enforcement agencies and private forensic science laboratories. You will examine various pieces of biological evidence collected from crime scenes, including human hair and blood. This will help you extract clues and pinpoint culprits.
