Have a Better Understanding of Botany & Zoology

Biology is a broad field to study. Before we take you to the study essentials, we would like you to go through the basic information about the two crucial parts of NEET Biology.



1. Zoology

Zoology or Animal Biology is a very interesting yet complex subject of the NEET Biology Syllabus. The branch responsible for the study of Animal Kingdom includes architecture, embryology, evolution, classification, practices, and the distribution of both animals – living and extinct. Through Zoology, you can learn about how animals interact with the natural system.

Zoology is also about animal interactions with the ecosystem. It is a very interesting stream of Biology and works on the study of the Animal Kingdom and its structures, evolution, embryos, practices, classification, and distribution of living and extinct animals. Students are advised to focus on topics such as Reproduction and Psychology while preparing for the exam.

Zoology mainly contains 45 questions in the test and among those, most are easy and limited to try. Considering the level of difficulty of animal questions, experts say that in the entrance test, about 35% of the questions have a high level of difficulty and 15% of questions have a simple level. Zoology comprises important topics like –

  • Animal Diversity
  • Human Physiology
  • Animal Tissue
  • Human Reproduction
  • Cockroach
  • Evolution
  • Animal Husbandry
  • Human Health & Disease
2. Botany

Botany or Plant Biology, also known as Plant Science or Phytology is a crucial part of NEET Biology & Science of Plant Life. A person who specialized in the field of plant study is known as Botanist or Plant Scientist. Botany also includes the Study of Fungi & Algae.

Modern Botany deals with plant structure, growth, differentiation, reproduction, biochemistry & primary metabolism development, disease & plant taxonomy.

Botany mainly consists of 50% of questions of average difficulty level; 35% of questions are mainly of high difficulty level and 15% of questions are of an easy level. On the other hand, topics like Genetics & Biotechnology carry high weight followed by Ecology in the exam.

Some of the important topics of Botany are given below –

  • Plant Anatomy
  • Plant Morphology
  • Cell Biology & Cell Division
  • Biomolecule
  • Plant Physiology
  • Plant Reproduction
  • Genetics & Biotechnology
  • Biology in Human Welfare
  • Ecology
  • Plant Diversity

The preparation for the biology subject is not sufficient to appear for the National Eligibility cum Entrance Examination, students must prepare the physics and chemistry subjects also. The process of preparation of notes, important formula and mock tests are provided in the links given below.
