Biology Chapters for RRB Group D: Preparing for the RRB Group D Exam means you’ll need to be comfortable with a broad set of topics – especially within the General Science section, where biology (life sciences) plays a key role. According to the official syllabus, the General Science part is based on class 10 level Physics, Chemistry and Life Science.
In this article, we’ll walk you through the must-know biology chapters for RRB Group D, how they’re grouped, how to prioritise them and build a smart revision strategy.
Why Biology Matters for RRB Group D?
Before diving into chapter lists, it’s helpful to understand why biology deserves focused attention:
- Within the General Science section in the RRB Group D Exam Pattern of 25 marks, Biology (Life Sciences) often carries a significant portion (approximately 40-50 %) of the questions.
- Questions are asked at a basic level (class 10) but with direct relevance to everyday phenomena (diseases, environment, human body) – making them easier to score with good preparation.
- Biology topics overlap with current affairs (health, environment, ecology) which may help improve accuracy in the section if you stay updated.
Important Biology Chapters for RRB Group D Exam
Given below is a table that divides the chapters you should focus on into 3 broad areas: Botany (plants), Human Biology & Ecology/Environment.
| Chapter Group | Important Topics | Why its Important |
| Botany (Plant Biology) | Classification of Plant Kingdom; Plant Morphology; Plant Tissues; Photosynthesis; Plant Hormones; Plant Diseases; Plant Ecology & Pollution. | These are common MCQ topics; many previous papers ask simple facts. |
| Human Biology / Zoology | Classification of Animal Kingdom; Animal Tissues; Human Blood, Organs & Organ Systems; Human Diseases; Nutrients and Nutrition. | Questions on human body systems and diseases recur in exams; good for straightforward marks. |
| Genetics & Evolution + Ecology/Environment | Cytology (cell structure); Genetics & Heredity; Organic Evolution; Ecology & Environment; Pollution; Natural Resources. | Though slightly conceptual, the exam keeps it basic; awareness of environmental terms adds value for current affairs too. |
Chapter-Wise Checklist for Biology Chapters for RRB Group D
The list given below is a detailed checklist you can use to track your preparation:
Botany:
- Classification of Plant Kingdom
- Plant Morphology (roots, stems, leaves, flowers)
- Plant Tissues (meristematic vs permanent)
- Photosynthesis & Plant Nutrition
- Plant Hormones & Growth Regulators
- Plant Diseases (common ones, pathogens)
- Ecology in Plant Context & Pollution Effects
Human Biology / Zoology:
- Classification of Animal Kingdom
- Animal Tissues
- Human Blood & Circulatory System
- Human Digestive, Respiratory, Excretory Systems
- Human Diseases (viral, bacterial, lifestyle) & Nutrients/Nutrition
- Organ Systems: Heart, Kidney, Brain – basics of structure & function
Genetics, Evolution & Environment
- Cell Structure & Cytology (cell organelles, cell division)
- Genetics & Heredity (basic terms: genes, chromosomes, inheritance)
- Organic Evolution (basic evolutionary terms, adaptation)
- Ecology & Environment (ecosystem, food chain/web, human impact)
- Pollution & Natural Resources (types of pollution, conservation)
Smart Preparation Tips for These Biology Chapters
Given below are some practical tips to ensure your biology preparation is efficient:
- Use class 10 NCERT/Board level textbooks as the syllabus uses basic level concepts.
- Create flash cards for key terms (e.g., hormones, blood groups, plant diseases) — very handy for quick revision.
- Practice MCQs chapter-wise after reading; it helps reinforce memory.
- Relate biology topics to current affairs: e.g., environment/pollution topics, disease outbreaks – these often help increase recall.
- Maintain a revision schedule: Plan 2-3 chapters per study session and revisit completed chapters every week to avoid forgetting.
- Attempt previous years’ RRB Group D question papers for the biology part — it helps you identify recurring topic types.
Prioritisation Strategy
Since time is often limited, prioritise like this:
- High priority (Day 1–7): Human Biology chapters (blood, organ systems, diseases) — straightforward and high frequency.
- Medium priority (Day 8–14): Botany chapters (plant morphology, tissues, photosynthesis) — factual, moderate frequency.
- Lower priority (Day 15–20): Genetics & Ecology/Environment — though important, they are slightly less frequent; but if you already have some background, give them solid time.
Also, if you spot weak areas (say, you struggle with plant hormone concepts or ecology), allocate more time there rather than evenly spreading across all topics.
Summary
Check out the important points summarized below for a quick overview:
- Biology (Life Sciences) is a major chunk of the General Science section in RRB Group D (approx. 40-50 % of that section).
- Focus your preparation on three main groups: Botany, Human Biology/Zoology, Genetics & Environment.
- Use a checklist of chapters like Plant Morphology, Human Organ Systems, Photosynthesis, Evolution, Ecology.
- Use class-10 level textbooks, make flashcards, practice MCQs and link topics with current affairs where possible.
- Prioritise your study: human biology first (highest payoff), then botany, then genetics/ecology.
- Regular revision and solving previous papers are key to making biology a high-scoring section.
Championships are often won in the basics, and the same applies to the “Biology Chapters for RRB Group D”. While biology in this exam is not ultra-advanced, it is a scoring segment – if you prepare it smartly. By systematically covering the grouped chapters, practising MCQs, and revising consistently, you can turn biology into your strength rather than a foregone sacrifice. Align your preparation schedule with the prioritisation strategy, keep an eye on your weak spots, and above all, stay disciplined. With the right approach, you’ll be in a strong position to confidently answer the life-science questions on exam day.
FAQs
In the General Science section of 25 marks, around 10–12 questions are usually from Biology. The exact number varies slightly every year, but Life Science topics consistently hold a significant weightage in the exam.
Some of the most important Biology chapters for RRB Group D include:
Human Body and Organ Systems
Nutrition and Digestion
Diseases and Immunity
Cell Structure and Functions
Photosynthesis and Plant Nutrition
Ecology and Environment
These chapters frequently appear in previous years’ question papers.
Yes. Class 9th and 10th NCERT Science books are more than sufficient for Biology preparation. The RRB Group D Biology questions are based on basic concepts, so studying NCERT thoroughly and practicing MCQs is the best strategy.
No. Biology questions are generally easy to moderate in difficulty. They test factual knowledge and basic understanding of topics like human anatomy, plants, and diseases – not advanced scientific theories or diagrams.
Given below is a simple 3-step revision plan:
Revise NCERT summaries for each chapter.
Practice previous year Biology questions from RRB Group D and NTPC papers.
Use short notes or flashcards for quick recall of terms like hormones, diseases, organs, and processes.
