Rajasthan Board of Secondary Education (the RBSE) has prepared a comprehensive syllabus for Class 11 Biology for the board exam of 2021-22. It is a must that students study and analyze the syllabus before they start studying the subject. Moreover, a sound understanding, knowledge, and application of chapters and concepts given in Class 11 is important for further studies. Therefore, in this article, we will take a detailed look at the Rajasthan Board Class 11 Biology syllabus to better understand what all chapters are to be covered.
Biology is one of the most interesting yet challenging subjects in Class 11. The entire subject of 100 marks is divided into two papers — theory paper of 70 marks and practical of 30 marks. Basics of the subject studied in previous classes will help the students in building a strong base and understanding of the chapters in Class 11.
Rajasthan Board Class 11 Biology Theory Syllabus
The entire syllabus has been divided into 5 major units. These units have been provided below:
| S.No. | Unit Name | Number of Chapters in the Unit | |
| 1. | Diversity in the Living World | 4 | |
| 2. | Structural Organisation in Plants and Animals | 3 | |
| 3. | Cell- Structure and Functions | 3 | |
| 4. | Plant Physiology | 5 | |
| 5. | Human Physiology | 7 | |
| Total | 22 chapters |
Plant Physiology and Human Physiology are the longest units and thus carry the most weightage. The unit ‘Plant Physiology’ is essential for understanding the practical work in the laboratories as well.
Given below is the list of chapters–
| Chapter 1 — The Living World |
| Chapter 2 — Biological Classification |
| Chapter 3 — Plant Kingdom |
| Chapter 4 — Animal Kingdom |
| Chapter 5 — Morphology of Flowering Plants |
| Chapter 6 — Anatomy of Flowering Plants |
| Chapter 7 — Structural Organisation in Animals |
| Chapter 8 — Cell: The Unit of Life |
| Chapter 9 — Biomolecules |
| Chapter 10 — Cell Cycle and Cell Division |
| Chapter 11 — Transport in Plants |
| Chapter 12 — Mineral Nutrition |
| Chapter 13 — Photosynthesis in Higher Plants |
| Chapter 14 — Respiration in Plants |
| Chapter 15 — Plant Growth and Development |
| Chapter 16 — Digestion and Absorption |
| Chapter 17 — Breathing and Exchange of Gases |
| Chapter 18 — Body Fluids and Circulation |
| Chapter 19 — Excretory Products and their Elimination |
| Chapter 20 — Locomotion and Movement |
| Chapter 21 — Neural Control and Coordination |
| Chapter 22 — Chemical Coordination and Integration |
Rajasthan Board Class 11 Biology Practical Syllabus
The practical syllabus has not been reduced from the previous year. The following experiments must be performed in the lab:
1. Preparation and study of T.S. of dicot and monocot roots and stems.
2. To study types of the root (tap and adventitious); stem (herbaceous and woody); leaf (arrangement, shape, venation, simple, and compound).
3. Study of osmosis by potato osmometer.
4. Study of plasmolysis in epidermal peels
5. Comparative study of the rates of transpiration in the upper and lower surface of leaves.
6. Test for the presence of sugar, starch, proteins, and fats.
7. Test for the presence of urea in urine.
8. Test for the presence of bile pigment in urine.
The student must also undertake the observational study of the following:
1. Study of tissues and diversity in shapes and sizes of the plant cell (palisade cells, guard cells, parenchyma, collenchyma, sclerenchyma, xylem, phloem)
2. Study of different modifications in roots, stems, and leaves.
3. Study and identification of different types of inflorescence.
4. Study of imbibition in seeds/raisins.
5. Observation and comments on the experimental set up for showing a) Anaerobic respiration b) Photoperiodism c) Effect of apical bud removal d) Suction due to transpiration.
6. Study of the human skeleton and different types of joints with the help of virtual images/models only
The use of live models may be substituted entirely by virtual models for online learning. Some lab studies can be undertaken entirely virtually. The students must submit their lab work and observations before the final exam on the dates released by their respective schools. There may be a reduction in the practical syllabus, but that has not yet been confirmed. The Observation (Spotting) Exams have a short written component. A teacher may show a virtual specimen or a preserved or fresh specimen (such as a leaf, a petal, a seed, etc.) or a slide under a microscope and ask relevant questions. There may be an external examiner present during these exams.
The laboratory practice is a logical extension of what the students study during theory classes. The students must identify the structures and processes of plants and animal structures that are covered in the theoretical learning. This is to ensure that the students have a reasonable understanding of the biological diversity around them. The students are also expected to know the parts of a microscope and must use a microscope to observe slides. The 30 marks are divided evenly between the lab record and the spotting examination.
Frequently Asked Questions of RBSE Board Biology Class 11
1. What are some tips for the RBSE Board Class 11 Biology Exam?
Answer: Students must be familiar with the exam syllabus, question paper pattern, and should focus on crucial areas (refer to important questions, sample papers to get an idea), and stick to a study schedule to prepare for the exam. They must also devote a significant amount of time to revising and practicing numerical problems.
2. How should students prepare for the Rajasthan Board Class 11 Biology Exam?
Answer: Students should create organized timetables for a subject like Biology. They need to study the basic concepts of Biology, which their teachers teach. After completing each topic, they should practice the questions given at the end of each chapter. After the completion of the entire Biology syllabus, they need to attempt the full-length mock tests properly. These will help students revise the concepts for their final examinations
3. When do I have to submit my practical file?
Your school will give you dates to submit your practical files/notebooks. Please contact your school and confirm. Typically, the deadline is in the last half of January.
4. From where should students prepare for Class 11 Biology Exam?
Answer: Students can solve the Class 11 questions from their RBSE Board state text books. They can also go through the last ten years’ question papers to familiarize themselves with the entire coursework.
5. Will the examination be held online?
No, as of now, the examination is set to be held offline. Please be aware of any further notifications issued by your school. As the pandemic recedes, the schools are planning to start operating as usual. However, new plans may be undertaken as the situation develops.
