NCERT Solutions for Class 11 Biology

Class 11th Biology is a vast and essential subject of class 11th Science, therefore it is important for students to study hard and get their concepts crystal clear. Biology is a subject which involves the study of life and living organisms, their physical and chemical structures, internal functions and mechanisms, growth, habitat influence and evolution. It is a depth study from plant and animals to neutral functions and chemical coordination of the organisms. Students need to do hand-in-hand practice and continuous revisions to score well in this particular subject. 

Biology is one of the most favourite and promising subject for majority of Science, medical science, biotechnology and life science oriented students. Class 11th is linked with stream based electives. Those students who want to shape career in Medical Science as well as in other professional fields after 12th are eligible for PCB/PCMB syllabus. On the basis of 10th board results students are segregated in their school respective sections. The present syllabus of 11th Biology provides the students with new concepts along with an extended exposure to contemporary areas of the subject. The syllabus also aims at emphasizing the underlying principles that are common to both animals and plants as well as highlighting the relationship of Biology with other areas of knowledge. The format of the syllabus allows a simple, clear, sequential flow of concepts. It relates the study of biology to real life through the use of technology. It links the discoveries and innovations in biology to everyday life such as environment, industry, health and agriculture. The updated syllabus also focuses on reducing the curriculum load while ensuring that ample opportunities and scope for learning and appreciating basic concepts of the subject continue to be available within its framework. 

11th Biology syllabus is vast with 22 chapters. The prescribed syllabus is expected to: 

•    Promote understanding of basic principles of Biology with the understanding of classification, morphology, anatomy of plants and animals, cells, cell cycle, biomolecules, plant & animal physiology. 
•    Encourage learning of emerging knowledge and its relevance to individual and society; 
•    Promote rational/scientific attitude towards issues related to population, environment and development; 
•    Enhance awareness about environmental issues, problems and their appropriate solutions; 
•    Create awareness amongst the learners about diversity in the living organisms and developing respect for other living beings

It is expected that the students would get an exposure to various branches of Biology in the syllabus in a more contextual and friendly manner as they study its various units.

Final paper -> Theory 70 mks + Practical 30 mks = 100 mks

List of Experiments 

1. Study and description of three locally available common flowering plants, one from each of the families Solanaceae, Fabacceae and Liliaceae (Poaceae, Asteraceae or Brassicaceae can be substituted in case of particular geographical location) including dissection and display of floral whorls, anther and ovary to show number of chambers (floral formulae and floral diagrams). Types of root (Tap and adventitious); stem (herbaceous and woody); leaf (arrangement, shape, venation, simple and compound). 
2. Preparation and study of T.S. of dicot and monocot roots and stems (primary). 
3. Study of osmosis by potato osmometer. 
4. Study of plasmolysis in epidermal peels (e.g. Rhoeo leaves). 
5. Study of distribution of stomata in the upper and lower surface of leaves. 
6. Comparative study of the rates of transpiration in the upper and lower surface of leaves. 
7. Test for the presence of sugar, starch, proteins and fats. Detection in suitable plant and animal materials. 
8. Separation of plant pigments through paper chromatography. 
9. Study of the rate of respiration in flower buds/leaf tissue and germinating seeds. 
10. Test for presence of urea in urine. 
11. Test for presence of sugar in urine. 
12. Test for presence of albumin in urine. 
13. Test for presence of bile salts in urine. 

Importance of NCERT book: It’s our observation that most of our students are diverted in different reference books available in market without revising NCERT book. 11th final paper is typically based on NCERT content, topics and questions of chapter wise exercises. 
Students need to practice all questions of NCERT book + important topics given and suggested by concerned faculty. 

In Biology revise and practice important diagrams/figures those representing the T.S of dicot stem, monocot stem, monocot root, dicot root, monocot and dicot leaves, cell cycle, Nucleic acid, Enzyme active site, Organelles, Digestive system, respiratory system, excretory system, human heart, nervous system, nerve conduction etc  • 
• Biology includes some tough terminologies which can be memorised by repetitive revisions only. 

Sequence of preparation:

1.    NCERT Book
2.    NCERT Exemplar book based all questions of 1 mk, 2mks, 3 mks & 5 mks.
3.    Follow Studymate book, class notes, Studymate worksheets, assignments.
4.    Studymate test papers, quarterly test papers, unit papers, full length papers and Biology extensive test papers attempt is critically important.
5.    Studymate lecture wise worksheets, “Question bank” are designed to enhance writing and presentation skills of students.
6.    For getting 95-100% mks in Biology its necessary to make a balance of theory and practicals.
