ISC Class 11 Biology Syllabus

ISC Class 11 Biology Syllabus

The students can refer to ISC Class 11 Biology Syllabus on the Extramarks website. The syllabus offers ample information pertaining to the syllabus on each essential topic. Further, the students get useful information, including the concepts, theories, and mark distribution for each case. Each topic in ISC Biology Class 11 is well elaborated with examples and fundamental principles. 

To score more incoming first-term ISC board exams, students can refer to ISC Class 11 Biology Syllabus to study. It is essential to have a good knowledge of the syllabus of the particular subject. Studying morphology, cytology, and scientific techniques is essential for a deep understanding. The students get to witness various theories in Biology. 

The students will learn about the biological classification, morphology, and anatomy of flowering plants. Further, they will also learn human physiology. They will understand the breathing and exchange of gases, body fluid and circulation, excretory products, and locomotion movements. 

Students may access the latest ISC Class 11 Biology Syllabus on Extramarks.

ISC Class 11 Biology Syllabus 2023-24 – Semester (1 & 2)

Studying from ISC Class 11 Biology Syllabus helps students grasp the concepts with better understanding. It helps them score more in the exam and perform well. Further, there are three sections in ISC Class 11 Biology Syllabus, including Section A, Section B, and Section C.

The below table offers the Class 11 Biology Syllabus and the Units under each section:

ISC Class 11 Biology Syllabus Section A:

1. Diversity of Life

• Taxonomy and phylogeny, three domains of life: binomial nomenclature.
• Five-kingdom classification: characteristics, salient features, and examples.
• Anatomy of different cockroach systems.

ISC Class 11 Biology Syllabus Section B:

2. Plant Physiology

• Mineral nutrition: macronutrients, micronutrients, criteria for the essentiality of elements, and nitrogen in plants. 
• Plant growth, phases of development, measurement of plants.
• Photomorphogenesis in plants. 

3. Multicellularity: Structure of Plants and Animals

• Plant Tissues: types of plant tissues, structure and functions of superficial tissues, types of vascular bundles.
• Animal Tissues: epithelial, connective, muscular, nervous tissues. 
• Nutrition: Calorific value of carbohydrates, organs of the digestive system, digestive process, and disorder of the digestive system. 
• Respiration: Organs of the respiratory system, pulmonary gas exchange, transport of respiratory gases. Disorders of the respiratory system. 
• Circulation: Closed and open vascular systems, the structure of the human heart, coagulation of blood. Disorders of the Circulatory system. 
• Excretion: Structure of nephron, the role of skin and lungs in excretion, kidney functions. 
• Endocrine system: Mechanism of hormone action, the effect of hyposecretion, feedback mechanism. 
• Nervous system: Central, automatic, and peripheral, the structure of the brain and spinal cord, transmission of nerve impulse. 
• Locomotion: Structure of skeletal muscle, sliding filament theory of muscle contraction. Disorder of muscular and skeletal system. 

4. Units of Life

• Biomolecules: Outline classification and functions of carbohydrates.
• Enzymes: General properties, classification, mechanism of enzyme action. 
• Cell membranes: Facilitated diffusion, membrane transport, passive and active transport. 
• Cell structure: structure and functions of nucleus, cell wall, vacuoles, and cell inclusions. Prokaryotic cell and eukaryotic cell- a comparison.
• Cellular respiration: aerobic and anaerobic fermentation, amphibolic pathway. 
• Cell reproduction: cell cycle, mitosis, and meiosis. 

ISC Class 11 Biology Syllabus Section C:

ISC Class 11 Biology Paper Pattern

As the exam approaches, students can revise the concepts, theories, and fundamental principles in biology. To score more, students can refer to ISC Class 11 Biology Syllabus. It is essential to know what type of questions will be asked in the exam. Students have to attempt one paper of three hours duration. 

Part 1 (20 Marks) is a compulsory section, and students have to attempt short answer questions. This section will test the student’s knowledge, application, and skills relating to the fundamentals aspects of the biological concepts. 

Part 2 (50 Marks) consists of three sections, including A, B, and C. The students can attempt two out of three questions in Section A (each carries five marks). Further, in Section B, they can attempt two out of three questions, each carrying ten marks. Lastly, in Section C, the students can attempt two out of three questions, each having ten marks. Thus, a total of 6 questions are required to answer in Part 2. 

ISC Class 11 Biology Syllabus & Study Materials 2023-24

To prepare for the ISC board exam and competitive exam, the student can refer to ISC Class 11 Biology Syllabus. They can also refer to the study material available on the Extramarks website. The students will get a general idea of the morphology and physiology of plants and animals. Further, they will learn about binomial nomenclature and the anatomy of different systems. 

Plant physiology is one of the essential topics in ISC Class 11 Biology Syllabus. The students will witness broader concepts such as mineral nutrition, macronutrients, and phases of plant growth. The structure and functions of plants and animals and other important topics are well elaborated on in the syllabus.
