Class XI Biology Syllabus Overview
Let’s examine the key chapters in Class XI, highlighting essential concepts, NEET’s focus areas, and how to tackle each topic effectively.
UNIT I: Diversity in the Living World
The Living World
This chapter explores the characteristics of life, from cellular organization to metabolism and consciousness. NEET often tests on definitions and the concept of biodiversity. Questions might include identifying unique features of living organisms and examples of classification.
Biological Classification
Understanding the classification of organisms, from kingdoms to species, is crucial. The five-kingdom classification proposed by Whittaker, including Monera, Protista, Fungi, Plantae, and Animalia, is a NEET favorite. Reviewing this classification system, the hierarchy of taxonomic groups, and the general features of each kingdom will boost your NEET preparation.
Plant Kingdom
This chapter covers the classification of plants, including algae, bryophytes, pteridophytes, gymnosperms, and angiosperms. NEET questions often center on characteristics, reproduction, and examples of plant groups. Be sure to focus on the alternation of generations and distinguishing features of each group.
Animal Kingdom
Animal classification, from simple sponges to complex vertebrates, is another critical area. Review the characteristics of each phylum, focusing on body symmetry, coelom types, and examples of animals in each category. Comparative anatomy is frequently tested, making this section important for scoring well.
UNIT II: Structural Organization in Plants and Animals
Morphology of Flowering Plants
This chapter dives into the external structure of flowering plants, covering roots, stems, leaves, flowers, and fruits. NEET questions often ask about the functions and adaptations of these structures. Practice identifying these parts and understanding their functions to answer related questions accurately.
Anatomy of Flowering Plants
Focusing on the internal structure of plants, this chapter discusses tissues, vascular bundles, and secondary growth. Key concepts like xylem, phloem, and the function of different tissue types frequently appear in NEET questions, making them essential study topics.
Structural Organization in Animals
In this chapter, students explore animal tissues like epithelial, connective, muscular, and nervous tissues. Each tissue type has unique functions and characteristics, often tested in NEET. Pay special attention to the structure and functions of tissues for a solid understanding.
UNIT III: Cell – Structure and Functions
Cell: The Unit of Life
The basic unit of life, the cell, is a fundamental concept. NEET questions may cover cell theory, cell structure, and the differences between prokaryotic and eukaryotic cells. Familiarize yourself with organelles like mitochondria, chloroplasts, and the nucleus for better accuracy.
Bio-Molecules
This chapter explains the structure and functions of biomolecules, including carbohydrates, proteins, lipids, and nucleic acids. NEET focuses on their structure, function, and examples, making it essential to grasp these molecules’ roles in biological systems.
Cell Cycle and Cell Division
Covering cell cycle stages, including mitosis and meiosis, this chapter is crucial for understanding growth and reproduction. Questions often test knowledge of each phase, especially the differences between mitosis and meiosis.
UNIT IV: Plant Physiology
Transport in Plants
Here, students learn about water and nutrient movement within plants, including concepts like osmosis, diffusion, and transpiration. NEET questions frequently address transport mechanisms and factors affecting them.
Mineral Nutrition
Essential minerals and their functions in plants are the focus here. Learn which minerals are macronutrients and micronutrients, as well as their deficiencies, which often appear in NEET questions.
Photosynthesis in Higher Plants
Understanding photosynthesis, including light and dark reactions, is key. NEET questions on this topic test students’ knowledge of the Calvin cycle, chloroplast structure, and factors influencing photosynthesis.
Respiration in Plants
This chapter explains how plants obtain energy through glycolysis, the Krebs cycle, and the electron transport chain. NEET frequently asks about these pathways, so mastering them is beneficial.
Plant Growth and Development
Focusing on growth regulators like auxins and gibberellins, this chapter is another NEET staple. Study plant hormones, photoperiodism, and vernalization for a complete understanding.
UNIT V: Human Physiology
Digestion and Absorption
This chapter dives into the human digestive system, covering the function and structure of each part, enzyme action, and nutrient absorption. NEET questions often center around digestive processes and related enzymes.
Breathing and Exchange of Gases
This unit covers respiration and gas exchange mechanisms in humans. Focus on the structure of the respiratory system, the mechanism of breathing, and how oxygen and carbon dioxide are transported in the blood.
Body Fluids and Circulation
The circulatory system, including the structure and function of the heart, blood vessels, and blood composition, is another key area. NEET questions often cover blood types, cardiac cycles, and disorders.
Excretory Products and Their Elimination
Understanding the human excretory system, particularly the structure of kidneys and urine formation, is essential. Questions on the functions of nephrons and waste elimination are common in NEET exams.
Locomotion and Movement
This chapter includes skeletal and muscular systems, focusing on types of muscles and joints, muscle contraction, and locomotion mechanisms. NEET frequently tests on the differences between muscle types.
Neural Control and Coordination
The human nervous system, including the brain and reflex arcs, is essential for NEET. Study the function of neurons and neurotransmitters for effective NEET preparation.
Chemical Coordination and Integration
Covering the endocrine system, this chapter examines hormones and their roles. NEET questions often focus on glands, hormone functions, and disorders related to hormonal imbalance.
Class XII Biology Syllabus Overview
UNIT VI: Reproduction
Reproduction in Organisms
Focusing on the basics of reproduction, including asexual and sexual methods, this chapter is foundational. NEET questions may cover reproductive terms and examples.
Sexual Reproduction in Flowering Plants
This chapter includes pollination, fertilization, and fruit development. NEET often tests on the structure and function of reproductive organs in plants.
Human Reproduction
Covering the human reproductive system, this chapter explains male and female reproductive organs, gametogenesis, and menstrual cycles. NEET questions frequently focus on reproductive processes and embryo development.
Reproductive Health
Topics in contraception, STD prevention, and infertility treatments are covered here. NEET questions may explore reproductive health measures and societal impacts.
