Key Chapters for NEET 2019 in Plant and Human Physiology: Understanding and Preparation Tips

The National Eligibility cum Entrance Test (NEET) 2019 for Biology includes a wide range of topics under Plant and Human Physiology. While the exact weightage of each chapter can vary slightly from year to year, here are some of the most important and frequently tested chapters in these areas.

Plant Physiology

Transport: Movement of water, minerals, and solutes in plants

Transport in plants is a crucial process that ensures the proper distribution of water, minerals, and solutes throughout the plant. This includes both passive (osmosis and diffusion) and active transport mechanisms.

Mineral Nutrition: Essential elements uptake and transport

Mineral nutrition is fundamental to plant growth and development. Understanding the types of essential elements, their sources, and how they are absorbed and transported is critical.

Photosynthesis: Process of photosynthesis, light and dark reactions

Photosynthesis is one of the most important processes in plant physiology. It involves the conversion of light energy into chemical energy. The light reactions and dark reactions (Calvin cycle) are key components of this process.

Respiration: Cellular respiration, glycolysis, Krebs cycle, and electron transport chain

Respiration is a vital process in plants, involving the breakdown of organic compounds to release energy. This includes glycolysis, the Krebs cycle, and the electron transport chain.

Growth and Development: Plant growth regulators, seed germination, flowering, and senescence

The understanding of growth regulators, the stages of plant growth, and the processes of seed germination, flowering, and senescence is crucial for success in the NEET 2019.

Human Physiology

Digestion: Digestive system, enzymes, and digestion processes

The digestive system plays a key role in breaking down food into nutrients. Understanding the different digestive enzymes and the processes of digestion is essential.

Respiration: Respiratory system, gas exchange, and transport

Respiration involves the exchange of gases (oxygen and carbon dioxide) and their transport in the body. This includes the respiratory system and the process of cellular respiration.

Circulation: Blood circulatory system, heart, and blood vessels

The circulatory system is vital for the transport of oxygen, nutrients, and waste products. Understanding the structure and function of the heart and blood vessels is crucial.

Excretory System: Excretory organs, urine formation, and osmoregulation

The excretory system plays a vital role in removing waste products and maintaining osmotic balance. Knowledge of the nephron structure and the formation of urine is important.

Locomotion and Movement: Muscular system, types of muscles, and skeletal system

Understanding the muscular and skeletal systems, including the types of muscles and how they function, is key to understanding locomotion and movement.

Nervous System: Nervous tissue, brain, spinal cord, and reflexes

The nervous system is responsible for communication in the body. Understanding the structure and function of the brain, spinal cord, and the mechanisms of reflexes is important.

Endocrine System: Hormones, endocrine glands, and their functions

Endocrine glands produce hormones that regulate various physiological processes. Understanding the functions of different endocrine glands and the hormones they produce is crucial.

Reproduction: Reproductive system, reproductive processes, and development

The reproductive system involves processes of reproduction and development. Understanding the structure and function of the reproductive system is important.

Study Tips

1. Prioritize Understanding Concepts: Focus on understanding the underlying concepts and processes rather than just memorizing facts. Concepts such as cellular respiration, photosynthesis, and the circulatory system are fundamental to many questions.

2. Practice with Previous Years’ Question Papers: Familiarize yourself with the question patterns by practicing with previous years’ NEET question papers. This will help you understand the types of questions asked and the format of the exam.

3. Thorough Coverage of the Syllabus: While these are some of the most heavily weighted chapters, it is essential to cover the entire syllabus thoroughly. The weightage of topics can vary slightly from year to year.

By focusing your studies on these chapters and following the above tips, you can enhance your preparation for the NEET 2019 and improve your chances of success.
