Human and Plant Physiology cover a broad area of Biology Syllabus for NEET. Interestingly, these two are hot portion of entire Biology for most of the students. Here I discuss about which are the most important topic of Human and Plant Physiology for NEET 2022.
Importance of Physiology in NEET Biology Syllabus
We all are well known that NEET-UG Biology Syllabus is completely NCERT based and the reality is that maximum Biology questions, coming in NEET are NCERT based. So, here I discuss all the points as per Biology NCERT Text book.
6 to 9 MCQ have been asking from Plant Physiology on every year. Last year, 9 MCQ have asked. The weightage of Human Physiology for NEET is much high, 16% of Biology Questions paper are set from here. Every year 12 to 15 MCQ have been asking from Human Physiology. 13 MCQ have asked, last year in NEET 2020.
| Physiology | Weightage |
|---|---|
| Plant Physiology | 6 – 9 MCQ |
| Human Physiology | 12 – 15 mcq |
Plant Physiology is explained under five chapters in unit fourth of Biology NCERT Class 11 Text book while Human Physiology is covered within seven chapters in unit fifth of Biology NCERT Class 11 Text book.
Important Topics of Plant Physiology for NEET
Plant Physiology is devided into five chapters. “Transport in Plants“, “Photosynthesis in Higher Plants” and “Respiration in Plants” are some most important Chapters for NEET 2021.
Transport in Plants
This is one of the most important chapter of Plant Physiology for NEET 2021. Every year 2 to 3 MCQ come from here. The chapter contain 6 topics which are divided into so many sub topics. The important topics are —
- Facilitated Diffusion
- Active Transport
- Water Potential
- Plasmolysis
- Apoplastic & Symplastic Pathway
- Root Pressure
- Transpiration Pull
- Transpiration
- Translocation of Mineral Ions
- Mass Flow Hypothesis
Mineral Nutrition
It is the smallest chapter of Plant Physiology. 1 to 2 MCQ are seen from this chapter in every year. The most important topics are —
- Example of Macro & Micro Nutrient
- Role of Macro & Micro Nutrient
- Deficiency Symptoms – Chlorosis, Necrosis, Inhibition of Cell Division & Delay of Flowering
- Nitrogen Cycle
- Biological Nitrogen Fixation
Photosynthesis in Higher Plants
Largest chapter of Plant Physiology is “Photosynthesis”. Generally 2 to 3 MCQ ar asked every year from this chapter. The frequently asking questions topics are —
- Photosystem
- Cyclic & Non-cyclic Photophosphorylation
- Chemiosmotic Hypothesis
- Calvin Cycle
- C4 Pathway
- Photorespiration
Respiration in Plants
It is not only important chapter of Plant Physiology but also a basic chapter of whole biology because this physiological activity is common for all the living organisms including Human. Every year 2 to 3 MCQ are seen from here in NEET. The important topics are —
- Glycolysis
- Krebs Cycle
- Electron Transport System (ETS)
- Fermentation
Plant Growth and Development
This is last chapter of Plant Physiology. Normally 1 to 3 questions are seen in every year from this chapter. “Plant Hormone” is a hot topic in this chapter from where, minimum one MCQ is obviously asked in every year. From this chapter the important topics are —
- Growth Rates
- Differentiation, Dedifferentiation & Redifferentiation
- Plant Hormones
- Photoperiodism
- Vernalisation
Important Topics of Human Physiology for NEET
Human Physiology contains 7 chapters which all are very important for NEET, as this portion cover near about 16% of the whole biology questions paper. Though the questions are asked from all the chapters of Human Physiology generally, some chapters have more weightage than others. They are “Body Fluids and Circulation“, “Neural Control and Coordination” and “Chemical Coordination and Integration“.
Digestion and Absorption
Human Physiology is started with Digestion and Absorption. Average 1 to 3 questions are asked from here in every year. The important topic from this chapter are —
- Alimentary Canal
- Digestive Glands
- Digestive Enzyme
- Absorption
- Digestive System Disorder
Breathing and Exchange of Gases
Basically Human Respiration is described under this chapter. Every year 1 to 2 questions are coming from this chapter. The important topics are —
- Respiratory Mechanism
- Respiratory Volumes & Capacities
- Exchange of Oxygen & Carbon dioxide
- Oxygen dissociation curve
- Regulation of Respiration
- Respiratory Disorder
Body Fluids and Circulation
The chapter is divided into two parts – Physiology of Blood & Lymph and Human Circulatory system. From this chapter 2 to 3 questions are asking in every year. Important portions are —
- RBC, WBC & Platelets characteristics
- Blood Groups
- Heart
- Cardiac Cycle
- ECG
- Circulatory System Disorder
Excretory Products and Their Elimination
This chapter gives 1 to 2 questions in every year. The highlighted topics are —
- Kidney
- GFR
- Functions of Tubules
- Counter Current Mechanism
- Kidney Function Regulation
- Excretory System Disorder
Locomotion and Movement
This chapter have two portion. 1st portion is talking about Muscle Physiology while the 2nd portion is all about Human Skeletal System. Every year minimum one questions are come from each portion. Anyway the targeted topics for NEET 2021 are —
- Types of Muscles
- Muscle anatomy
- Contractile Proteins – Actin, Myosin, Troponin & Tropomyocin
- Muscle Contraction Mechanism
- Skull Bones
- Vertebral Bone
- Ribs & Sternum
- Pectoral & Pelvic Girdle
- Joints
- Muscular & Skeletal Disorder
Neural Control & Coordination
This chapter contain many important topics. Generally 1 to 3 questions are coming from here. Important topics are —
- Human Neural System
- Neuron
- Nerve Impulse Conduction & Transmission
- Brain
- Eye
- Ear
Chemical Coordination and Integration
The most important and largest chapter of Human Physiology is “Chemical Coordination and Integration”. Actually all the topics are equally important here. Despite that I suggest the topic below which are most frequently asking —
- Pituitary Gland
- Pineal Gland
- Thyroid Gland
- Adrenal Gland
- Pancreas
- Mechanism of Hormone Action
The discussion mentioned above is just for guidance purposes by which one can prepare strategically for NEET. It is not give any guarantee that all the questions of Physiology come from the above mentioned topics only. The questions will come from anywhere from the entire Biology Syllabus. So, One should prepare for all the topics of Human and Plant Physiology to attempt all the questions of Physiology which will come in NEET 2022.
