Plant Physiology is an important unit of NEET 2023 Biology Syllabus. Here I have discussed all the most important topics of Plant Physiology for NEET 2023 in detail.
NEET 2023
NEET 2023 is one of the highest competitive exam for admission in medical college of India. National Testing Agency (NTA), a government agency of Education Ministry (India) conduct NEET UG 2023 for the admission of medical undergraduate courses like MBBS, BDS, BHMS, BAMS, BUMS, BVSc, BPT etc.
Biology for NEET 2023
The question paper of NEET UG contain four subjects : Physics, Chemistry, Botany and Zoology. Botany and Zoology belong to the subject Biology which is a key factor for getting high score in NEET. The syllabus of the Botany and Zoology are prepared on the basis of class 11th and 12th Biology NCERT Syllabus.
Plant Physiology for NEET 2023
Plant Physiology is an important unit of Botany. According to NCERT syllabus it is the 4th unit of class 11th Biology. This unit is divided into five chapters :
- Transport in Plants
- Mineral Nutrition
- Photosynthesis in Higher Plants
- Respiration in Plants
- Plant Growth and Development
There are several topics from these five chapters which are very important for NEET. Every year 6 to 9 questions are asked in NEET from this five chapters. You can also check The Questions Weightage of Each & Every Chapter of Biology for NEET. So, in this article I have mentioned all the most important topics of Plant Physiology for NEET 2023.
Transport in Plants
The first chapter of Plant Physiology is Transport in Plants. Every year 2 to 3 MCQ come from here. According to the NEET Biology Syllabus, the most important topics of Plant Physiology for NEET 2023 from this chapter are :
- Diffusion
- Facilitated diffusion
- Active transport
- Water potential
- Imbibition
- Plasmolysis
- Apoplast and Symplast
- Transpiration pull
- Root pressure
- Guttation
- Transpiration factor
- Opening and closing of stomata
- Mass flow hypothesis
Mineral Nutrition
The second chapter of Plant Physiology is Mineral Nutrition. It is the smallest chapter of Plant Physiology. 1 to 2 MCQ are asked in NEET from this chapter in every year. According to the NEET Biology Syllabus, the most important topics of Plant Physiology for NEET 2023 from this chapter are :
- Hydroponics
- Example of Macro & Micro Nutrients
- Role/function of Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Sulphur (S), Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu), Boron (B), Molybdenum (Mo) and Chlorine (Cl).
- Deficiency Symptoms – Chlorosis, Necrosis, Inhibition of Cell Division & Delay of Flowering
- Manganese (Mn) toxicity
- Nitrogen Cycle
- Biological Nitrogen Fixation
Photosynthesis in Higher Plants
The third chapter of Plant Physiology is Photosynthesis in Higher Plants. It is the largest chapter of Plant Physiology. Generally 2 to 3 MCQ are asked every year from this chapter. According to the NEET Biology Syllabus, the most important topics of Plant Physiology for NEET 2023 from this chapter are :
- Photosystem
- Cyclic & Non-cyclic Photophosphorylation
- Chemiosmotic Hypothesis
- Calvin Cycle (C3 Pathway)
- C4 Pathway
- Photorespiration
- Factor affecting photosynthesis
Respiration in Plants
The fourth chapter of Plant Physiology is 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. According to the NEET Biology Syllabus, the most important topics of Plant Physiology for NEET 2023 from this chapter are :
- Glycolysis
- Fermentation
- Link reaction
- TCA Cycle (Krebs Cycle)
- Electron Transport System (ETS)
- ATP calculation
- Amphibolic pathways
- Respiratory quotient (RQ)
Plant Growth and Development
The last chapter of Plant Physiology is Respiration in Plants. 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 According to the NEET Biology Syllabus, the most important topics of Plant Physiology for NEET 2023 from this chapter are :
- Phases of Growth
- Growth Rates
- Differentiation, Dedifferentiation & Redifferentiation
- Heterophylly
- Discovery of Phytohormone
- Plant hormone : Auxin, Gibberellin, Cytokinin, Ethylene & Abscisic acid
- Photoperiodism
- Vernalisation
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 Plant Physiology come from the above mentioned topics only. The questions will come from anywhere of the entire Biology Syllabus. So, One should prepare for all the topics of Plant Physiology to attempt all the questions of Plant Physiology which will come in NEET 2023.
