Study Notes
NEET - Biology Concepts
1. Cell Biology
-
Cell Structure: Prokaryotic vs Eukaryotic cells.
- Prokaryotic: No nucleus, simple structure (e.g., bacteria).
- Eukaryotic: Nucleus, membrane-bound organelles (e.g., plant and animal cells).
-
Cell Organelles: Functions of key organelles.
- Nucleus: Controls cell activities, stores DNA.
- Mitochondria: Energy production (ATP synthesis).
- Ribosomes: Protein synthesis.
- Endoplasmic Reticulum: Rough (protein synthesis) vs Smooth (lipid synthesis).
2. Genetics
-
Mendelian Genetics:
- Law of Segregation: Separation of alleles during gamete formation.
- Law of Independent Assortment: Genes for different traits segregate independently.
-
Genotypes and Phenotypes:
- Genotype: Genetic makeup (e.g., homozygous, heterozygous).
- Phenotype: Physical expression of traits.
- Punnett Squares: Predicting genetic variations and inheritance patterns.
3. Human Physiology
-
Organ Systems: Main functions of body systems.
- Circulatory System: Transports nutrients, gases, hormones.
- Respiratory System: Gas exchange (O2 and CO2).
- Digestive System: Breaks down food, nutrient absorption.
- Nervous System: Coordinates body responses and processes information.
- Homeostasis: Maintenance of stable internal conditions (temperature, pH).
4. Ecology
-
Ecosystems: Interaction between organisms and their environment.
- Biotic factors: Living components (plants, animals).
- Abiotic factors: Non-living components (water, temperature).
-
Food Chains and Food Webs:
- Producers (plants) → Consumers (herbivores, carnivores).
- Trophic levels: Energy flow within ecosystems.
5. Evolution
-
Natural Selection: Mechanism of evolution.
- Variability: Different traits in a population.
- Survival of the fittest: Better adapted individuals survive and reproduce.
- Speciation: Formation of new species through evolution.
6. Plant Physiology
-
Photosynthesis: Process by which plants convert light energy to chemical energy.
- Light-dependent reactions: Occur in thylakoids, produce ATP and NADPH.
- Light-independent reactions (Calvin Cycle): Occur in stroma, synthesize glucose.
-
Plant Hormones: Key hormones and their functions.
- Auxins: Promote cell elongation.
- Gibberellins: Stimulate growth and seed development.
- Abscisic acid: Involved in stress responses.
7. Biotechnology
-
Techniques: Key biotechnological methods.
- DNA cloning: Creating copies of DNA sequences.
- PCR (Polymerase Chain Reaction): Amplifying DNA for analysis.
- Gene editing (CRISPR): Modifying genes for research or therapeutic purposes.
- Applications: Use in medicine, agriculture, and environmental protection.
8. Microbiology
- Types of Microorganisms: Bacteria, viruses, fungi, and protozoa.
-
Important Concepts:
- Pathogenic vs Non-pathogenic: Disease-causing vs beneficial organisms.
- Antibiotic resistance: Mechanisms and implications in treatment.
9. Human Anatomy
-
Key Systems: Overview of important body systems and structures.
- Skeletal System: Structure (bones, joints) and function (support, protection).
- Muscular System: Types of muscles (skeletal, smooth, cardiac) and their roles in movement.
- Reproductive System: Male and female structures, functions, and processes (fertilization, gestation).
These key concepts provide a foundational understanding of the biology topics relevant to NEET preparation.
