BIOLOGY SYLLABUS FOR NEET (UG) – 2025
UNIT 1: Diversity in Living World
• What is living? ; Biodiversity; Need for classification;; Taxonomy &
Systematics; Concept of species and taxonomical hierarchy; Binomial
nomenclature;
• Five kingdom classification; salient features and classification of Monera;
Protista and Fungi into major groups; Lichens; Viruses and Viroids.
• Salient features and classification of plants into major groups-Algae,
Bryophytes, Pteridophytes, Gymnosperms (three to five salient and
distinguishing features and at least two examples of each category);
• Salient features and classification of animals-nonchordate up to phyla level and
chordate up to classes level (three to five salient features and at least two
examples).
UNIT 2: Structural Organisation in Animals and Plants
• Morphology and modifications; Tissues; Anatomy and functions of different
parts of flowering plants: Root, stem, leaf, inflorescence- cymose and recemose,
flower, fruit and seed (To be dealt along with the relevant practical of the
Practical Syllabus) Family (malvaceae, Cruciferae, leguminoceae, compositae,
graminae).
• Animal tissues; Morphology, anatomy and functions of different systems
(digestive, circulatory, respiratory, nervous and reproductive) of an insect (Frog).

, UNIT 3: Cell Structure and Function
• Cell theory and cell as the basic unit of life; Structure of prokaryotic and
eukaryotic cell; Plant cell and animal cell; Cell envelope, cell membrane, cell
wall; Cell organellesstructure and function; Endomembrane system-endoplasmic
reticulum, Golgi bodies, lysosomes, vacuoles; mitochondria, ribosomes, plastids,
micro bodies; Cytoskeleton, cilia, flagella, centrioles (ultra structure and
function); Nucleus-nuclear membrane, chromatin, nucleolus.
• Chemical constituents of living cells: Biomolecules-structure and function of
proteins, carbodydrates, lipids, nucleic acids; Enzymes-types, properties,
enzyme action, classification and nomenclature of anzymes.
• B Cell division: Cell cycle, mitosis, meiosis and their significance.
UNIT 4: Plant Physiology
• Photosynthesis: Photosynthesis as a means of Autotrophic nutrition; Site of
photosynthesis take place; pigments involved in Photosynthesis (Elementary
idea); Photochemical and biosynthetic phases of photosynthesis; Cyclic and non
cyclic and photophosphorylation; Chemiosmotic hypothesis; Photorespiration
C3 and C4 pathways; Factors affecting photosynthesis.
• Respiration: Exchange gases; Cellular respiration-glycolysis, fermentation
(anaerobic), TCA cycle and electron transport system (aerobic); Energy
relations- Number of ATP molecules generated; Amphibolic pathways;
Respiratory quotient.
• Plant growth and development: Seed germination; Phases of Plant growth and
plant growth rate; Conditions of growth; Differentiation, dedifferentiation and
redifferentiation; Sequence of developmental process in a plant cell; Growth
regulatorsauxin, gibberellin, cytokinin, ethylene, ABA;
