Chapter 3: Plant Kingdom – Salient features and classification of Algae, Bryophytes, Pteridophytes, and Gymnosperms.
Chapter 4: Animal Kingdom – Classification of animals from non-chordates (phyla level) to chordates (class level).
Unit II: Structural Organisation in Plants and Animals (10 Marks)
Chapter 5: Morphology of Flowering Plants – Study of roots, stems, leaves, inflorescence, flowers, fruits, and seeds.
Chapter 6: Anatomy of Flowering Plants – Internal structures and plant tissue systems (meristematic and permanent).
Chapter 7: Structural Organisation in Animals – Focuses on animal tissues; specific study of the morphology and anatomy of a frog.

Unit V: Human Physiology (18 Marks)
Chapter 14: Breathing and Exchange of Gases – Respiratory system mechanism and disorders.
Chapter 15: Body Fluids and Circulation – Blood composition, human circulatory system, and cardiac cycle.
Chapter 16: Excretory Products and Their Elimination – Human excretory system and kidney function regulation.
Chapter 17: Locomotion and Movement – Types of movement, skeletal system, and muscle contraction.
Chapter 18: Neural Control and Coordination – Neuron structure, nerve impulse conduction, and sense organs.
