• Learn stages of mitosis.
• Overview of meiosis and its importance.
• Differences between mitotic and meiotic divisions.

Week 2: Structure of Chromosome

• Understand the basic structure of chromosomes, including chromatin, chromatid, gene, DNA structure, and centromere.

Week 3: Mendelian Genetics

• Study Mendel’s laws of inheritance and perform monohybrid and dihybrid crosses (phenotype and genotype).
• Key terms: gene, allele, heterozygous, homozygous, dominant, recessive.

Week 4: Sex-linked Inheritance

• Learn about sex determination and X-linked diseases like haemophilia and colour blindness.

Month 2: Plant Physiology

Week 5: Absorption by Roots

• Study root structure and the processes of imbibition, osmosis, and diffusion.
• Learn the mechanism of water absorption and active/passive transport.

Week 6: Ascent of Sap and Water Conduction

• Explore cohesive and adhesive forces, root pressure, and transpirational pull.
• Conduct experiments on water conduction.

Week 7: Transpiration

• Understand transpiration, its significance, and factors affecting the rate.
• Learn related experiments (Ganong’s potometer, weight loss).

Week 8: Photosynthesis

• Study the process, structure of chloroplasts, light and dark reactions.
• Conduct experiments to show the necessity of light, CO2, and chlorophyll.

Month 3: Plant Physiology & Human Anatomy

Week 9: Photosynthesis (Continued)

• Study adaptations for photosynthesis and the carbon cycle.

Week 10: Chemical Coordination in Plants

• Learn about plant hormones (Auxins, Gibberellins, Cytokinins, etc.).
• Study tropic movements like phototropism and geotropism.

Week 11: Circulatory System

• Study blood components (RBC, WBC, platelets), tissue fluid, lymph.
• Understand the structure and function of the heart, blood vessels, and the concept of circulation.

Week 10: Excretory System

• Learn about the excretory organs, kidney structure, and nephron function.

Month 4: Human Anatomy

Week 13: Nervous System

• Study neuron structure, the central and peripheral nervous systems, and the brain’s major parts.
• Understand reflex action vs. voluntary action.

Week 14: Sense Organs (Eye and Ear)

• Learn the structure, functions, and defects of the eye and ear.

Week 15: Endocrine System

• Study major endocrine glands (Adrenal, Pancreas, Thyroid, Pituitary) and their functions.

Week 16: Reproductive System

• Learn about male and female reproductive organs, fertilisation, and the menstrual cycle.

Month 5: Evolution, Population & Pollution

Week 17: Human Evolution

• Study human ancestors and theories of evolution (Lamarck’s and Darwin’s theories).

Week 18: Population

• Understand population explosion, reasons, problems, and control measures.

Week 19: Pollution

• Study types of pollution (air, water, soil, etc.), pollutants, and their effects on the environment.
• Learn about control measures and climate effects (greenhouse effect, acid rain).

Week 20: Revision and Practice

• Review key topics from the syllabus.
• Practice diagrams and solve past exam papers for better understanding.
