Summary

• Description:

  The PDF document comprises a complete set of Form 1 Biology Notes, covering all major topics for the year.

  The topics and sub-topics covered in the document include:

  1. Introduction to Biology

  • Definition and branches of Biology (e.g., Botany, Zoology, Genetics).

  • The importance of studying Biology and its related careers.

  • Characteristics of living things (Nutrition, Respiration, Growth, etc.).

  • Collection, observation, and drawing of organisms.

  • A basic comparison between plants and animals.

  2. Classification I

  • The necessity for classifying organisms.

  • The major units of classification (Kingdom, Phylum/Division, Class, Order, Family, Genus, Species).

  • An overview of the five kingdoms: Monera, Protoctista, Fungi, Plantae, and Animalia.

  • The principles of Binomial Nomenclature for scientific naming.

  • Practical activities on collecting and observing specimens.

  3. The Cell

  • The microscope: A detailed look at the parts, functions, and care of the light microscope.

  • Cell structure as seen under both light and electron microscopes.

  • Functions of various organelles like the nucleus, mitochondria, and chloroplasts.

  • A comparison of plant and animal cells.

  • Cell specialization and the organization of cells into tissues, organs, and organ systems.

  4. Cell Physiology

  • The structure and properties of the cell membrane.

  • Key physiological processes: Diffusion, Osmosis, and Active Transport.

  • Factors affecting each process and their roles in living organisms.

  • Water relations in cells, including turgor, plasmolysis in plant cells, and crenation/haemolysis in animal cells.

  • Practical activities to demonstrate these processes.

  5. Nutrition in Plants and Animals

  • Plant Nutrition: The external and internal structure of a leaf, its adaptations for photosynthesis, the structure of a chloroplast, and the process of photosynthesis (light and dark stages).

  • Animal Nutrition: Types of heterotrophism, dentition in mammals (herbivores, carnivores, omnivores), dental diseases, and a detailed study of the human digestive system, including digestion, absorption, and assimilation.

  • Food and Diet: The chemical nature of carbohydrates, proteins, and lipids; the role of enzymes; and the importance of a balanced diet, including vitamins, mineral salts, and water.

  These notes provide a thorough and complete guide to the Form 1 Biology syllabus, covering topics from all three terms. They are well-organized, neat, and printable, featuring clear diagrams, tables, and practical activity guides. This makes them an excellent and comprehensive resource for students for their year-long study and KCSE revision, as well as for teachers in preparing their lessons.
