| 1. | Some properties & Functions of the Cell | contd from 1st term … 1. Cellular respiration (i) definition of cellular respiration (ii) aerobic respiration (catabolism); Krebs cycle (iv) energy released during respiration 2. Anabolism – usefulness of food. 3. Autotrophy (i) photosynthesis (ii) chemosynthesis 4. Hetrotrophy 5. Role of enzymes 6. Excretion 7. Excretory organelles in living cells (i) waste products of metabolic activities of living cells (ii) forms in which waste products are excreted 8. Growth – basis of growth-cell division (mitosis) enlargement and differentiation – regulation of growth by hormones 9. Cell reactions to its environment (i) Irritability as basic characteristics of the protoplasm (ii) Types of responses 10. Movement: (i) Cyclosis (ii) Ogranelles for movement (iii) Growth movement as regulated by auxins 11. Reproduction: Forms of reproduction a. Asexual: – Fission – Budding – Vegetative propagation b. Sexual: – Conjugation – Fusion of male and female gametes, meiosis, structure and functions of the male and female garments. |

| 2. | Tissues & Supporting Systems | 1. Skeleton and supporting systems in animals: – Biological significance – Forms e.g. chitin, cartilages and bones 2. Types of skeleton: – Hydrostatic skeleton – Exo-skeleton – Endo-skeleton 3. Vertebrate skeletons: – the skull – sternum and ribs – limb girdles – limbs 4. Bones of the vertebral column 5. Different types of supporting tissues in plants: – location and arrangement of structural components. 6. Functions of skeleton in animals – protection – support – locomotion 7. Functions of supporting tissues in plants: – strength – rigidity – resistance against the forces of wind and water |
| 3. | Nutrition in Animals | 1. Food Substances a. Types of food substances – Carbohydrates – Fats and Oils – Proteins – Mineral salts – Vitamins – Water b. Balanced diet c. Heterotrophic Nutrition 2. Types of heterotrophic nutrition – Holozoic nutrition – Saprophytic nutririon – Parasitic nutrition 3. Feeding mechanisms in holozoic organisms – Filter feeding – Deposit feeding – Fluid feeding 4. Mammalian teeth: a. The different types of teeth – incisors – Canines – Premolars – Molars b. Structure of a tooth c. Dental formula d. Adaptations of dentition to mode of nutrition 5. Enzymes: – what are enzymes – characteristics of enzymes – classification of enzymes importance of enzymes |

Ecosystem – Components & Sizes: (i) Ecological concepts – environment – biosphere – lithosphere – hydrosphere – atmosphere – habitats – niche – population – biotic community (biome) – ecosystem (ii) Components of an ecosystem – abiotic, biotic, aquatic, terrestrial 2. Local biotic communities or biomes (i) Tropical rainforest (ii) Southern guinea savanna (iii) Northern guinea savanna (iv) Sahel Savanna (v) Desert (vi) Swamp/estuarine regions 3. Major biomes of the world: (i) Tropical forest (ii) Savanna (iii) Desert (iv) Shrub (v) Afro-alpine (vi) Swamp |
