WEEKS 3 & 4 CLASSIFICATION OF LIVING THINGS

The focus for these two weeks will be on the various biological kingdoms.

Kingdom Monera: Prokaryotes (their characteristics).
Single — celled mobile and non mobile, as well as no definite nucleus (blue/green algae).
Kingdom protista : Eukaryotes (their characteristics) single celled mobile and non mobile. Complex cell structured with definite nucleus e.g Chlamydomoas and Amoeba.
Kingdom Plantae: Eukaryotes many celled non mobile organisms which contains chlorophyll for photosynthesis e.g firms mosses pines oil palm, yam.
Kingdom Animalia: Eukaryotes many celled mobile organisms that feed on other organisms e.g corals, worms, insects, snails, fishes, frog, snakes, monkeys, cow, cockroaches, etc.

WEEKS 5 AND 6: THE CELL AND IT’S ENVIRONMENT

In this two weeks the students will be introduced to the complex of the cell of living things. The cell will be treated under.
Cell as living units of an organism: it’s characteristics as a living unit of an organism, forms in which living cell exist-as independent organisms and as colony or as a filament.
Cell structure: The cell theory structure and functions of the components, differences and similarities between plant and animal cells
Diffusion: Definition, process and significance: experiment should be carried out.
Osmosis: Definition, diffusion through a semi-permeable membrane (experiment to demonstrate this) and biological significance of osmosis.
Other Topics: haemolysis, plasmolysis, osmoneter with living materials and biological significance of the process.

WEEKS 7,8 9 & 10: SOME PROPERTIES AND FUNCTIONS OF THE CELL

Feeding: definition and types micronutrients and macronutrients.
Cellular Respiration: Definition, Aerobics respiration (catabolism) ker cycle, Anaerobic. Respiration (Respiration, and usefulness of food).
Autotrophy: Photosynthesis and chemosynthesis
Excretion: Definition, excretory organelles in living cells, waste products of metabolic activities of living cells and forms in which waste products are excreted.
Growth: Basis of growth, cell division (mitosis), enlargement and differentiation as well as regulation of growth by hormones.

SECOND TERM BIOLOGY

DETAILED WORK

WEEKS 2 & 3: CONTINUATION OF SOME PROPERTIES AND FUNCTIONS OF THE CELL.

Cell reaction to it’s environment: Irritability as basic characteristics of the cytoplasm and types of responses.
Movement: cyclosis, organelles for movement and growth movement as regulated by Auxins.
Reproduction: asexual (fission budding and vegetative propagation) Sexual (conjugation, fusion of male and female garments) meiosis and functions of male and female gonads.

WEEKS 4, 5, 6 & 7: TISSUES AND SUPPORTING SYSTEM

Skeleton and supporting System in Animals: Biological significant and forms— chitins, cartilages and bones.
Vertebrate Skeleton: The skull, sternum, ribs, hips girdle and limbs.
Types of Skeletons: Exoskeletons and endoskeletons
Bones of the vertebral column: Functions of Skeletons in animals: protection, support and locomotion.
Supporting Tissues in plant: Types of supporting tissues in plant. Location and arrangement of structural components.
Functions of supporting tissues in plant: strength, rigidity resistance against the force of wind and water.

WEEKS 8, 9 & 10: NUTRITION IN ANIMAL

Food Substances:Types of food substance (Carbohydrate, fat and oil, protein, mineral salts, vitamins and water) balanced diet, heterotrophic nutrition and types of nutrition (holozoic saprophytic and parasitic)
Feeding mechanism in Holozoism Organism: Deposit and fluid feeding.
Mammalian Teeth: different types of teeth (incisor, cannier, premolar and molar) structure of a tooth, dental formula and adaptation of dentation to mode of nutrition.
Enzymes: Definition, characteristics, classification and importance of enzyme.

THIRD TERM BIOLOGY

DETAILS

WEEK 2, 3 & 4: BASIC ECOLOGICAL CONCEPTS.

Ecosystem components and size:Ecological concepts: environment, habitat, Biosphere, niche, lithosphere, population, hydrosphere, biotic community, Atmosphere, ecosystem biotic and terrestrial.
Local Biotic Communities or Biomes: Tropical rain forest, south guinea savanna, North Guinea savanna, Sahel, savanna, desert, swamps/Estuarine regions.
Major biomes of the world: Tropical rain forest, savanna, desert, Shrub Afro-Alpine and swamp.
Population studies by swamping method: Population, size, dominance density and factors that affect population.
Ecological Factors: Aquatic terrestrial and factors common to all habitats. Importance of ecological factors to population to animals and plants.
Relationship between soil types and water holding effect of soil and vegetation.
Simple Measurement of Ecological Factors: Physical factors-chemical & physical composition, moisture content and thickness of the soil. Measuring instrument.

WEEK 5: FUNCTIONING ECOSYSTEM

(I) AUTOTROPHY AND HETEROTROPHY
(II) FOOD WEBS AND TROPHIC LEVEL.

Autotrophy and heterotrophy: Producers Autotrophy Consumers heterotrophy. Aquatic and terrestrial examples of producers and consumers.
Trophic Level: Energy relationship, food web and non cyclic nature of chemical energy transfer.
Energy Flow: Food/energy relationship in aquatic and terrestrial environment, pyramid of energy/number nature of energy flow described by food chain.

WEEK 6: ENERGY TRANSFORMATION IN NATURE.

Energy loss in the Ecosystems loss at the Earth’s surface
Energy loss in the Biosphere, measure of primary production e.g the amount and rat of the energy fixation.
Laws of Thermodynamics: First and second law and application of both to ecological phenomena.

WEEKS 7 & 8: RELEVANCE OF THE BIOLOGY OF AGRICULTURE

Classification of plants: Botanical classification e.g algae, spermatophyte, agricultural classification based on life cycle e.g fibers, latex, etc, classification based on life cycle e.g annual perennial etc.
Effects of Agriculture Activities on Ecological systems: Bush clearing/burning tillage fertilizer/herbicide and their effects of different type of farming on ecological system.

WEEK 9: MICRO ORGANISMS AROUND US

Group of micro organisms: Bacteria, Viruses some algae, some fungi and protozoa.
Identification of micro organisms: Organism: In air, pond water, river and streams.
