KNOWLEDGE of SUBJECT MATTER:

  1. define key terms used in this unit

  2. list the resources required for normal growth and reproduction

  3. describe and illustrate the structural organisation of a monocotyledon and dicotyledon

  4. contrast the role of diffusion and osmosis including active transport as essential to plant requirements

  5. understand root structure including tissue specialisation

  6. explain the structure and function of the xylem and phloem for movement of materials

  7. identify and explain the role of stem tissues

  8. explain the leaf structures and mechanisms that regulate the exchange of gases

  9. trace the movement of water by leaf transpiration through the plant

  10. know the effect on growth, flowering and fruiting of plant hormones (e.g. gibberellins, auxin, cytokinins, ABA)

  11. understand the effects of environmental factors on growth, fruiting and flowering

  12. list and describe the structures of the digestive system and relate them to their functions

  13. describe what happens at each stage of digestion

  14. explain the factors that determine the efficiency of diffusion

  15. distinguish between cellular respiration and breathing

  16. describe the structure and function of the human gas exchange system in humans

  17. describe the processes involved in the excretory systems in animals

  18. draw and label diagrams of the kidneys

  19. list and describe the structures in the kidneys

  20. describe the function of nephrons including filtration, reabsorption and its effect on the composition of urine
  21. draw and label diagrams of the heart and describe the function of each structure

  22. list and describe the function of the structures of the circulatory system

  23. relate the structure of the heart, arteries, veins, capillaries and lymphatic vessels to their function in the human body

  24. distinguish between lymphatic and blood circulation

  25. describe the process of active transport in various systems within human body systems



 


SIMPLE SCIENTIFIC PROCESSES:
  1. suggest consequences of lack of adequate water, light or minerals to a plant

  2. apply the principles of osmosis, diffusion and active transport in a given situation

  3. identify cell types in stems, roots and leaves from experimental results

  4. present research on the role of tissue culture in plant propagation

  5. construct graphs with experimental data of water movement through a plant

  6. predict plant adaptations for specific environmental conditions

  7. develop and test hypotheses related to digestive processes

  8. infer the functions of digestive organs from observations of their structure

  9. distinguish between fact and opinion in dietary claims
  10. predict the effects on ventilation and heart rates with changes in activity

  11. compare and contrast the requirements for gas exchange in aquatic and terrestrial environments

  12. interpret data related to the functions of the kidneys, skin and lungs

  13. infer the function of organs of excretion from observations of their structure


COMPLEX REASONING PROCESSES:
  1. critically examine data relating to the effects of changing environmental conditions on adaptations/changes in plant structures

  2. critically examine the effect of human endeavour in plant industries, such as tissue culture

  3. predict the consequences of continued increases in global carbon dioxide levels on plant species

  4. design an investigation of the effect of salinity (or some other environmental factor) on particular plant growth

  5. solve problems related to the anatomy and physiology of animals, and their ability to overcome environmental conditions

  6. interpret, analyse and evaluate data relating to experiments involving the digestive, circulatory, excretory and respiratory systems

  7. examine the consequences of organ transplants for the body
