This programme looks as two naturally occurring phenomena that are essential to the survival of plants, light and water. It covers photosynthesis and cellular respiration, and compares the products and reactants, and other characteristics of each process. The vital role of water in plants is explored, including the movement of water into a plant through its roots, transportation and translocation of water and nutrients inside a plant, and the ultimate release of water vapour into the atmosphere, or transpiration. It explains the function of vascular tissues, or xylem and phloem, and their importance in moving various substances around a plant. The junior programme covers the material at a more general and simplistic level, which is suitable for lower/middle secondary levels. The senior programme covers the material in more complex terms, and is pitched at students of senior biology. Show Less

This programme examines the form and functioning of plants. It looks at the characteristics of all living things, including cellular respiration, photosynthesis, growing and repairing, responding to stimuli, taking nutrients from the environment, and reproduction – and emphasises how these occur in plants.

Evolution is the gradual change that can be seen in a population’s genetic composition, from one generation to the next. The three main mechanisms of evolution include genetic drift, mutation and natural selection. The first part concentrates on Genetic Drift with the use of a model to demonstrate its effect on small and large populations. An example will also be used to explain how Genetic Drfit can lead to the formation of a new biological species over a long period of time. Then models of Mutation and Natural Selection are demonstrated and the results carefully tabulated and analysed. Examples of particular populations, which have likely evolved through each mechanism, are also highlighted. Show Less

This programme is an introduction to botany for senior secondary students. It explores the remarkable world of plants - without them, no other life form would exist. It looks at characteristics of all living things, including cellular respiration, growing and repairing, responding to stimuli, taking nutrients from the environment, and reproduction - and emphasises how these occur in plants. Both sexual and asexual reproduction are covered ad the role of chlorophyll, chloroplasts and sunlight is highlighted. The programme also explores the form and vital functions of roots, stems and leaves. Show Less
