29 slides covering Photosynthesis
By the end of the powerpoint students would have covered:
4.4.1.1 Photosynthetic reaction
Photosynthesis is represented by the equation:
carbon dioxide + water light glucose + oxygen
Students should recognise the chemical symbols: CO2, H2O, O2 and C6H12O6.
Students should be able to describe photosynthesis as an endothermic reaction in which energy is transferred from the environment to the chloroplasts by light.
4.4.1.2 Rate of photosynthesis
Students should be able to explain the effects of temperature, light intensity, carbon dioxide concentration, and the amount of chlorophyll on the rate of photosynthesis.
Students should be able to:
measure and calculate rates of photosynthesis
extract and interpret graphs of photosynthesis rate involving one limiting factor
plot and draw appropriate graphs selecting appropriate scale for axes
translate information between graphical and numeric form.
(HT only) These factors interact and any one of them may be the factor that limits photosynthesis.
(HT only) Students should be able to explain graphs of photosynthesis rate involving two or three factors and decide which is the limiting factor.
(HT only) Students should understand and use inverse proportion – the inverse square law and light intensity in the context of photosynthesis.
(HT only) Limiting factors are important in the economics of enhancing the conditions in greenhouses to gain the maximum rate of photosynthesis while still maintaining profit.
**Required practical activity 6: investigate the effect of light intensity on the rate of photosynthesis using an aquatic organism such as pondweed. **
4.4.1.3 Uses of glucose from photosynthesis
The glucose produced in photosynthesis may be:
used for respiration
converted into insoluble starch for storage
used to produce fat or oil for storage
used to produce cellulose, which strengthens the cell wall
used to produce amino acids for protein synthesis.
To produce proteins, plants also use nitrate ions that are absorbed from the

24 slides covering Discovery and development of drugs
By the end of the powerpoint students would have covered:
Students should be able to describe the process of discovery and development of potential new medicines, including preclinical and clinical testing.
Traditionally drugs were extracted from plants and microorganisms.
• The heart drug digitalis originates from foxgloves.
• The painkiller aspirin originates from willow.
• Penicillin was discovered by Alexander Fleming from the Penicillium mould.
Most new drugs are synthesised by chemists in the pharmaceutical industry. However, the starting point may still be a chemical extracted from a plant.
New medical drugs have to be tested and trialled before being used to check that they are safe and effective.
New drugs are extensively tested for toxicity, efficacy and dose.
Preclinical testing is done in a laboratory using cells, tissues and live animals.
Clinical trials use healthy volunteers and patients.
• Very low doses of the drug are given at the start of the clinical trial.
• If the drug is found to be safe, further clinical trials are carried out to find the optimum dose for the drug.
• In double blind trials, some patients are given a placebo.

17 slides covering Cell division (chromosomes, mitosis and the cell cycle)
By the end of the powerpoint students would have covered:
4.1.2.1 Chromosomes
The nucleus of a cell contains chromosomes made of DNA molecules. Each chromosome carries a large number of genes.
In body cells the chromosomes are normally found in pairs.
**4.1.2.2 Mitosis and the cell cycle **
Cells divide in a series of stages called the cell cycle. Students should be able to describe the stages of the cell cycle, including mitosis.
During the cell cycle the genetic material is doubled and then divided into two identical cells.
Before a cell can divide it needs to grow and increase the number of sub-cellular structures such as ribosomes and mitochondria. The DNA replicates to form two copies of each chromosome.
In mitosis one set of chromosomes is pulled to each end of the cell and the nucleus divides.
Finally the cytoplasm and cell membranes divide to form two identical cells.
Students need to understand the three overall stages of the cell cycle but do not need to know the different phases of the mitosis stage.
Cell division by mitosis is important in the growth and development of multicellular organisms.
Students should be able to recognise and describe situations in given contexts where mitosis is occurring.
