#PAG1
Investigate a factor affecting the initial rate of an enzyme controlled reaction.
#PAG2
Use of the light microscope, including simple stage and eyepiece micrometers and drawing small numbers of cells from a specialised tissue.
#PAG3
Make a temporary squash preparation of a root tip to show stages of mitosis in the meristem under the light microscope.
#PAG4
Investigate the effect of sucrose concentrations on pollen tube growth.
#PAG5
Investigate the effect of temperature on beetroot membrane permeability.
#PAG6
Determine the water potential of plant cells.
Water potential = turgor pressure + osmotic potential
\(ψ = P + π\)
#PAG7
Dissect an insect to show the structure of the gas exchange system.
#PAG8
Investigate factors affecting water uptake by plant shoots using a potometer.
#PAG9
Investigate factors affecting the rate of respiration using a respirometer.
#PAG10
Investigate the effects of different wavelengths of light on the rate of photosynthesis.
#PAG11
Investigate the presence of different chloroplast pigments using chromatography.
#PAG12
Investigate the rate of growth of bacteria in liquid culture.
#PAG13
Isolate individual species from a mixed culture of bacteria using streak plating.
#PAG14
Investigate the effect of gibberellin on the production of amylase in germinating cereals using a starch agar assay.
#PAG15
Investigate the effect of different sampling methods on estimates of the size of a population.
#PAG16
Investigate the effect of one abiotic factor on the distribution or morphology of one species.
