Cambridge IGCSE Biology 0610 · 2026–2028 v3 · Original learning materials.
Transpiration as the loss of water vapour from leaves (8.3.1); evaporation from the surfaces of the mesophyll cells into the air spaces and diffusion out through the stomata (8.3.2); investigating the effects of temperature and wind speed (8.3.3); the internal surface area and the size and number of stomata (Supplement 8.3.4); the transpiration pull (Supplement 8.3.5); the effects of temperature, wind speed and humidity explained (Supplement 8.3.6); wilting (Supplement 8.3.7). The distances in the experiment come from a teaching model.
Apparatus, amounts and times in the experiment are illustrative. Real practical work follows a teacher-approved safety method.
