Complete the sentences to describe the results shown in Figure 2.2. The rate of water uptake at 40 cm was 2.60 mm 3 per minute. The rate of water uptake at 80 cm was mm 3 per minute. The difference in rate of water uptake between 40 cm and 80 cm was mm 3 per minute. The student concluded that an increase in the wind sp...

Complete the sentences about transpiration. Transpiration is the loss of water vapour from leaves. Water evaporates from the surfaces of the cells into the spaces. Water vapour moves out of the leaves through the

The list shows six conclusions. As temperature increases, the distance moved by the air bubble decreases. As temperature increases, the rate of transpiration decreases. As temperature increases, the rate of transpiration increases and then remains constant. From 20 °C to 30 °C, the rate of transpiration triples. From 2...

What examiners said
Comprehensive responses • Most candidates described suitable variables that they would keep the same during their investigation. • Candidates also described appropriate methods to change wind speed, with the use of a fan being the most common. Some candidates described using the fan set at different speeds while others described placing the fan at different distances from the plant. Both were suit...

Some candidates correctly completed the sentence about transpiration, but many stated that water evaporates from the surfaces of plant cells rather than from the surface of mesophyll cells.
— Examiner report, May/June 2023, 0610/43 Q2(a) (Cambridge)
Almost all candidates described the results in Fig. 2.1, but far fewer candidates attempted to explain the data. Some candidates who attempted to quote comparative data did not gain credit because they did not include both mass and wind speed in their answers. The explanations seen included the opening of stomata and the idea that energy from light increases the kinetic energy of water molecules.
