Transpiration — practice question

Fig. 5.1 illustrates some apparatus used to investigate transpiration. The transpiration rate can be worked out by measuring the distance travelled by the meniscus in five minutes.
(a)[1]

Name the tissue in a plant that carries water from the roots to the leaves.

(b(i))[1]

State one conclusion that can be made from the results in Table 5.1 about how temperature affects the rate of transpiration.

(b(ii))[2]

Suggest why the experiment was not continued at temperatures above 50^{\circ}C.

(c(i))[1]

Predict how these results would differ from the results shown in Table 5.1.

(c(ii))[2]

Give two reasons why the results would be different.

(d)[1]

State one factor, other than temperature, that can affect the rate of transpiration.
