Transpiration — practice question

A student carried out an investigation into transpiration from leaves. She selected leaves from the same plant that were similar in size. She measured their mass and then put them under different conditions. While the leaves transpired, their mass decreased.
(a(i))[1]

Fill in the table by working out the change in mass for leaf K.

(a(ii))[2]

Complete the table by finding the percentage change in mass for leaf J. Show your working. Give your answer to one decimal place.

(b)[1]

State which conditions led to the greatest transpiration in the leaves.

(c(i))[1]

Describe how tissue O is adapted for its role.

(c(ii))[3]

Complete the flow chart by arranging the letters of cells M, N, O and P in the right order, beginning with water absorption and finishing with transpiration from the leaf.

(d(i))[1]

State the name of the tissue type that carries water up the stem.

(d(ii))[1]
