Fig. 1.1 shows a plant with a magnified transverse section (TS) of the root and an incomplete, magnified transverse section (TS) of the stem.
The transverse section of the root in Fig. 1.1 shows the distribution of xylem and phloem tissue.
Using a labelling line and the letter X, show, on Fig. 1.1, the location of the xylem tissue in the transverse section (TS) of the root.
Complete the transverse section (TS) of the stem in Fig. 1.1 to show the distribution of xylem and phloem tissue.
Using a label line and the letter P, show the location of the phloem tissue that you have drawn.
State the functions of phloem tissue.
