The Figure shows two types of transport tissue, P and Q, from the stem of a plant.
Figure

Identify which tissue, P or Q, is xylem.
Give a reason for your answer using the Figure.
Explain how lignin in the walls of xylem helps xylem to transport water.
Phloem is made of living cells.
Explain why living cells are needed for phloem to transport sucrose.
Name the process by which sucrose is transported around a plant.
