Movement is substances in xylem is unidirectional while in phloem it is bidirectional. Explain.

Explain why xylem transport is unidirectional and phloem transport bi-directional.

Explain phloem and its types in detail.

Differentiate between Xylem functioning and Phloem functioning.

Why are some substances are conductors while others are insulators?
