Answer 2

$\huge{ \boxed{ \red{ \mathcal{Xylem:}}}}$

1. Conducts water and mineral salts from the roots to the aerial parts of the plant.
2. Made up of tracheids, vessels, xylem prenchyma and xylem fibres.
3. Conducting (vessels and tracheids) cells are dead.
4. Conduction is unidirectional.
5. Conduction does not require any expenditure of energy.

$\huge{ \boxed{ \red{ \mathcal{Phloem:}}}}$

1. Translocates food from the leaves to the storage organs and growing parts of the plant.
2. Made up of sieve tubes, companion cells, phloem parenchyma and phloem fibres.
3. Conducting cells (sieve tubes) are living.
4. Conduction is bidirectional.
5. Conduction requires expenditure of energy.
