Question

What are the 2 kinds of vascular tissue, and what do they do?

Answer 1

xylem and phloem

These two types of vessels run side-by-side, extending from roots to leaves. They provide channels for the transport of water and nutrients.

Xylem transports water upward from the roots. Tracheids and vessel elements are the components and both are thick-walled cells which are dead at maturity. Elongated tracheids with tapered ends are connected by pits in their walls. Adjacent vessel elements lack separating cell walls and are stacked in columns forming continuous tubes called vessels.

  Phloem transports dissolved carbohydrates, hormones, and ions. The conducting cells are sieve tube members (or cells) with cytoplasm but no nuclei. Adjacent conducting cells are connected by clusters of pores called sieve plates. Neighboring companion cells connect with sieve tube members (cells) and their nuclei control both cells.
