Answer 2

Answer:

There are two types of vascular tissue. Phloem (FLOH um) is the vascular tissue through which food moves. When food is made in the plant's leaves, it enters the phloem and travels to the plant's stems and roots. Water and nutrients, on the other hand, travel in the vascular tissue called xylem (ZY lum). The plant's roots absorb water and nutrients from the soil. These materials enter the root's xylem and move upward into the plant's stems and leaves.
