1All plants have xylem and phloem. Yes No Do you agree with the statement?

2Xylem carries sugar from the leaves to the other parts of the plant. Yes No Do you agree with the statement?

3Woody stems have more xylem than soft stems. Yes No Do you agree with the statement?

4Two types of root systems are the taproot and the fibrous. Yes No Do you agree with the statement?

Stems Xylem and Phloem Kinds of Stems Leaves grow on stems, which are a plants organ and hold the leaves high so that they get more sunlight. Xylem tissues are tubes that carry water and minerals from the roots to the rest of the plant. Phloem tissues are tubes that carry sugar from the leaves to the rest of the plant. Dead phloem make up the bark from a tree. Woody stems have lots of xylem tissue like trees and shrubs. Soft stems have less xylem tissue like tulips and pea plants. First paragraph pg. 98 Fourth paragraph pg. 98

Roots Functions of Roots Roots are also plant organs that grow in the ground, are strong, hold the plant in place and allow the plant to get water from the ground. A taproot is large, grows straight down and stores food for the plant. Some examples are carrots, beats and turnips. A fibrous root system has many roots that grow in all directions and get smaller and smaller as they grow out. Roots hold a plant in place and may store food. Roots also take in water and minerals from the soil through the root hairs to help the plant grow, reproduce and repair itself. First paragraph pg. 100 First paragraph pg. 101
