1
What are the functions of the shoot system and the root system in a plant?
A)Water and minerals are transported through a plant’s shoot system; a plant’s root system supports the plant.
B)The shoot system transports sap; the root system transports water and minerals.
C)The shoot system transports sap; the root system is responsible for photosynthesis.
D)The shoot system transports the sap. The root system takes in water and minerals and uses them for photosynthesis.
2
Which part of the plant is not included in the shoot system?
A)root
B)stem
C)leaves
D)fruit with seeds inside
3
What function is performed by phloem tissue?
A)Phloem tissue helps move water and minerals from the roots to other parts of the plant.
B)Phloem tissue helps transport materials needed for photosynthesis to the leaves of the plant.
C)Phloem tissue helps move sugar to other parts of the plant after the process of photosynthesis.
D)Phloem tissue helps move sugar to various parts of the plant so that photosynthesis can begin.
4
What action causes water movement through the plant in the xylem tissue?
A)a push from the roots and a push from the leaves
B)a pull from the roots and a pull from the leaves
C)a push from the roots and a pull from the leaves
D)a pull from the roots and a push from the leaves
5
What is the difference between sucrose and starch?
A)Sucrose can be chemically changed into starch, but starch cannot be chemically changed into sucrose.
B)Starch is soluble in water; sucrose must be broken down before it is soluble in water.
C)Starch is a type of sugar that combines with glucose to become sucrose.
D)Starch cannot travel through the plant stem because it is not soluble in water. Sucrose is soluble in water.
6
Which statement best describes how nutrients are produced and moved through the plant?
A)Photosynthesis produces sucrose, which combines with other molecules to create a type of sugar called glucose. Glucose makes its way through the stem to the roots and is chemically changed into starch and stored.
B)Photosynthesis produces glucose, which is combined with other molecules to produce sucrose. Sucrose travels to the roots, changes chemically into starch, and is stored.
C)Photosynthesis produces glucose, which is combined with other types of sugar to produce starch. Starch is transported through the stem to the roots and chemically changed into sucrose and stored.
D)Photosynthesis produces starch, which is chemically broken down and changed into a type of sugar called glucose. The sugar makes its way to the bottom of the stem, where it combines with other molecules to form sucrose in the roots.
