Section 2: The Vascular System
Study Guide B
Key Concept
THE VASCULAR SYSTEM ALLOWS FOR THE TRANSPORT OF WATER, MINERALS, AND SUGARS.
Vocabulary
|COHESION-TENSION THEORY |TRANSPIRATION |PRESSURE-FLOW MODEL |
MAIN IDEA: WATER AND DISSOLVED MINERALS MOVE THROUGH XYLEM.
THE COHESION-TENSION THEORY PROPOSES THAT THE PHYSICAL PROPERTIES OF WATER ALLOW THE RISE OF WATER THROUGH A PLANT. SKETCH AND DESCRIBE COHESION AND ADHESION OF WATER MOLECULES.
Fill in the sequence diagram below to explain how water moves through the roots, stems, and leaves of a plant within xylem. Use the text and Figure 2.2 to help fill in the diagram.
Study Guide B continued
Main idea: Phloem carries sugars from photosynthesis throughout the plant.
6. PHLOEM SAP MOVES FROM A SUGAR SOURCE TO A SUGAR SINK. WHAT ARE TWO PLANT PARTS THAT MIGHT BE SOURCES OF SUGARS?
7. What is a sugar sink in a plant?
8. The pressure changes between sugar sources and sinks keeps sap flowing through phloem. Is there a higher concentration of sugars at a sugar source or a sugar sink?
9. In the movement of sap through phloem, what two events require energy on the part of the plant?
10. Water moves into the phloem due to the high sugar concentration there. It requires no energy. What is this process called?
Vocabulary Check
|cohesion-tension theory |pressure-flow model |transpiration |
_________________ 11. Well-supported theory that describes how sugars move through a plant within phloem
_________________ 12. Well-supported theory that describes how water and dissolved minerals move through a plant within xylem
_________________ 13. Term that describes how water moves through a plant within xylem by evaporation from leaves
Section 3: Roots and Stems
Study Guide B
Key Concept
ROOTS AND STEMS FORM THE SUPPORT SYSTEM OF VASCULAR PLANTS.
Vocabulary
|VASCULAR CYLINDER |MERISTEM |PRIMARY GROWTH |
|ROOT HAIR |FIBROUS ROOT |SECONDARY GROWTH |
|ROOT CAP |TAPROOT | |
MAIN IDEA: ROOTS ANCHOR PLANTS AND ABSORB MINERAL NUTRIENTS FROM SOIL.
IN THE SPACE PROVIDED, SKETCH A ROOT TIP. DRAW LINES FROM THE TERMS TO LABEL THE SKETCH, AND DESCRIBE THE FUNCTION FOR EACH OF THE PARTS. USE FIGURE 3.1 AND THE TEXT TO FILL IN THE DIAGRAM.
4. How do root hairs help a plant?
5. What are root systems made of fine, similarly sized branches called?
6. What are root systems that have one main root and can sometimes store food called?
7. Plants are not just soaking up water. They use energy to absorb ___________________.
8. The increased concentration of ions in root cells causes ___________________ to move into the root.
Study Guide B continued
9. An example of a mineral needed in large amounts is ___________________.
10. Other minerals, such as ___________________, are needed in small amounts.
Main Idea: Stems support plants, transport materials, and provide storage.
11. WHAT ARE THREE FUNCTIONS OF MOST STEMS?
12. Look at Figure 3.4. What are two plants whose stems store water?
13. What special adaptation do strawberry plant stems have?
14. What are two stems that grow underground?
15. What are four characteristics of herbaceous stems?
16. What is growth that makes stems grow taller or roots grow longer called?
17. What is growth that makes stems and roots of woody plants grow wider called?
18. What represents one year of growth on a tree ring?
Vocabulary Check
_________________ 19. Tough covering on root tip
_________________ 20. Unspecialized tissue of dividing cells
_________________ 21. Houses xylem and phloem
_________________ 22. Root system made of equal-sized roots
_________________ 23. Growth pattern that increases height and length
_________________ 24. Increases surface area of a root
_________________ 25. Root system that reaches deep into the ground
_________________ 26. Growth pattern that increases width
Section 4: Leaves
Study Guide B
Key Concept
LEAVES ABSORB LIGHT AND CARRY OUT PHOTOSYNTHESIS.
Vocabulary
|BLADE |MESOPHYLL |
|PETIOLE |GUARD CELL |
MAIN IDEA: MOST LEAVES SHARE SIMILAR STRUCTURES.
1. SKETCH A LEAF ATTACHED TO A STEM. LABEL THE BLADE, PETIOLE, STEM, AND
AXILLARY BUD.
Use a sequence diagram to fill in the steps describing how stomata regulate
gas exchange.
Study Guide B continued
2. What are three leaf characteristics that can be used for plant identification?
3. How can you tell the difference between a leaf and a leaflet?
Main Idea: Most leaves are specialized systems for photosynthesis.
4. WHAT IS THE PHOTOSYNTHETIC TISSUE OF A LEAF?
5. How are the two types of mesophyll found in a leaf specialized for photosynthesis?
6. What are three adaptations of plants that help reduce water loss in a desert or cold environment?
7. Use the following terms and stack them like you were building a sandwich in the order they are found within a leaf: mesophyll, dermal tissue, dermal tissue, cuticle, cuticle.
