Standard:
2e Students know how sugar, water, and minerals are transported in a vascular plant.
Holistic Rating: Moderate coverage of this standard.
Pages A16-A23 provide moderate coverage of this standard. Pages A86-A87, D21-D22, and E11 provide very limited revisiting of these concepts in different contexts.
The standard does not specify the terms "xylem" and phloem" for the different classes of tubes in vascular plants. The Framework includes these terms as does the text. |
Aspects that help student learning:
Illustrations on pages A16-A18 explain and depict transport in vascular plants.
Aspects that do not help student learning:
There is a great deal of extraneous information. The illustration on page A18 does not include arrows showing the directions of movement in the xylem and phloem. The diagram on page A17 does not show that sugars and starches are transported into the root through the phloem.
Text does not use the term "vascular" that is in the standard. Comparing vascular and nonvascular plants (e.g., liverworts and mosses) would help students better understand the role of the xylem and phloem, and how they enable vascular plants to grow much taller than nonvascular plants.
Describing how sugar gets from the leaves to the roots (carrots, sweet potatoes), fruit (apples, bananas) and stalk (celery) that we eat would help students understand the role of the phloem.
