Integrated Science Test
Plants ch. 20-22
The test will consist of the following:
25 multiple choice
11 true/ false
8 analysis questions
** Note: You do not need to study ALL of ch. 20-22; rather, just study the parts that are
covered in the powerpoint presentation.**
1. What does xylem carry up a plant.
2. Annual vs. perennial
3. Tree rings (that tell a tree’s age) are produced by growing vascular cambium
4. Fibrous roots: monocot or dicot?
5. Taproots: monocot or dicots?
6. Examples of monocots and dicots
7. Structure of a leaf: blade and petiole
8. Primary growth (growth in length)- apical meristem
9. Secondary growth (growth in width)
10. Movement of phloem: Source to sink (pressure-flow hypothesis)
11. Movement of water: the “pusher” (root pressure) and the “puller” (transpiration)
a. Xylem moves water up a plant
b. Cohesion & adhesion of water move the water up
12. Definition of transpiration
13. Carnivorous plants, epiphytes, parasitic plants
14. Plant minerals (from the periodic table)
15. Guard cells and stomata (structure of, function of)
16. What does the mineral magnesium do for a plant?
17. A Venus flytrap is both a producer (photosynthesis) and a consumer (eats insects).
18. Hormones- definition
19. Plant hormones- auxins, cytokinins, gibberellins, abscicic acid, ethylene
20. Tropisms- definition
21. Definitions- gravitropism, phototropism, thigmotropism
22. Photosynthesis takes place in LEAVES.
23. 3 plant cell types- parenchyma, collenchyma, sclerenchyma
24. What are the 2 types of vascular tissue?
25. Stomata/ Guard cell structure/ function
