Answers:

1. C – Trees grow in height at places called primary meristems, which are located at the tips of the shoots.  

2. C – Mycorrhizae is the name given to the symbiotic relationship between fungus and tree roots. 

3. B – Topping a tree removes the apical meristem, and increases the chances that the tree will die. 

4. A – Meristems are areas of rapid cell division. Primary (apical) meristems are located at the shoot tips, while secondary (lateral) meristems are located around the circumference of the trunk. 

5. D – Transpiration is the pumping of water from the ground, to the top of the tree and out the leaves, into the air. 

6. D – Any of these characteristics may signal that a given tree is hazardous. 

7. C – Many fire-adapted pines only release their seeds after ground fires have cleared the earth. 

8. C – Mulching reduces evaporation, moderates temperature and releases nutrients into the soil. 

9. A – Coastal redwoods (Sequoia sempervirens) are the tallest trees, whereas giant sequoias (Sequoiadendron giganteum) are the most massive. 

10. D – Deciduous trees shed their leaves regularly, while evergreen trees are always green.
