FREC 2314 EXAM 2 QUESTIONS WITH CORRECT ANSWERS
2025/2026 RATED A+
1. Monoecious -"one house"
-has male and female flowers on same tree
-majority of trees
2. Dioecious -"two houses"
-has only male or female on one tree
-ex: boxelder, willow, persimmon, holly, and ginkgo
3. Complete Flower -has all flower parts
-corolla
-sepals
-pistil
-stamen
4. Incomplete Flower -missing one or more of the parts
5. Perfect Flower -functioning male and female parts
-only requires stamen and pistils
-can be complete or incomplete
6. Imperfect Flower -always lack either pistil or stamen
-will always be incomplete
7. Staminate -flowers that only have a stamen
8. Pistilate -flowers that only have a pistil
9. How Long Does It Take For -generally 10-20 years
Reproduction To Began? -apple trees can in 3 with right conditions
10. Structure of Monoecious -typically stamen is at the bottom
Trees -pistil above
-do this so inbreeding doesn't occur

11. Polygamodioecious -can have imperfect female or male
-can change male/female each year
ex: red maple, ash
12. Fruit (angiosperm) -develop from flowers
-majority of angiosperm develop in one growing season
-flower in april/may...sep/oct/nov see fruit
-exception is red oak
13. Fruit (gymnosperm) -most gymnosperms have one growing season
-ex: furs, conifers, spruces
-exception pines (they have 2)
14. Mycorrhizae -fungal root, always present
-symbiotic mutualism
-fungus infects root system
-fungi gets increased sugars and tree gets more surface area for
root system
15. Endotrophic -not visible w naked eye
-use microscope
-ex: maple, poplar
16. Ectotrophic -visible
-phosphorous uptake
-ex: pines, birch, oaks, and hickories)
17. Nodules -N-fixation
-N2->NH3
18. Rules of Thumb for Predict- -good seed years not the same for all species
ing Seedling -production for a species varies between areas year to year
-Rare for all species in area to have a good/bad seed year at the

same time
-Some individual trees are good seed producers
-Good seed years can not be predicted until flower buds are
formed
19. Label the Parts of a Seed
20. Seed Dormancy -delayed germination
-prevents the seed from germination during bad environmental
conditions
21. Seed Coat Dormancy -results from seed coat that is impermeable to water/oxygen
-ex: black locust seed
22. Embryo Dormancy -immature embryo
-requires "afterripening"
23. Inhibitors -chemical inhibitors
-ex: abscisic acid
-ex: red oak seed coat
24. Seed Coat Scarification -put seeds in strong nitric acid for 15 mins
-take out seeds and they come up (more common method)
-put them in scarifier and tumbles with abrasive material
-mechanically scratches the seed coat
25. Cold-Moist Stratification -2 degrees C for 30-90 days
-can be completed in a refrigerator or winter conditions
-ex: red oaks/pines/buried walnut seeds
