Questions | Answers
 

1. Annual (< 1 year), Biennial (2 years), Perennial (> 2 years)

2. Grasses, Forbs, Succulents, Shrubs, Trees

3. A plant that stores water in its tissues - root, stem, leaf

4. Flower

5. A) Petals (attract pollinators), B) Stigma (accepts the pollen), C) Style (holds the stigma up to increase chance of pollination), D) Ovary (produces the eggs, polar nuclei, seeds), E) Sepals (protect flower bud), F) Filament (holds the anther up increase chance of pollination), and G) Anther (produces the sperm/pollen). Note that the Stamen is the male part and is composed of the anther and filament and the pistil is the female part and is composed of the stigma, style, and ovary.

6. Perfect (have functioning stamens and pistil), Imperfect (have either functioning stamens or pistil, but not both).

7. Monoecious (male and female flowers on same plant); Dioecious (male and female flowers on separate plants).

8. Expanded leaf base, petiole, and blade. See diagram in PowerPoint for how to draw a simple leaf and label the 3 parts.

9. Simple (single, undivided blade), Palmately compound (blade divided into leaflets that radiate from single point), Pinnately compound (blade divided into leaflets that come out from both sides along a rachis), Bipinnately compound (blade divided into primary and secondary leaflets along a rachis). Be able to draw each type.

10. Entire (smooth-edged), toothed, lobed

11. Alternate, Opposite, Whorled

12. Germination, Growth, Reproduction, Death

13. Photoperiod, temperature, moisture, light, abrasion, fire, digestive enzymes

14. Asexual cloning; Sexual reproduction

15. Gamete production, Pollination, Double Fertilization, Seed Production, Seed Dispersal

16. Sperm are produced in anthers and eggs are produced in the ovary

17. The transfer of pollen from anther to stigma.

18. Wind, water, and animals

19. The two sperm from the pollen grain travels down the style into the ovary. One sperm fertilizes the egg and produces the embryo which develops into the new plant. The other sperm fertilizes the two polar nuclei and produces the endosperm which feeds the embryo. The embryo and endosperm are packaged into a seed.
