Botany Study Guide CH 24 Reproduction of Seed Plants

  1. In gymnosperms, OVULES are located near the base of each ______________.

  2. The sterile leaves of a flower are the ____________ & _________________.

  3. A pollen grain landing near an ovule produces a __________ _____________.

  4. In ANGIOSPERMS, the nucleus of each pollen grain undergoes ____ ______________ division(s).

  5. The ENDOSPERM of a corn seed develops through the process of _____________ fertilization.

  6. All fruits contain ___________ & help to disperse them; All fruits are formed from the _________ wall.

  7. A seed that is dispersed to an area far away from the parent plant might face less _________________.

  8. Seeds dispersed by animals typically are contained in fleshy nutritious fruits.

  9. A period during which the embryo of a seed is alive but not growing is _____________________.

  10. What is true of seed coat during germination? (what has to happen to the seed coat for germination to occur?)

  11. When a plant reproduces vegetatively, its offspring are gentetically ____________.

  12. The horizontal stems of a strawberry plant are called _______________.

  13. What would be the best method of propagating most woody plants?

  14. Which two methods of plant propagation are most similar?

Planting seeds & rooting cuttings

Rooting cuttings & grafting

Grafting & budding

Root cuttings & budding

15. In gymnosperms, ___________ _____________ produce male gametophytes.

16. In the gymnosperm seed, the _________ _______ ________ is part of the old sporophyte generation.

17. Be able to LABEL a FLOWER diagram like figure 24-5 page 612 and tell the function of each structure.

18. A coconut is a very large _______________ that contains a milky endosperm layer.

19. From a line graph of Annual Corn Yield in the United States, be able to read the graph and answer questions from it.

20. What is the function of a pollination drop?

21. Corn, sugar beets, cauliflower, & cabbage were all developed by _________________ breeding.

22. From a diagram of several seeds, be able to determine how each seed is most likely to be dispersed.

23. What role does water play in the germination of a seed?

24. From a diagram that shows the Life Cycle of A Typical Angiosperm (similar to figure 24-7 page 614)…be able to answer “using science skills” questions about the diagram. The structures will already be labeled. You will need to know which structures are “diploid”, which structure allows pollen to enter the ovary, how many nuclei are in the embryo sac, did the nuclei come from a haploid cell or a diploid cell & through what process were the nuclei formed, what does the zygote develop into, FROM THE DIAGRAM-what is the most likely way that pollen will disperse. **REMEMBER that the test diagram is NOT EXACTLY like the BOOK DIAGRAM…you must be able to APPLY!

25. ESSAY: Explain how a forest fire can affect the germination of certain PINE SEEDS, & what effect this has on the recovery of the forest from a fire.
