PLANT REPRODUCTION STUDY GUIDE
Required Reading: Purves, Chapter 38; and pages 489 - 490, 501 -503, 515 -518, and 521 - 528
Goal of the Unit: The goal of this unit is to provide an introduction to the reproductive biology of the flowering plants.
Objectives: Upon completion of this unit you should be able to:
Important Terms/Concepts: Can you use the following terms/concepts in a conversation?
Some additional questions and study tips:
1. For each of the following, circle the one that doesn't belong to the group. Then, explain the relationship between the remaining members by giving a title to the group: (a) anther, egg, ovule, placenta, stigma; (b) leaf, ovary, petal, root, sperm; (c) coleoptile, endosperm, epicotyl, hypocotyl, radicle; (d) corn, peanut, pumpkin, spinach, tomato.
2. Some plants produce viviparous seeds/embryos. This means that the embryos never undergo a dormancy process and continue to develop right on the parent plant. Which of the following do you think is most likely to have viviparous embryos: (a) oak trees that live in CSB/SJU woods or (b) a mangrove tree that lives along the coast line of equatorial oceans.
3. Sketch and label a typical flower. Indicate the function of each part. From where did flowers originate?
4. Sketch out the typical life cycle of a flowering plant. Include the following in your diagram: sporophyte, microspore, megaspore, gamete, sperm, egg, fertilization, meiosis, gametophyte, male gametophyte, female gametophyte, microspore mother cell, megaspore mother cell, zygote, embryo, haploid, diploid. Do you know in which part of the plant the various stages occur?
5. Can you make a concept map to the entire chapter? Or how about, just flower structure? or life cycle?
6. Make an audio cassette tape defining all of the key terms given at the end of the chapter. Then, use each term in a sentence. Or just write out the definitions. Then repeat them to a friend.
Fruits vs. Veggies
Bonus Question (1 point)
- submit answer to me no later than Study Day
On a trip to the supermarket or garden store, did you ever notice that you can buy seeds for Seedless Watermelons? If the watermelons that grow from these seeds are truly seedless (which they are!), then where do the seeds for growing seedless watermelons come from?
