Plant Reproduction Study Guide
Required Reading: Capon book - Chapter 9 and pp 201-209, online notes
Goal of the Unit: The goal of this unit is to provide an introduction 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; (b) a mangrove tree that lives along the coast line of equatorial oceans; (e) corn. Hint: think about the stability of the habitats.
3. Sketch and label a typical flower. Indicate the function of each part (receptacle, sepals, petals, stamens, anther, filament, pistil, stigma, style, ovary, ovule, nectary. (a good question)
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? (another good question). Check out Gink & Go.
5. Can you make a concept map to the entire chapter? Or how about, just flower structure? or life cycle?
6. Compare and contrast self-pollination and cross-pollination.
7. What is a fruit? Compare and contrast simple, aggregate and multiple fruits.
8. Identify some of the ways in which plants disperse their fruits/seeds.
