Chapter 39 Study Guide Plant Reproduction Learning Objectives To become familiar with the floral organs involved in reproduction To understand the process of pollination and fertilization in flowering plants angiosperm and relate it to the plant s overall life cycle To understand how seeds and fruit are produced and the variations in seed and fruit types To understand seed embryo development and germination patterns I Be able to draw a generalized flower and all of the important structures a Describe the function and be able to label the main organs of a flower b Male organs i Stamen and all its parts 1 Anther consisting usually of two lobes each containing two sacs in which the pollen matures 2 Filament stalk of stamen c Female organs i Carpel and all its parts 1 Style 2 Ovary 3 Ovule d Make sure to understand the components of an ovary e Know that there are variations in the male and female structures f Know the different types of fruit i Simple fruit Pea ii Aggregate fruit Raspberry fruit iii Multiple fruit Pineapple fruit 1 Know from where fruit develops 2 Know what seeds are and how they define a fruit 3 Be able to identify the parts of the plant which make up fruits and those which make up vegetables 1 Chapter 39 II III IV V Study Guide Know the difference between monoecious and dioecious and give an example of each a Monoecious carpels and stamens in one plant Ex corn b Dioecious carpels and stamens in separate plants Be able to explain and label a plant life cycle illustrating alternation of generations Be able to explain why it is called alternation of generations a Know the stages that are haploid vs diploid b Know where mitosis meiosis occurs and fertilization c Know what the multicellular structures are and their functions i Sporophyte diploid ii Male and female gametophytes haploid Explain the process of pollination and double fertilization step by step Be able to label all key structures of this process 2 Chapter 39 Study Guide a Know the role of the male gametophyte and all its components i Explain what is meant by pollen germination ii Be able to label a pollen grain 3 Chapter 39 Study Guide b Know the role of the female gametophyte and all its components i Label the egg and polar nuclei ii Antipodal cells and synergids 1 How do we get all of these cells nuclei c Describe the outcome of double fertilization i What are the most important structures in embryo development Know what each is and its function 1 seed leaves cotyledons 2 suspensor cells 3 proembryo a know parts of the proembryo different tissues i protoderm ground meristem procambium 4 endosperm ii Why are fruits important think seed dispersal iii What are the differences between seeds with one and two cotyledons 1 overall structure 2 germination 3 what is the difference between epi and hypocotyls 4 what is a radicle d What are some environmental cues for germination to occur Note Be familiar with all figures on the outline PPT presentation 4
