Lecture Objectives

At the end of this lecture (and after studying the text), you should be able to:

1. indicate the location and sequence of events of the general sexual life cycle of plants in flowering plant fertilization, fruit and seed development.
2. describe the double-fertilization of plants.
3. dissect a simple fruit and list the flower parts from which the fruit and seed structures developed.
4. list and explain the functions of the fruit.
5. describe the fruit ripening process and its connection to co-evolution with dispersers.
6. give examples of commercial applications of the use of plant hormones in the fruit industry.
