Integrative
Biology 102:
Lecture Outline
Plants Used to Feed the World
Lecture Objectives:
By the
end of the lecture (and after some
work with the text), you should be able to:
- identify where energy is stored in seeds, stems and roots.
- explain how artificial selection has changed the characteristics
of domesticated plants.
- draw and label a diagram of a monocot seed and a eudicot seed.
- give the function of each of the parts of a seed.
- describe the growth sequence in a
germinating seed.
- explain why seeds are good sources of
nutrition.
- list the four plants most eaten by the world population.
- describe the types of environment where wheat, maize, rice,
cassava, and millet are
grown.
- explain "center of origin" and list the centers of origin for
each of the plants covered in the lecture.
- explain what the "doomsday
vault" is and why it is important for future food security.
- identify which part of each plant is eaten.

in lecture:
- What is unique about meiosis?
- What is the significance of meiosis in the plant life cycle?
- What are the products of meiosis, and where do they occur in
flowering plants?
