1. Believe it or not, the development of seeds was a major step in the evolution of plants. First to develop were 'naked' seeds (not surrounded by fruit), which can be found among the conifers and other plants of what taxonomic division? liverwort angiosperms gymnosperms bryophytes

2. The next big advance, seedwise, was the evolution of flowering plants which surround their seeds with lovely nutritious tissue (aka fruit). To what division do these plants belong? gymnosperms liverwort bryophytes angiosperms

3. Well, seeds are very nice, but you still have to have two parents. In plants, the parents are haploid gametophytes (the male gametophyte is often contained in a grain of pollen), and they produce a diploid sporophyte, which in turn produces gametophytes of both genders. What is this pattern called? the Krebs Alternation Krebs Cycle Calvin Cycle alternation of generations

4. In flowering plants, the zygote is the product of an event called 'double fertilization': every cell in the zygote is descended from one triploid cell, called what? triploidon apple gametophyte endosperm

5. Flowering seed plants are often divided into two groups: monocotyledons and dicotyledons. What does 'cotyledon' mean? fruit seed leaf vein structure (on surface of leaf) supporting root

6. The earliest known seed plant, Elkinsia polymorpha, appeared in what geologic time period? Mesozoic Devonian Cenozoic Cretaceous

7. An unfertilized seed is partially surrounded by an integument (or protective layer). The hole in the integument is what pollen enters through; what is this opening called? drilone endosperm micropyle gametophyte

8. What is the process in which a seed begins to grow into a plant? dormancy budding birth germination

9. The integument, or protective layer surrounding a seed, is also known by which of these less scientific-sounding names? seed pod skin seed coat seed armor

10. Seed plants evolved in the oceans and only later made the transition to land. True False
