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? angiosperms gymnosperms bryophytes liverwort

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 angiosperms bryophytes liverwort

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? Krebs Cycle the Krebs Alternation alternation of generations Calvin Cycle

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? endosperm gametophyte triploidon apple

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

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

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

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

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