Seed plant comparison Classify each label as a characteristic of, or a taxon belonging to the gymnosperms, eudicots, and/or monocots. Labels may be used more than once. Cycads Seeds develop inside ovary following fertilization Orchid Produce both seeds and pollen Species such as com whose pollen grains have only one spore Gnetophytes and ginkgo Conifers Embryos develop two cotyledons Oak trees Angiosperm (monocot) Angiosperm (eudicot) Gymnosperm

Describe (in words), the life cycle of an Angiosperm starting with a seed that is germinating right now, following that seedling though its life until it produces a seed of its own that will complete one full generation. Be sure to explain the steps involved in this plant’s life cycle related to its alternation of generations. Describe the reproductive structures produced along the way, using proper terminology that we have repeatedly discussed in the context of plant life cycles. Be...

Questions to complete: 1. How do the life cycles vary among the different plant groups? Gymnosperm vs. Angiosperm. 2. In comparison to mosses and ferns, what adaptations do gymnosperms have that make them better adapted to a dry environment? 3. Why are angiosperms so successful? 4. Compare and contrast a pinecone and a flower in terms of structure and function. 5. Describe flower morphology. 6. Explain why plant diversity can be considered a nonrenewable resource.

Question 24 3 pts The seeds of orchids (an angiosperm) are among the smallest known, with virtually no endosperm. What is therefore likely to be true? There is no fruit surrounding the seed. O Double fertilization does not occur in this species. Orchids are not true flowering plants. The developing plant quickly obtains nutrition through photosynthesis or other means. o Orchid pollen grains are unusually large.

UUUUUU Examine the millet seeds provided in the kit. Each seed represents an individual living being. There are two seed types: 1) some seeds are round with a smooth exterior; 2) some seeds are slightly wrinkled and have pointed ends. See Figure 9. Round Wrinkled Figure 9. Millet seeds: round or wrinkled. 2 Assume the following about the millet seeds: the character for seed texture has two alleles, the round seed allele (R) and the wrinkled seed allele (r). Complete...

Observed F2 generation: Count the seed color and texture phenotypes for 100 seeds. How many of the observed offspring are purple, round? What percentage ? How many of the observed offspring are purple, wrinkled? What percentage ? How many of the observed offspring are yellow, round? What percentage ? How many of the observed offspring are yellow, wrinkled? What percentage ? Are these observed percentages similar to the expected percentages?
