In the life cycles you have examined so far, what features do you consider to be adapted to a terrestrial environment? Explain
at the time of their evolution, plants have adapted some terrestrial existence. Because they have to occupy some, specialized, ecological niches that are deserts, rainforests, and aquatic environments.
those adaptations allowed plants to overcome from the challenges of a dry environment and support growth.
These adaptive features of the terrestrial environment are the following: the presence of cuticles, stomata, vascular tissue that is xylem and phloem, gametangia, and seeds.
Waxy Cuticles and Stomata- reduce the rate of transpiration in case of low availability of water
Plant Phylogeny also play a very important role in adaptation
Alternation of Generations: The Moss Life Cycle is play important role in evolution.

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.
What recent design features on roads do you consider have improved safety and what features, if any, do you consider have increased danger? Also, which innovations would you consider could improve road safety?
So far in your life, you may have assumed that as you are sitting in your chair right now, you are not accelerating. However, this picture is not quite complete! You are on the surface of the Earth, which is rotating. 1. a) What is the acceleration of a person sitting in a chair on the equator? b) The latitude of Corvallis is 44.4". What is your acceleration while sitting in your chair? (c) Is your apparent weight greater than,...
Discuss what you have learned so far in the course to compare quantitative and qualitative research: 1) discuss the similarities and differences in these research approaches. 2) Discuss the key features of each approach and give an example of a research question that might be asked for each.
So far we have examined the four financial statements: Income Statement, Statement of Stockholders' Equity, Balance Sheet and Cash Flow Statement. Briefly discuss the four statements. Which is the most useful to external users and why?
Based on what you have learned so far about Doughnut Economics. Do you think the principles can be adopted in time to avoid significant problems and even catastrophe for humanity? Why or why not? If so there is time, how may the adoption might unfold over the next two decades?
Examine the life cycles of the 3 main groups of plants. What do you notice about the sporophyte and gametophyte stages as plants evolved from mosses to ferns to pine trees?
So far in this course, you have seen real-life applications of linear equations, linear inequalities, and linear systems. In your initial post to this forum, create a word problem related to your major for each of these three concepts. Review the applications in the text and the video lectures for ideas. You will also find many examples on the Internet as well. In the post, include the following: My major is Baking and Pastry, so all three concepts have to...
Based on what we've learned so far, what do you think human skin tones will look like 100,000 years from now? (assuming humans are not extinct!) Consider factors such as natural selection, founder effect, genetic drift, vitamin D, folate, etc.
What do plants go through alternation of generations life cycles ? In other words, what is the purpose of this process ?
