BIO 204 Week 1 Individual Assignment Plant Cell Organelles and Their Functions For more classes visit www.snaptutorial.com What is the interdependent relationship between mitochondria and other organelles? What are similarities and differences between the Golgi apparatus and the large central vacuole? What is the function of chloroplast? Include functions of stroma and grana. Explain the function of the smooth endoplasmic reticulum and rough endoplasmic reticulum. How are their functions similar to the nucleus’? How are they different? Provide three unique chemical or physical properties of water. How are these properties useful to water movement in plant cells? Discuss similarities and differences between bulk flow and diffusion. What are driving forces behind each process? Describe Fick’s law. How might this law be applied to osmosis? Explain how osmosis is a special case of diffusion.
- 2. What role does solute concentration play in osmosis? How does water’s chemical potential influence osmosis? What role do water properties play in diffusion? Distinguish between osmotic pressure and potential. What organelle is related to osmotic potential? What role do aquaporins play in cell membrane permeability? What controls the gating of aquaporins? **************************************************** BIO 204 Week 2 Individual Assignment Plant Nutrient Functions and Deficiency Symptoms For more classes visit www.snaptutorial.com BIO 204 Week 2 Individual Assignment Plant Nutrient Functions and Deficiency Symptoms

What environmental factors control stomatal movement? How are these factors related to physical and chemical properties that control the opening and closing of stomata? What are primary stages in the photosynthetic carbon reduction (PCR) cycle? Explain the role of each stage. Draw a diagram of the stages by utilizing drawing tools in Microsoft Word to aid your explanation.
- 5. Explain how the ATP and NADPH produced by the photosynthetic electron transport chain are used in the PCR cycle. What roles do light and Rubisco play in regulating the PCR cycle? Explain your answer. Explain how cells release energy through glycolysis, respiration, and fermentation. Identify pathways in each stage. Describe each stage’s role in releasing energy. What is the role of enzymes in degrading starch and sugar? Explain your answer. Discuss some similarities and differences between respiration and fermentation. Aerobic organisms are usually larger than anaerobic organisms. Suggest how this might be related to respiration. **************************************************** BIO 204 Week 5 Individual Assignment Phototropism Virtual Laboratory
- 6. For more classes visit www.snaptutorial.com Introduction: Provide readers with the experiment’s background information and present the hypothesis in two paragraphs. The introduction is written in the present tense. Include the following points: Discuss the difference between growth and turgor movement in plants. Define phototropism and gravitropism, and explain fundamental mechanisms of each movement. Indicate why studying tropisms are important for plant science. State your hypothesis of how meristem movement occurs in plants in response to sunlight. Explain how your hypothesis will be tested. In one or two sentences, explain what you expect will happen and include at least one alternative outcome. Methods: In two paragraphs, describe how the phototropism experiment was conducted. Include the following points: Experimental design: Describe treatments for the test seedling, and positive and negative controls. Why does the experiment include all three treatments? What does each treatment allow you to understand? Data collection: How did you collect data? Over what time period was it collected? Results: In no less than two paragraphs, describe the results. Include the following points: Begin with a one- or two-sentence summary of your findings.
- 7. Include the graph generated from your spreadsheet. Your graphs must be labeled. Summarize results discovered in each graph and compare results. Discussion: In no less than four paragraphs, describe your findings and consider their importance to plant science. Include the following points: Summarize findings. State whether or not your hypothesis was supported. Explain how phototropism occurs. Include at least one explanation from the textbook. Do your results allow you to support the explanation with 100% certainty? Why or why not? Conclusion. Offer a summary of your findings. Indicate how this experiment will help scientists understand phototropism. Offer at least one example of what still must be learned about phototropism. **************************************************** BIO 204 Week 5 Learning Team Assignment Role of Major Hormones Presentation

For more classes visit www.snaptutorial.com BIO 204 Week 5 Learning Team Assignment Role of Major Hormones Presentation Create a 10- to 14-slide (Title and Reference slides) Microsoft® PowerPoint® presentation that examines one plant hormone and its role in plant growth and function. Basic requirements for all Powerpoint Presentations: Incorporate the following elements into your presentation, information should be present in the SLIDE NOTES: Provide an overview of your plant hormone. Provide a brief history of scientific inquiry surrounding your hormone. Describe one experiment that led to understanding the hormone's function. Describe the development of structures involved in plant growth, meristems, cambium, flowers, and seeds. What plant structures and functions are associated with the hormone? Explain how it influences plant growth and function. Include a picture to support your explanation. To locate the picture you want to use, select a search engine, and search
- 9. for the image. Be sure your image is clear and contains an APA formatted in-text citation. Provide a photo or diagram (with an APA formatted in-text citation) and an explanation of the effects of hormone deficiency and excess on plant growth or function. Review the main points of the presentation and summarize the hormone's major function for plant growth as a conclusion. Include elegant graphics and a reference slide with citations for photos, cartoons, diagrams, and other references. ****************************************************
