Assignment Details

Photosynthesis and Chloroplasts

You will read that only plants, algae, and some bacteria are photosynthetic. There is an exception to this, however. One species of sea slug has found a way to steal chloroplasts, store them in glands lining its digestive tract, and live on the sugar that is produced (Milius, 2010).

Focus your discussion on 1 of the following topics:

  • Describe at least 2 benefits and 2 drawbacks there might be for animal cells (including humans) to make their own food through photosynthesis.
  • Explain which cells, tissues, or organs should be modified to lead to successful photosynthesis in animals. Discuss how this compares to a plant’s leaves.
  • Describe at least 1 requirement for photosynthesis that would need to be considered for chloroplasts to function in an animal or a human.
  • Predict 2 or more consequences of photosynthesis in humans.

Unit VIII Homework

Plant Transpiration

 

Introduction

 

If you have not already, you or someone you know will try to grow a variety of plants either inside your house or outside in a garden. What type of soil do you need? How often should you water the plants? Should you plant them in full sun? Why do some plants need less water and some more? These are questions that many people have about plants. In this activity, you will have a chance to manipulate different variables to see how much water some plants use and how much some lose through transpiration.

 

Objectives

 

1.     Conduct virtual experiments to determine factors that affect transpiration.

2.     Compare and contrast sustainable and unsustainable farming practices.

Materials

 

Computer with internet access

3.     Read and follow the information under PROCEDURES, and complete the lab for all 4 plants and all 3 variables.

4.     Reset the lab and complete the lab for the next set of 4 plants and 3 variables.

5.     Record your information in the Results Table provided on this sheet.

6.     During and after the lab, answer the questions below.

11.  You want to reduce the amount of money that you are spending at the grocery store. You and your family decide to plant a small garden to provide a variety of foods. Since you completed the activity above, you know that plants require certain nutrients in order to survive.

 

Read the information in the textbook concerning the future of agriculture (pages 586 – 592). What are some methods that you would implement into your garden? What would you try to avoid? In addition to your textbook, locate at least one article in the CSU Online Library that provides further information on your chosen methods. Make sure you provide a detailed response.

Determine which type of car would work best for you and your family. Justify your decision based on your analysis of the five hybrid cars.

/in /by

A hybrid car is a motor vehicle that uses two or more different sources of power. In most hybrids, you will find an internal combustion engine in addition to an electrical motor. Depending on how the vehicle is driven and the availability of power, the car uses gasoline and battery power alternately.

In this assignment, you will research five different hybrid cars and evaluate their impact on the environment.

Using the readings for this module, the Argosy University online library resources, and the Internet, do the following:

· Identify the top five most popular choices of hybrid cars. Analyze the advantages and disadvantages of each car’s technology, price, manufacturing, and impact on environment. Include the scientific principles involved in the technology.

· Determine which type of car would work best for you and your family. Justify your decision based on your analysis of the five hybrid cars.

· Explain the impact these cars will have on the United States’ economy. Consider the following issues in your analysis: consumer buying, sustainability, recycling, and fuel economy.

· Evaluate the impact that hybrid-car technology has had or could have on the United States’ political relationships with oil-producing countries. Be sure to include an analysis of economic issues such as production, supply, and trade.

· Describe how this technology will influence world politics. Include an analysis of economic issues such as production, supply, and trade.

Support your statements with examples. Use a minimum of six reliable references, two of which should be peer-reviewed articles.

Write a 4–6-page paper in Word format. Apply APA standards to citation of sources, please include link to the references. Use the following file naming convention: LastnameFirstInitial_M3_A2.doc.
