Exploring Levels of Organization For this lab, you will be using the 500x digital microscope and various internet sites. You will first explore some one celled organisms and then look at the different levels of organization in larger multi-celled species. First, you will look at four different types of single celled organisms. After you have found them using the 500x microscope, you will draw a sketch of what you see in the correct box. Then, you will use google images to find even more detailed pictures of the same organisms. Sketch what you see.

euglena Digital Scope Sketch Google Sketch Euglena are microscopic one celled organisms that typically live in water. They contain chlorophyll and can undergo photosynthesis. They can also eat other microscopic organisms to get energy.

amoeba Digital Scope Sketch Google Sketch amoebas live in water and must catch and eat other microscopic organisms to get energy. The amoeba can change its shape and uses this characteristic to wrap around and digest anything it eats.

2 Exploring Levels of Organization

protozoa Digital Scope Sketch Google Sketch protozoa can come in many different shapes. They are all microscopic and have to eat other microorganisms to get their energy. Protozoa are also eukaryotes, which means they have a membrane bound organelles.

paramecium Digital Scope Sketch Google Sketch paramecium can live in water, soil, and even inside living things. They move by using tiny hairs called cilia. The cilia are too small to see under the microscope. Paramecium cannot make their own food and have to catch other microscopic organism to get energy.

1. Which of these four microorganisms is a producer?

2. Which three of these microorganisms are consumers?

3 Exploring Levels of Organization

Now, go to the following web site to perform a virtual dissection of a plant and an animal. You will be able to see all of the levels of organization except the cell. http://www.livebinders.com/play/play/275892

First go to the tab that says “Parts of a Flower”. Start with Case 1. Click “Mysteries” at the bottom of the screen, the “What are the Parts of a Plant” and begin the game. Complete the information below: WORD BANK: stem leaves roots flower fruit seed

1. Carries water and food through the plant. 2. Carries and protects the seed.

3. Allows the plant to reproduce. 4. Helps the plant to produce seeds.

5. Made of the blade and the petiole.

6 Take up nutrients and water. Now click on “click here to see if you know where each part is located”. Label the plant parts:

Now go to “Case 4”, then click on “Facts” then “Parts of a Flower”. Read through the information and use it to label the following picture. Place the name of the plant part here.

Now, you will do a virtual frog dissection. Go to this website and follow the instructions.

http://www.roketoyun.com/frog-dissection.asp Then, go to this website so you can label the main organs of the frog.

http://froggy.lbl.gov/cgi-bin/dissect Start out by unchecking all of the boxes. Click only one box at a time and try to figure out what each part below is. Label the part correctly.

6 Exploring Levels of Organization

Questions: 1. What did both the plant and animal have in common during the virtual dissection?

2. How is a living organism a system? (hint: a system has many smaller working parts).

3. What parts of the system could you identify?

4. How are the parts of the organism highly organized?

If there is time left, go to these sites and watch the frog, cow eye and sheep brain dissection. Make sure you get headphones.
