Learning about Cells Activity- Young & Douthit
Types of Cells Activity
1. Research the two basic types of cells.
a. Use a sketch program to draw a diagram to show the basic construction of each cell type
This is a picture of the Prokaryote cell. It shows the nucelear area, plasmid, and inclusion. It does not have a nucleus. It is a more simple cell. The organelles it has float in the cytoplasm.
This is a picture of the Eukaryote cell. It shows the nucelus, mitochondria, and ribosomes. It is different than the prokaryote because it has a nucelus. Also, this cell is typically larger than the prokaryote. As you can see, it contains more organelles.
b. Place the name of the cell type as a title above your drawing
c. Add at least three labels to your diagram
d. Underneath the diagram add a caption consisting of at least two sentences describing the cell type
2. Chose 2 slides from the slide tray that will show actual cells that demonstrate the two basic types of cells.(One of your slides demonstrates one type of cell while the other slide demonstrates the second type).
Eukaryote Cell: Stentor:
This is a picture of a stentor cell. It is a eukaryote. You can see its nucleus and other organelles. Also, you can see vacuoles.
Photo by wikimedia This is a prokaryot cell because it is simple and has no nucleus in it. This is a Bacillus Bacteria to be exact.
a. Use the moticam to take a photo of each type of cell
b. Place the name of the cell and its type as a title above your photos
c. Place a two or more sentence caption below the photo to describe the cells. Make sure you point out the reasons for why it is one type or the other.
Alternate activity for #2: Find appropriate pictures of the two types of cells from wikipedia or creative commons and attribute the pictures correctly. Follow through with steps a, b, c above.
3. Compare and contrast the two basic types of cells.
Prokaryotes are simpler cells. Eukaryotes are more complex, enhanced cells. In prokaryotes, there is no nucelus, and structures float around freely in the cytoplasm. Eukaryotes are the opposite. Both cells contain ribosomes, cytoplasm, and cell walls. Although, in the prokaryotic cell, ribosomes are smaller and the cell wall is not made out of cellulose, but peptidoglycan. Eukaryotic cells are typically much larger than prokaryotic. During reproduction, the eukaryotic cells use meiosis, while the prokaryotic cells do not.
4. What question do you still have about what you have learned from the activity? State your question, then do research to answer. List your sources of information(at least two).
Stephanie: Do the prokaryotic cells have organelles like the eukaryotic? Yes. They have organelles, but not really as many. They were once believed to not even have organelles. Examples of prokaryotic organelles include flagellum, ribosomes, and plasmid. Examples of the eukaryotic organelles include ribosomes, cilium, and vesicles.
