2. Questions from yesterday’s lab… (p. 77)
Cell Membranes are flexible….
Is the bubble flexible?
How do you think that this is able to apply to our cells.
Cell membranes are self-sealing…
What objects were able to pass through the membrane without breaking it?
Why do you think that it is important that membranes are able to self seal themselves?
Transport Proteins
What happened when you placed the string circle into the membrane?
Why do you think this happened?
Cell Division
What happened when you cut the bubble with the knife?
Why do you think this is important for our cells?

3. The Nucleus Notes P. 80 What is the function of nucleus of the cell?
Controls most activities in the cell
Contains the genetic information (DNA)
What is the structure of the nucleus of the cell?
Circular structure
Contains a smaller nucleolus
Contains Chromosomes (DNA structure)
Surrounded by a nuclear membrane

4. What is the nuclear membrane?
Also known as nuclear envelope
Membrane that surrounds and protects the nucleus
Regulates what enters/leaves the nucleus

5. Prokaryotic vs. Eukaryotic Cells
Some cells do not have a nucleus. These are prokaryotic cells.
Simplest life forms
Include bacteria
Genetic material “floats” around in the cell
You’ll learn all about these in 8th grade science
Cells that have genetic material enclosed in a nucleus are Eukaryotic cells.
Include plant and animal cells
What we learn about in seventh grade science

7. One-Pager Use plain white paper Use colored pencils or makers
Title your page “Cell’s nucleus”
Use three complete written sentences that convey facts about the cell’s nucleus
Fill the entire page
Place five essential vocabulary words
Put a ½ inch symbolic border around the edge
Use three visual images
Write 2 Higher level questions about the cell’s nucleus you might want to ask someone on a test if you were teaching the subject
