3.03 The Cell: Prokaryotes...Simple Cells

Weren't the Pyramids inspiring? l know the drive yesterday was a long one, and we have a bit of a drive today, but I think you'll find it was worth the time on the road. Our next stop is the Valley of the Kings.

Dr. Q, my old college professor, sent a letter a while back saying that he would be there digging out a tomb in the valley. He asked that we come visit his dig site to see what he has found. I must admit though that I am a little hesitant. In the letter he mentioned several of his workers getting a mysterious illness. They think it is bacterial, so we'll have to be careful while we're there. I don't want any of you getting sick!

In this activity you will: define prokaryote type cell recognize the parts of a prokaryote type cell state that only bacteria have prokaryote type cells

Cells

Gee, I wonder if we'll need to help Dr. Q figure out what is making his workers sick. Let's investigate cells a bit more on the way this morning. Knowing cell basics may come in handy in looking at specimens from the sick workers. So to continue our study of cells:

all cells are classified into 2 groups:

1. Prokaryote cells
2. Eukaryote cells

The names are a lot harder to say than their meaning.

1. Prokaryote cells are simple cells that do not contain many parts, and the genetic material is not enclosed in a membrane bound nucleus.
2. Eukaryote cells are more complex with a lot of different internal parts, and their genetic material is enclosed in a membrane bound nucleus.

Study the two diagrams and see if you can determine exactly what the differences are!

We're here. There's the entrance to Dr. Q's dig site. Watch out for that snake! What kinds of cells make up the snake's body? Yep, "Eu got it"! Eukaryote cells! (Sorry, couldn't resist that one!) Man, I hate snakes! Let's go in!
