1. List the three laws of cell theory from memory. (on NBP)

A.

B.

C.

2. What is the difference between a prokaryote and a eukaryote?

Catalyst Answer 1. The three laws of Cell Theory are…. A. All living things are made of cells. B. Cells are the basic units of structure and function in all living things. In other words, cells are like the building blocks of all living things. C. New cells are only made from existing cells. 2. Prokaryotic cells do not have a nucleus and eukaryotic cells have a nucleus.

1. The three laws of Cell Theory are….

A. All living things are made of cells.

B. Cells are the basic units of structure and function in all living things. In other words, cells are like the building blocks of all living things.

C. New cells are only made from existing cells.

2. Prokaryotic cells do not have a nucleus and eukaryotic cells have a nucleus.

Let’s review what we know about prokaryotes …. 1. Prokaryotes do not have a nucleus, and their genetic material is not stored in the nucleus. Prokaryotes have some organelles, but not many. 3. Prokaryotes are less complicated that eukaryotes. All bacteria are prokaryotes.

1. Prokaryotes do not have a nucleus, and their genetic material is not stored in the nucleus.

Prokaryotes have some organelles, but not many.

3. Prokaryotes are less complicated that eukaryotes.

All bacteria are prokaryotes.

Prokaryotes are simple cells, even though they are still very powerful. Each cell is its own organism. Therefore, it has certain structural features, or a certain shape, that help it to function. There are two things to know about prokaryotic cells: 1. How they are shaped 2. What they use to move

Prokaryotes are simple cells, even though they are still very powerful. Each cell is its own organism. Therefore, it has certain structural features, or a certain shape, that help it to function.

There are two things to know about prokaryotic cells:

1. How they are shaped

2. What they use to move
