Cell Theory says that….

1. All living things are made of one or more cells.

2. Cells are the basic units of structure and function in all living things. Cells are like the building blocks of life

3. New cells are only made from existing cells. (mitosis and meiosis)

Page 4: Warm- Up: Cells What do you know about cells? –- Where are they found? –- Are there different types? –-Examples of cells types. –- What are cells made

There are two types of cells:

Prokaryotic Cells

and

Eukaryotic Cells

These are two distinct types of cells with STRUCTURAL differences.

Prokaryotes

Bacteria

Eukaryotes

Animal Plant

Prokaryote Cell

A single celled organism that does not have a nucleus.

Add this to your vocabulary book

Page 8: Warm- Up: Cells What do you know about cells? –- Where are they found? –- Are there different types? –-Examples of cells types. –- What are cells made

Traits of Prokaryotes: (pro-care-ee-ohts)

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

2. They have some organelles, but not many.

3. They are less complicated that eukaryotes.

4. All bacteria are prokaryotes.

Bacteria may be small but they are powerful!

During the 14th century, 25% or ¼ of Europe was killed by a killed by a bacteria called the Bubonic Plague, also called Black Death. This bacteria

was spread through fleas and rodents.

But at the same time we need bacteria to live!

1. Bacteria are decomposers and without them all other organisms would not be able to survive.

2. We use bacteria in our digestive system to help digest our food. There are approximately ten times as many bacterial cells as human cells in the human body!

3. We could not make cheese or yogurt without bacteria.

Eukaryote Cell

A more complex cell with a nucleus and many organelles.

Add this to your vocabulary book

Traits of Eukaryotes: (you-care-ee-othts)

1. They all have a nucleus where the genetic material of the cell is stored.

2. They have many organelles that work together to help the cell function.

More traits of Eukaryotes: (you-care-ee-othts)

4. Eukaryotic cells are much more complex then prokaryotic cells.

5. They can be just one cell or can make up more complex multi-cellular organisms.

6. All plants, animals, fungi, and protists are eukaryotic cells.

What do you think is the main difference

between a prokaryotic cell and a eukaryotic

cell?

The nucleus!Prokaryotic cells do not have a

nucleus and eukaryotic cells do have a nucleus. This allows eukaryotic cells to make multi-cellular organisms and perform more complex functions.
