1. KEY CONCEPT Eukaryotic cells share many similarities.

2. Cells have an internal structure.

3. Cells have an internal structure.
The cytoskeleton has many functions.
supports and shapes cell (microtubules)
helps position and transport organelles (microtubules)
provides strength (intermediate filaments)
assists in cell division (microtubules)
aids in cell movement (microfilaments)

4. Several organelles are involved in making and processing proteins.

5. Several organelles are involved in making and processing proteins.
The nucleus stores genetic information (DNA).
The nucleus protects the DNA and activates genes when needed.
The nucleus also contains the nucleolus ,which assembles ribosomes for making proteins.

6. Several organelles are involved in making and processing proteins.
Many processes occur in the endoplasmic reticulum involving protein production and processing.

7. Several organelles are involved in making and processing proteins.
There are two types of endoplasmic reticulum.
rough endoplasmic reticulum
smooth endoplasmic reticulum

8. Several organelles are involved in making and processing proteins
Several organelles are involved in making and processing proteins. (continued)
The rough ER contains ribosomes and makes proteins.
The smooth ER does not have ribosomes and make lipids.
