Eukaryotic Cells
It’s what you are made of!

2. Organelles all Eukaryotes share
Nucleus
Ribosomes
Endoplasmic reticulum
Golgi apparatus
Lysosomes
Vacuoles
Mitochondria
Cytoplasm
Cytoskeleton
Cell membrane

3. Nucleus
Contains the DNA that holds the genetic code for making proteins
The DNA is held on strands called chromosomes
The nucleus is surrounded by the nuclear envelope

4. Ribosomes
Ribosomes can float freely in the cytoplasm or be attached to the endoplasmic reticulum
They assemble the proteins for the cell
Think:
Analogy- if the cell was a city what would the ribosomes be?

5. Endoplasmic reticulum
Lipids are made in the ER
Both lipids and proteins are transported through the ER to the outside of the cell.

6. Golgi apparatus
It modifies, sorts, and packages proteins and other materials
These materials are either stored in the golgi apparatus or secreted out of the cell
think:
Analogy- if the cell was a city what would the golgi apparatus be?

7. Lysosomes Small organelles filled with enzymes
The enzymes breakdown large compounds such as lipids, carbohydrates and proteins.
The cell then reuses the smaller compounds to make new ones

8. Vacuoles & cytoplasm
Vacuoles store water, salt, proteins and carbohydrates
Vacuoles also serve as support structures in plants
The cytoplasm is the fluid that fills the cell in which all the other organelles float.

9. Mitochondria
Mitochondria convert chemical energy stored in food into smaller compounds
Respiration occurs in the mitochondria
think:
Analogy- if the cell was a city what would the mitochondria be?

10. Cell membrane & cytoskeleton
The cell membrane is the boundary between the cell and it’s environment
The cytoskeleton is a network of protein filaments that help the cell keep its shape

11. Chloroplasts
Chloroplasts are found only in plant cells and a few protists
Photosynthesis, the process that converts solar energy to chemical energy, occurs here

12. Summary Which organelle makes proteins for the cell?
Which organelle breaks apart large molecules?
Which organelle sorts and packages materials for the cell?
