1. Erin and Brooke

2. Prokaryotic Cells Prokaryotic cells = BACTERIA It has no true nucleus or organelles. Instead it just has DNA, RNA, chrosomes, cytoplasm, a cell wall, and cell membrane. There are no organelles The “POOR PRIMITVE PROKARYOTE”

3. Eukaryotic Cells Eukaryotic cells are plant, animal, and protist animal cells!! Have cell organelles. Eu = means True Karyote = cell The following organelles are all found in Eukaryotic Cells

4. Cell Membrane Eukaryotic and Prokaryotic cells have cell membranes. In the eukaryotic cell membrane is the outmost part of an animal cell, controls what enters and exits in the plant cells (Figure 1).

5. The Cell Wall Like the Cell membrane, the cell wall also is in both Prokaryotic and Eukaryotic cells. Cell membranes are found on the outermost part of plant and bacteria cells, they are flat and rigid, are used for support in the cell.

6. Nucleus The nucleus is ONLY found in the Eukaryotic cells. It is located in the middle of animal cells It contains DNA, controls the activities of the cell, and cellular reproduction.

7. Ribosomes When looking at a picture of a cell you can locate the ribosomes very easily. They are the small dots seen on the endoplasmic reticulum. The ribosome contains RNA and produce proteins for the cell.

8. Golgi Apparatus Found in Eukaryotic cells. The job of the Golgi is to modify, sort, and package the proteins of the cells. Its is like the cell post office.

9. Smooth Endoplasmic Reticulum Found in Eukaryotic cells. This type of ER does not have ribosomes on it so it looks smooth. Functions - synthesis of lipids and steroids, metabolism of carbohydrates, regulation of calcium concentration, drug detoxification, attachment of receptors on cell membrane proteins, and steroid metabolism.

10. Rough Endoplasmic Reticulum “ER” Rough ER has Ribosomes attached to it. It looks rough under a microscope. Endo = inside Plasmic = the plasma Reticulum = connector Endoplasmic Reticulum – connectors ( like tunnels) found inside the plasma.

11. Vacuole Is found in Eukaryotic cells. In plant cells it stores food and is found in the center of the cell. It is really BIG and called a Central Vacuole It stores water in animal cells and is fairly small.

12. Chloroplast Are found in plant cells (eukaryotic). They produce energy/food for the cell using sunlight. They are the “Green things” in plant cells. Photosynthesis occurs in chloroplast.

13. Mitochondria Has a double membrane ( 2 layers) Known as the “powerhouse” of the cell. Its job is getting energy for the cell which is called respiration. The “Mighty Mitochondria”

14. Comparing Prokaryotic Cells & Eukaryotic Cells Prokaryotic CellsEukaryotic Cells Cell Wall Yes Cell Membrane or Plasma Membrane Yes Chromosomes Yes Cytoplasm or Protoplasm Yes Mitochondria No Yes Ribosomes No Yes Nucleus No Yes Vacuoles No Yes Golgi Bodies No Yes Chloroplasts No Yes

15. Plant Cells & Animal Cells are both Eukaryotes Plant & Animal Cell Comparisons Plant CellsAnimal Cells Cell Wall Yes No Chloroplasts Yes No Central Vacuole Yes No Nucleus Yes Mitochondria Yes Ribosomes Yes Endoplasmic Reticulum (both types) Yes Golgi Bodies Yes Cell Membrane Yes
