1. Warm Up:
1. All of the following organisms have eukaryotic cells EXCEPT:
Plantae
Fungi
Bacteria
Animalia

2. Cell Structure and Function
Cell organelles and what they do, from the outside in!

3. Lipids -fat molecules
Lipid bilayer -cell membrane fat molecules arranged in 2 layers prevents water soluble molecules from passing
Protein molecules -receptor proteins, allows specific molecules to move in or out of a cell

4. active transporter (calcium pump) active transporter (ATPase pump)
adhesion protein
passive transporter
recognition

6. Cell Membrane
The cell membrane consists of a phospholipid bi-layer in which proteins are embedded to varying degrees.
Hydrophilic phosphate heads point toward the outside of the cell, while the hydrophobic lipid tails point inward toward the nucleus of the cell.

7. Cell membrane
The structure enveloping a cell, enclosing the cytoplasm and forming a selective permeability barrier. It is inside the cell wall in plant cells, while it is the only barrier between the outside of the cell and the cytoplasm in animal cells

8. Cell membrane

9. Phospholipid bilayer with embedded protein

10. Plants have cell walls attached to their cell membranes

11. Cytoplasm
Cytoplasm is a gelatinous, semi-transparent fluid that "fills" most cells.
It contains all cell organelles except the nucleus and the cell membrane.
All the functions for cell expansion, growth and replication are carried out in the cytoplasm of the cell

12. Mitochondria
Mitochondria are sometimes described as "cellular power plants," because they generate most of the cell's supply of ATP, used as a source of chemical energy.

13. Mitochondria

14. Golgi apparatus
The primary function of the Golgi apparatus is to process and package proteins synthesized by the cell (In the Endoplasmic Reticulum.)
Some of these will eventually end up as integral membrane proteins embedded in the cell membrane.
Other proteins moving through the Golgi will end up in lysosomes.
Some proteins will be excreted by exocytosis.

15. Golgi Apparatus

16. Endoplasmic Reticulum
The endoplasmic reticulum (ER) is responsible for the production of the protein and lipid components of most of the cell's organelles.
The ER contains a great amount of folds - but the membrane forms a single sheet enclosing a single closed sac.

17. Endoplasmic Reticulum

18. Nucleus
The nucleus contains most of the cell’s genetic material in the form of DNA.
DNA is stored in structures called genes.
Genes make up structures called chromosomes.

19. Animal cell with nucleus

20. Close up of nucleus
Nucleolus and nuclear pores are shown.

21. Cell Processes Passive transport
Passive transport is a means of moving substances across the cell membrane. Unlike active transport, this process does not require energy. Two main kinds of passive transport are diffusion and osmosis.
