1. Micelle Ring of Phospholipids where the tails avoid water,
pointing inwards
Can be in a Single or Bilayer structure
2. Head of a Phospholipid Polar Portion
Hydrophilic
Charger POrtion
3. Tail of a phosholipid Non-Polar Portion
Hyrdophobic
Charged Portion
4. Active Transport Transports molecules against the concentration gradi-
ent (low>high)
Requires Energy
Requires Proteins
5. Carrier Proteins Integral Membrane
Passivley transports large molecules via facilitated dif-
fusion
Is specifically shaped to a single molecule
*How glucose goes into a cell*
6. Proton Pumps Activley transport moleculesto sides of a membrane
7. Channel Protiens Slightly charged to attract ions
Molecules continue to flow through the protien as

other molecules which are also attracted push them
through
Used in faciltated diffusion
8. Vessicle transports materials
sac made up of phospholipid bilayer
9. Vacuole water and food storage
transports waster
larger in plants
10. Nucleus The region of eukaryotic cells where growth and re-
production occur
11. Nucleolus the dense part of the nuclus
where ribosomes are made
12. Cytoskeleton structually supports the cell
stick like fibers
13. Cytoplasm The fluid that hold the organelles in place
14. Chloroplast only in plant cells
where phoynthesis occurs
has two membranes

seen in mitosis and meiosis
assists in the reproduction of Dna by separating sister
chromatids
16. cell wall found in plant cells only
adds structure to the plant cell
17. Endoplasmic reticulum there is a rough ER and a smooth ER
Rough ER
-where proteins are made
Smooth ER
-where fats and oils are produced
Tube like structure near the nucleus
18. Golgi apparatus packages stuff from RER (protiens) into vessicles
19. Flagella Found in prokaryotic cells and animal cells
helps cell to move
20. lysosomes cleans/digests food
destroys bacteria and old organelles
not found in plants of prokaryotic cells
21. mitochondria where atp is produced and where the process of cel-
lular respiration occurs
has 2 membranes
