FC: The Eukaryotic Cell

1: -Membrane bound nucleus | Eukaryotic Cells | -Greek meaning of "true nucleus." | -Contain membrane-bound organelles. | -Each organelle has its own specific job within the cell. | -Eukaryotic cells make up animals, plants, humans etc.

2: Cell Membrane | -Encloses all the organelles inside the cell. | -Proteins and Phospholipids make up the cell membrane. | -Proteins are also what enable molecules to enter and exit the cell. | Phospholipids have a head and tail the head is called hydrophillic because it is like water and the tail is called hydrophobic because is does not like water. | -When you think of the cell membrane think of a plastic bag. | "gate keper"

3: Cell Wall | -Made of cellulose which is only around plants cells. | -Cellulose is a sugar and structural carbohydrate. | -Cellulose is structural carbohydrate because it helps keep the plant strong, grow, and keep its shape. | -Plasmodesmata is in the cell wall and helps the cell release wastes and take in nutrients.

4: Cytoplasm | -Helps move materials around inside the cell. | -Fluid that fills a cell. | -Holds all the organelles together. | -Molecules like fatty acids, amino acids & sugars are in cytoplasm. | -80% water.

5: Cytoskeleton. | -An array of protiens that help the cell keep its shape, keep it strong, aid in mitosis, and inercellular transport of organelles. | -It helps the internal movement of the organelles | -The cytoskeleton acts as the 'bones' to the cell.

6: Nucleus. | The nucleus is the brain/headquarters of the cell, it control movement, reproduction and eating. Contains DNA and RNA. Is the dark spot in a cell. There is a nucleus inside the nucleus called the nucleolus.

7: Nucleolus | Made up of RNA and protein. | Manufactures ribosomes | Found in the nucleus | "The brain inside the brain"

8: Ribosomes | -Protein builders. | -Found everywhere in cell, floating in cytoplasm, or on ER. | -Made up of 60-S and 40-S. | -When 60-S and 40-S are combined they create mRNA. | -mRNA is sent to the nucleus to make protein.

9: Endoplasmic Reticular (Rough) | The Endoplasmic Reticluar or ER is the cell's so called packaging system. It works together with the Golgi aparatus, ribosomes, and the different types of RNA. Has the same type of membrane as the smooth ER but different shapes. Ribosomes are attached to the outside of the ER making the membrane rough. This ER specifically helps with packaging proteins .

10: Endoplasmic Reticular (Smooth) | -Stores steroids and ions for whenever they are needed. | -Storage organelle. | -Outside is not covered in any ribosomes. | -Works in liver to detoxify compounds. | -Works in brain to release male or female hormones. | -Works in the muscles the contract muscles.

11: Golgi Apparatus | -Packaging system much like the ER. | -Gathers and combines simple and complex molecules into other molecules or vesicles. | -Builds lysosomes | -Series of membranes shaped like pancakes.

12: Vacuoles | Called the "Storage unit" | Helps the structure of the cell, because they gain and obsorb water that is nessesary for the cell. | Store food or nutrients needed for the cell to survive. They can even store waste. | Their structure is a circular bubble shape that has an outer membrane covering it.

13: Centrioles | Located near the nucleus but when it comes time to divide they reveal themselves | They are made up of nine groups of specificly placed microtubles | They help when the cell goes through mitosis or miosis. (when the cells divide) | Could be called "The nurse" of the cell. | Microtubles are fibrous hollow rods that help keep support the cell shape.

14: Mitochondria | Act as the "Digestive System" of the cell. But is called the "Power House" of the cell. | -It takes in nutrients,breaks it down, then creates energy for cells. | -Each cell has several thousand mitochondria. | There is an inner and outer membrane inside each organelle.

15: Chloroplast | Only found in plant cells not animal cells. | They produce food for the cell. | They make food for the plants because plants can't get an outside food source. | Can be called "kitchen" of the cell because it makes energy for the cell/plant.

16: Cilia&Flagella | Protisis are eukaryotes with advanced structures. | Cilia are the short little hairs that you might see on the outside of the protisis, that help it move by flapping back and forth. | Cilia & Flagella are the "wheels"of the cell because they help the cell move.. | Flagella are the long tails that curl up and push out; it helps move the cell around
