**Cell Structure**  = =  The Golgi complex gabrielle and victoria =The Golgi complex is found in eukaryotes cells. It is similar to the ER. The Golgi complex was named after Camilo Golgi an Italian biologist. Although the membranes of the Golgi complex look similar to the ER they have completely different functions. Lipids and proteins are delivered from the ER to the Golgi complex. The Golgi complex changes and packages proteins ready to export the finished product. When the proteins move threw the Golgi complex it changes their chemicals. In plant cells the material, which makes cell walls, also passes through the Golgi.= = = = = **__ Nucleus __**   ** The nucleus is the organelle that consists of the control center of the cell and the cell’s DNA. A nucleus is like the brain of a cell. **** The nucleus helps to control the movement, eating and reproduction. The nucleus isn’t in middle of every cell. It is a big, dark spot somewhere around the middle of the cytoplasm, (cytoplasm is the what fills a cell.) but not necessarily exactly in the middle. There aren’t nuclei in all cells. If the nucleus was near the edge of the cell it could be a very dangerous area for it to be. ** 

** Endoplasmic Reticulum (Posted By Emma & Lia) ** The Endoplasmic Reticulum, also known as the endomembrane system is a system of membranes that makes lipids and other materials. There are two types of ER, rough ER and smooth ER, which are the two regions of the membranes. The rough ER is called the rough ER because it has ribosomes on its surface. It’s responsible for protein synthesis, because it has ribosomes on it. The smooth ER does not contain ribosomes, but is responsible for the transportation of the proteins manufactured by the rough ER.

__** Vacuoles ** (By Zara H.) __

Vacuoles are found in cells and they act as storage bubbles. They are found in both plant and animal cells, but they are much larger in plant cells. Vacuoles generally store any nutrients and food that the cell needs to survive. Sometimes they even store waste, so the rest of the cell is safe from contamination. Eventually the waste is sent out of the cell. The structure of the vacuole is simple; there is a membrane that surrounds a mass of fluid. The fluid consists of nutrients and waste. Sometimes plants store water inside their vacuoles. The small water bags help with the support of the plant. They are closely related to the vesicles that are found throughout the cell.

 * Mitochondria Structure: By Bhailee Havercroft and Simran Chatani **


 * Mitochondria ** is an organelle that breaks down sugar.

Mitochondria have two membranes. The outer membrane covers and contains the organelle. The inner membrane folds over many times increasing the surface area inside the organelle. Many of the chemical reactions happen on the inner membrane of the mitochondria. The increased surface area allows the organelle to work as much as possible. If you have more room to work, you can get more work done. Similar surface area strategies are used by **microvilli** in your intestinal cells. The fluid inside of the mitochondria is called the **matrix.** **Cytoplasm** is the fluid inside a cell. (by Luke and Cody)

The protoplasm outside the nucleus of a cell. The cell substance between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton, and various particles. Cytosol is the fluid part of cytoplasm. Cytosol is the fluid component of a cell's cytoplasm including everything except the nucleus and the cell membrane. This special cell is made of everything but the nucleus and cell wall. The cell holds itself as a jelly like substance and when stirred it becomes a liquid substance. This cell is a multi purpose cell and the liquid that you see on the cell is 80% water and looks clear.
