Summary:  Macromolecules are organic compounds that contain carbon.  The elements found in these compounds are carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus.  There are four macromolecules, lipids, carbohydrates, nucleic acids, and proteins.  Lipids store energy and they make up most of the cell, some examples are things like fats, oils, and waxes. They are made carbon, hydrogen, and oxygen. Carbohydrates are the ones that give you energy. They are made of carbon, hydrogen, and oxygen. Proteins regulate growth, development, and transport oxygen and other substances. There made from carbon, hydrogen, oxygen, nitrogen, and sulfur.  Nucleic acids are the instructions for the cell. They are made of carbon, hydrogen, oxygen, nitrogen, and phosphorus. The two examples of them are RNA and DNA. SP2: I used the photosithesis lab to test different variables to see what would produce the most oxygen.   T he light intensit...

Video: Summary:  The Golgi Apparatus is a very important organelle in the cell. The Golgi Apparatus is is a “packaging organelle”. It is also known as the post office for the cell.The Golgi Apparatus gathers simple molecules and combines them to create complex molecules. Then packages the complex molecules in vesicles and either stores them or sends them out of the cell. It works with the Endoplasmic Reticulum as it modifies, packages, and ships lipids and proteins synthesized by the ER. The Golgi Apparatus also works with the ribosomes as the ribosomes make the proteins and it ships the proteins to the ER and so on and so forth. The structure of the Golgi apparatus is kind of like a pancake is you think about the material. The Golgi Apparatus is made several flattened membranes sacs, but can be ultimately divided into two sections: the Cis Golgi and the Trans Golgi Network (TGN). The Cis Golgi functions as the receiving end for newly synthesized proteins from the Endoplasmic...

Summary : Most organelles have nuclear DNA and don't cause any problems. The mitochondria however may cause conflict in the cell. The  mitochondria has it's own DNA which they had gotten from their mother. Their DNA causes them to be able to slightly influence what they do. As a group the cell will want the mitochondria to produce a lot of energy while the Mitochondria would instead want to reproduce as much as they could therefore causing conflict in the cell. The mitochondria is greedy! Therefore they are not fit to be president of the cell. SP7 - Engaging in argument from evidence: I was able to engage in arguments against other campaigns by defending the Golgi Apparatus ans smearing other organelles that I (and teammates) found incapable of the job as "president". One issue that came up a lot is that the Golgi leads to Achondrogenesis an d  Alzheimer's. A lthough this is true, these are only Golgi bodies that have malfunctioned that caus...

www.glogster.com Summary:  Also known as the Golgi Body, the Golgi Apparatus is i s a “packaging organelle”. In fact it is known as the post office of the cell. The Golgi Apparatus g athers simple molecules and combines them to create complex molecules. Then packages the complex molecules in vesicles and either stores them or sends them out of the cell. It works with the Endoplasmic Reticulum as it m odifies, packages, and ships lipids and proteins synthesized by the ER. The Golgi Apparatus was actually one of the first organelles to be observed. A Italian physician named Camillo Golgi discovered it when he was investigating the nervous system. SP7: Engaging in argument from evidence:   I examined my own understanding in light of the evidence. I used to think that the Golgi Apparatus was the only packaging cell and it worked alone, but because of further research on the Golgi Apparatus now I know that the Golgi Apparatus works with the ER and the ribosomes. The r...
