Just like complex organisms, cells are able to survive by coordinating various activities. The body contains many organs and organelles to maintain specific order and allow the body to survive. One example of one of the body’s main organelles is the nucleus. The nucleus contains most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes. The nucleus’ function is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression. The nucleus is known as the “brain” of the body. It sends information and controls the body’s activities. If you were to compare the nucleus with a human body system, it would most likely be best related with the nervous system. The nervous system includes the brain which the nucleus is most closely related with. The brain sends information throughout the body and controls what goes on. Another important organelle of the body is the ribosomes. The ribosomes are small particles in the body in which complexes of RNA and proteins are found. The nucleus and the ribosomes work together to produce many bodily functions. For example, the nucleus sends information to the ribosome on how instructions to how to make the proteins, and what “ingredients” are included in the production. So, if your ever wondering why are organelles so important? Well its because they are the ones who control the what goes on inside of your body! --Brittany H.
1) One organelle is the nucleus and another organelle is the ribosome. A nucleus acts as the control center for the cell. Ribosome job is to assemble amino acids into proteins under the direction of the cell's DNA 2) The nucleus contains DNA in the form of chromosomes. The DNA gets transcribed into RNA, which is translated by the ribosomes into proteins. 3) The nucleus has a similar function to the brain of the body. The nucleus controls the cell and the brain controls the body.
The two organelles I picked were the ribosome and the Golgi. The ribosomes work to produce and make proteins. The Golgi takes enzymes and attaches them to the proteins from the ribosomes. These processes work together quite well. The ribosomes don't have to worry about attaching enzymes since the Golgi already took care of the job. These two organelles could be compared to the digestive system of the human body. The digestive system helps the body by doing specific tasks. These processes can's go on when something fails to do its job. -K.B
The endoplasmic reticulum is the internal membrane system in cells in which components of the cell membrane are assembled and some proteins are modified. The cell membrane is thin, flexible thing around a cell, and it regulates what enters and leaves the cell. They both regulate like the nervous system so that has the most similar functions then all the other organelle systems.
The ribosome is an organelle. IT is where proteins are made. ANother organelle is the nucleus. THat is the brain of the cell. They all have to work together in order for the cell to work. The organelles are lke muscles. They are like muscles.
The two organelles that i chosen are ribosome and a golgi. the ribosome is a cell struture that uses genetic instruction to transport amino acid and the they become protiens A golgi is a stock of membrane in the cell in which enzymes attach carb and lipids to the protien
how do they work together well her you go Ribosomes produce the proteins and the gogli apparatus exports the proteins to wherever they are needed.
ribosomes work in the cells of the body golgi are simalar
JR: Two organelles that a cell must have in order to survive, also to coordinate various activities and work in a system is a nucleus and a ribosome. The nucleus’s job in the cell is to organize genes and store them on chromosomes. Another job of the nucleus is to replicate the strands of DNA, also to produce messenger RNA that can be used in the ribosomes. The ribosome is a complex RNA and protein. The ribosome’s job is to assemble proteins. The nucleus and the ribosomes work together to produce proteins. First in the nucleus, the DNA is replicated, and then the messenger RNA picks it up. The mRNA drops it off at the ribosome. There it is matched up with amino acids, resulting in a protein chain. The nucleus controls what happens in a cell as the brain controls what happens in the body.

1)Golgi is an organelle found in most eukaryotic cells.
Nucleus is a membrane-enclosed organelle found in most eukaryotic cells.
2)They both are in the eukaryotic cell.
3)The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene.
The Golgi apparatus is integral in modifying, sorting, and packaging these substances for cell secretion (exocytosis) or for use within the cell.
