A system is a set of connected things or parts that form a whole.In order for a system to function properly, the individual parts must work together.Sometimes, the parts create a product; other times, they make something happen. A cell is a system that creates a product,protein. I will use the analogy “ A cell is like a restaurant,” to better explain how the parts of the cell system work together.
If a cell was a restaurant the cell wall would be like the walls of the restaurant because the walls protect the restaurant from the outside and gives shape to the restaurant in the same way the cell wall protects,supports,and gives shape to the cell. The cell membrane would be like the doors of the restaurant because the doors allow people to go

in and out of the restaurant in the same way the cell membrane controls the passage of materials in and out of the cell. The nucleus is like the manager of the restaurant because the manager controls the rest of the staff in the same way the nucleus controls genetic information (DNA) and is the control center of the cell.
The ribosomes are like the chefs of the restaurant because the chefs produce food for the patrons of the restaurant in the same way that the ribosomes link amino acids to form proteins in the cell. The Endoplasmic Reticulum is like the kitchen in the restaurant because the kitchen is where food is produced and cooked in the same way that the endoplasmic reticulum helps in the cell. The mitochondria/chloroplast is like the stove and oven in the restaurant because the stove and oven produced the energy for the food to cook and bake in the same way that the mitochondria supplies energy for the cell to use. The cytoplasm is like the dining room of the restaurant because the dining room allows the customers and other staff to move around and have space to sit in the same way that the cytoplasm allows molecules to move around the cell. The golgi apparatus is like the waiters of the restaurant because the waiters put in the order for a dish,receive it, and then carry it out from the kitchen to deliver to the customer in the same way that the golgi apparatus
processes,sorts,and delivers proteins in the cell. The lysosome is like the janitor of the restaurant because the janitor cleans up messes and throws away trash in the same way that lysosome gets rid of the cell unwanted material. The vacuole is like the fridge in the restaurant because the fridge stores food to be used later in the same way that the vacuole stores materials such as water and salts needed by the cell. As you can see, a cell is like a restaurant. Just as the organelles in a cell each have a specific job to do, so do the parts in a restaurant. If one part or organelle does not function, the complete system breaks down.
The building of the grocery store is like the cell membrane, because it gives it structure and keeps everything inside safe. The security guard of the front door in the grocery store is like the cell membrane, because it says what can come in and out of the cell. The boss of the store is like the nucleus, because they tell the employes what to do and what needs to be done. The floors of the grocery store is like the cytoplasm, because it hold everything in it place, where it need to be. The illes in the store is
Chloroplasts are and organelle that contains chlorophyll, and is the place where photosynthesis takes place. In a basketball stadium, the concession stands are like chloroplasts. The concession stands is like chloroplast because it makes food for everyone at the game. This is how chloroplasts and the concession stands are alike because they both make food.
to construct and or maintain the cell membrane. In a microscopic view of the cell membrane we can
The immune system is one of the major systems of the human body. It protects the body from diseases and infections that could cause harm to a person’s body. To protect the body it distinguishes between unhealthy and healthy cells (National Institute). The immune system distinguishes between these cells to determine if the body is being invaded by a disease, or if the body is fine and healthy. It will fight off foreign contaminants if they are invading the body to potentially harm it. The immune system works to suppress any unwanted cells, microbes, etc. Without a proper working immune system, the human population would constantly be sick.

There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life.
The body is composed of cells. Normally, these cells divide at a composed and calculated manner. If cells die or are destroyed, the body creates more cells through the division of existing cells. However, occasionally, problems with some cells in the body may occur.
The mitochondria produces food for the cell by converting energy the cell needs. The mitochondria and the nucleus are two organelles within a cell that have many of the same similarities. Both organelles are made of two membranes. These layers isolate within the organelle all things considered, yet have protein channels that permit things to go in and out. Both contain DNA material that conveys qualities that encode for proteins. Both have qualities that make ribosomes, the machines that read the guidelines in RNA to make
Cells are able to grow and reproduce. Cells reproduce by splitting and passing on their genes (hereditary information) to Daughter cells. The nucleus always divides before the rest of the cell divides. Therefore each daughter cell contains their own nucleus. The nucleus controls the cells activities through the genetic material DNA. The cells in a body are all the same except the gametes they were all made from one cell, the Zygote. This is the cell that was formed when two gametes from your parents fused.
The mitochondria is an organelle which is generally an oval shape and is found inside the cytoplasm and is again apart of the eukaryotic cells. The main function of the mitochondria is to complete cellular respiration; in simple terms it acts like a digestive system to break down essential nutrients and to convert it into energy. This energy is usually found to in ATP which is a rich molecule taken from the energy stored in food. Furthermore, mitochondria stores calcium for signalling activities; such as heat, growth and death. They have two unique membranes and mitochondria isn’t found in human cells like the red blood cells yet liver and muscle cells are filled entirely with mitochondria.
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. But it also contains highly organized physical structures which are called intracellular organelles. These organelles are important for cellular function. For instance Mitochondria is the one of most important organelle of the cell. Without Mitochondria more than 95% of the cell’s energy, which release from nutrients would cease immediately [Guyton et al. 2007].
Cell membranes are selectively permeable which can let things in and kick some out. The cell membrane is liquidly and is made out of different things like a mosaic. That’s how the cell membrane got its name fluid mosaic model. The fluid mosaic model of the cell membrane has a different mixture of phospholipids, cholesterol, and proteins. The carbohydrates are attached
The Animal Cell is a little bit different than the Plant Cell for only a couple of reasons. One is how the Plant Cell has a cell wall and the Animal Cell doesn’t. The cell wall protects and gives structure to the cell. Then there is the Nucleus, which serves as a control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the Cytoplasm. This is the watery material lying within the cell between the cell membrane and the nucleus. The Cytoplasm also contains organelles, which have specific functions in the cell metabolism. Then there are the Golgi Bodies, which serve as processing, packaging, and storage for the cell. These organelles package and ship things out. Another parts of the cell, a very important one in fact, are the Lysosomes. These organelles are used to break things down and contain enzymes.
This report provides an insight into the differences in the structure of cells and the way that they carry out their internal mechanisms. Cells form the basis of all living things and they are the smallest single unit of life. Cell biology is the study of cells and how they function, from the subcellular processes which keep them functioning, to the
What is the cell cycle? It’s the way we reproduce. A series of events lead up from the beginning that which gives them life to the splitting of cells, The separate steps make up this very important process. Without the division of cells, we simply would not be here today.
