A Cell: The Many Parts Of A Cell

There are many parts of a cell, they all have specific duties, and are all

* Cells allow things to go in and out of the organism (allows diffusion to happen so good things go in and bad things go out)

The plasma membrane surrounds all eukaryotic and prokaryotic cells. Eukaryotic cells have membrane bounded organelles whereas prokaryotic cells do not. The plasma membrane forms the boundary between the cell cytoplasm and the environment. Its function are to allow different environments to be established inside and outside the cell. It also controls the movement of substances into and out of the cell.

is something that lets some things in and some things out of the cell. It is an outer cover for the cell. If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It is composed of a thin, double-layered sheet of lipids, around the Cell and is a protective membrane layer around every Cell.

A cell membrane regulates what enters and leaves the cell. It is like a gate in a city because it regulates who comes in and goes out of the city. A nucleus is the control center of the cell. It is like a police department because the police control how everyone and everything acts. A ribosome synthesizes proteins for the cell. A ribosome is like a factory that produces stuff for construction workers. The ER synthesizes lipid membranes and proteins and transports stuff. It is like a manufacturing plant because it makes stuff just like the ER.

There are a few organelles that exist in all three types of cells. The first of these is the cell membrane (also known as the plasma membrane). The plasma membrane is the outer boundary of the cell that protects the cell from its surroundings. It is selectively permeable because it controls what enters and exits the cell. Carl Naegeli and C. Cramer discovered the plasma membrane in 1855.

These parts are all paired to parts of cells. A quarterback is compared to a ER because it throws the whole game when he throws the ball. A cell wall is compared to the center because it protects the quarterback to throw the ball. A football field is compared to the cytoplasm because it is where all the players are at. A coach is like the nucleus because it controls the plays and tells the play. A golgi apparatus is compared to the running back because it sends the

Cell Membrane: Cell boundary that controls what enters and leaves the cell. The cell membrane at Bryant-Denny Stadium is security.The cell membrane at Bryant-Denny Stadium is security because it stops whatever comes and and controls what comes in.They are similar because they do the same thing letting things in and letting things out.

All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support of the cell. A cell membrane is similar to the walls surrounding your house.

In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.

The membrane is a selective barrier, meaning that it can let in certain things and block out other things. This allows nutrients into the cell, and keeps things such as bacteria out. The membrane also allows waste products to pass out of the cell. Each organelle in a cell also has their own membrane. These membranes are all selective barriers as well, determining what can enter and

The elevator in the building is like a rough ER which transport protein from place to place just like the elevator transport the people inside the building from places to places. The president or CEO is like a nucleus; he control everything in his building, just like a nucleus is control center of the cell. The vice president is the nucleolus, which help to synthesis the production of the company, like the nucleolus is the site of ribosome synthesis. The people are the ribosome, they moved from one place to another using and creating work while the ribosome created protein for the cell. The restaurant in the building is like a mitochondria which produce energy through the cellular respiration by providing food for the people in the building. The bacon in the fridge are like the smooth ER which creates fat in the customers when they eat it. The swimming pool in the building is like a cytoplasm, which help suspended the people in it like the cell in which the organelles are suspended. The mail office in the building is like the Golgi bodies in the cell, it helps synthesis, packages and send it content all over

Cell Membrane A cell membrane protects the structures within the cell. Cell membranes are semipermeable, meaning that only certain objects are able to pass through them 6. Cytoskeleton The cytoskeleton is a network of protein fibers that provide the framework for cellular movement, shape, organelle movement and cell division. 7.

The cell wall is like a bodyguard it has the say on who can come in or go out and is like the structure holds the cell. You may be thinking what does the cell wall do well.Cell membranes surround every cell you will study.Wall it protects the cell it also lets it grow great heights. If a plant cell is like a water balloon, the cell wall is like a cardboard box that protects the balloon. The balloon is protected from the outside world

Nucleus- “the brain” or control center of the cell. The Nucleus, a membrane-bound structure of a cell, plays two crucial roles in controlling the cell. The nucleus carries the cell's genetic information that determines if the organism will develop, for instance, into a tree or a human; and it directs most cell activities including growth, metabolism, and reproduction by controlling protein synthesis. The presence of a nucleus distinguishes the more complex eukaryotic cells of plants and animals from the simpler prokaryotic cells of bacteria and cyanobacteria that lack a nucleus. The nucleus is the most predominate structure in the cell. It is typically round and occupies 10% of the cells total volume. The nucleus is wrapped in a
