we pass through the cell membrane. The cell membrane is like the traffic lights for the cell, the cell membrane regulates what can enter and exit the cell.
Now we come to the boss of the cell- the nucleus. The nucleus runs the cell and controls all activity in the cell.
You can see a layer over the nucleus, this is called the nuclear membrane. The nuclear membrane is like the office of the nucleus, The job of the nuclear membrane is to protect the nucleus.
As we move around the nuclear membrane you can see many little holes on the membrane these are called nuclear pores. The nuclear pores allow molecules to enter or exit the nucleus.
Now inside " the boss" nucleus is a structure called the nucleus. Which is the largest structure in the nucleus, it serves as the site of ribosome synthesis and assembly.
Moving on through the cell we come to the " mighty" mitochondria; the job of the mitochondria is to create energy for the cell. The main energy of the cell is a long word adenosine triphosphate or ATP. ATP is used for moving molecules in the cell and supplying the energy that let the various parts of the cell to work.
Across from the mitochondria you can see a complex maze structure around the nucleus, which is the Endoplasmic reticulum or ER. The ER is in charge of the processing and transport of proteins from one cell to another. The ER has two regions- Rough "ER" If you look closer is covered with ribosomes.
Ribosomes are the workers in the cell that build the proteins.
The second region of the ER is called smooth "ER" because it isn't covered with ribosomes.
Moving away from the ER we come the vesicles. A vesicle is a structure mostly liquid that transports materials within the cytoplasm ( substance in the cell) also called liposomes. Vesicles are like the taxies in the cell.
Right next to the vesicles is a large noodle structure called the Golgi apparatus or Golgi body. The Golgi body is considered the shipping department of the cell. It modifies proteins and prepares them for shipping either outside the cell or to different places in the cell.
Next we see a tube like structure call the centriole. The centriole plays an important role in the cell. Located near the nucleus, the centriole is in charge of cell division and like a secretary keeps the cell running smoothly.
Finally last but not least we now see the lysosomes. Lysosomes act as the clean up crew of the cell. Their job is to break down all kinds of molecules in the cell.
Here is the exit, I hope you all enjoyed your tour of the cell and will visit again next week. Have a great day!!
