Cells by Marty

Here is a picture of an animal cell.  

All living things are made of cells.  Cells are what makes life?  A human has 32.7 trillion cells. Are there different amounts of cells in each human?  Cells are the building blocks of life.  What are the building blocks of cells?  The most important parts of a cell are the plasma membrane, organelles including a nucleus and a mitochondria and ribosomes.  All the organelles are surrounded by cytoplasm.   What do organelles do?   

The nucleus is the most important part of a cell.  The nucleus helps the cell form and grow.  It helps make things move in a cell. 

The cytoplasm fills the cell with a fluid made up of salt and water. It contains organelles. It is in the cell membrane.

The cell membrane controls the in and out of the cells.  The cell membrane protects the cell from from the surroundings. The cell membrane holds proteins. 

Centrosome It serves the cell in the center.  A centrosome can push another centrosome so that centrosome can be made.  It collects microtubule. 

Ribosomes are what give cells energy.  They float around in the cytoplasm.   They bound in the reticulum (ER). 

Golgi body  collects molecules and takes them out of the cell.  It also puts the molecules in vessels.  It creates lysosomes to help things digest.  

Mitochondria it is what keeps our cells alive.  Cells use mitochondria.   mitochondria creates a chain of electrons.  

Vacuoles  collect food for the cells.  It protects the cell from the outside.  They also collect products that have been wasted. 

The nuclear membrane lets a little bit of ions and proteins in the nucleus.  It helps things pass through the nucleoplasm and the cytoplasm.   It controls movements. 

Nucleolus it creates subunits for the proteins.   It takes the proteins to the cell.  It holds people's genes. 

The thing I find most interesting about cells is that they are really small, but they have a lot of room. I find interesting that cells are the reason for life to exist.          

  

Three interesting facts about cells.  They are the building blocks of life. The most important part is the plasma membrane. Cells are too small that they can not be seen with a naked eye.

I think cells are really important because they are what keeps life alive.  Cells are what people should all learn about.
