CELLS! :O

       Hey guys, so as you know this is a science blog we are going to talk about science! Who would have thought, right? Today our topic is cells. Did you know you are made of cells? Well mostly everything living is made of cells. 

       What is a cell?  Well a cell is structural unit and we are made of them. Basically everything alive is made of them. They come in all shapes and sizes and have jobs to do. They are so small we can only see most of them through a microscope.          
       There are 2 kinds of cells, prokaryotic and eukaryotic.  Prokaryotic cells have no cell membrane and less structures inside.They are also only one celled organisms, like bacteria.   Eukaryotic cells are the type we our made of because they are multicellular and  have a membrane. Both animal and plant cells are eukaryotic.

        Left are the plant organelles, right are the animal organelles.

        There are animal and plant cells.  They have relatively the same organelles. Organelles are the structures found inside of cells. Plant cells have a cell wall instead of a membrane.  The animal cells have a membrane.  As you know we are animals, so we are made of animal cells.  Plants are made of plant cells and there are more types of cells, like fungi cells...  I am only going to talk about the animal and plant cell. 

      All organelles have jobs to do for the cell.  The cell is kind of like a factory with different stations/organelles to get different things done.  But of course the factory has to have a wall like a protector, well so do cells.  Cell membrane protects cell from the outside and controls what goes in and out.  Cytoplasm fills up the cell.  Its a jelly-like material that holds everything in its place (in the cell).  Of course these workers/organelles need a boss and in this case its the nucleus of the cell.  The nucleus controls all the organelles and the entire cell.  It gives orders and also holds the DNA.





       There are more organelles in the cell, like the mitochondria.  The mitochondria is the shape of a kidney bean and acts as the power unit.  It breaks down the food and releases the energy.  Protein is food for the cell.  The organelle that makes the protein, are the ribosomes.  




        The lysosomes of the cell also breaks down food but it acts as more of a janitor.   It breaks down cell waste and worn out parts.  But where are all the materials held?   Well the answer is in the vacuole.  The vacuole hangs onto the water, waste products and food until they are needed.








      Chromosomes are the structures, where the DNA and some protein is found. The endoplasmic reticulum/ER works as a packaging unit of the cell.  It works with the golgi bodies and the ribosomes of a cell.  There are 2 different types of ERs the smooth and the rough.  The smooth acts as a storage organelle.  The rough ER package the protein.  I have already told you what the ribosomes are but you must be confused on the new organelle, the golgi bodies.  They help with the packaging of the protein. 

Here is a link for more about plant and animal cells. Its kind of long but explains and gives details for a lot.
