Greetings World The Earth Says Hello for it is full of life. Today we’re gonna talk about CELLS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Cells are our little babies that make every itty bitty nitty gritty teeney weeney tiny part of our bodies. These bad boys consist of the main following attributes:

1. Nucleus- Contains all genetic information that sustains life. This cool guy is the “daddy” or “mummy” of everything else. He codes some cool guys called *insert deep voice*…Proteins. These guys make other resourceful units that keep the cell going.
2. Cell Surface Membrane- This guy controls things that go in and out and is made up of phospholipid bilayer.
3. Mitochondria- T&TEC of the cell by powering the whole system together.
4. Lysosomes- “Clean up Crew” , removes all cellular debris and dangerous toxins, poisons.
5. Rough ER- Helps makes proteins as well as post translation modification occurs here
6. Smooth ER- Lipid metabolism, Fat synthesis and Cholesterol control.

I hope you enjoyed my cells in a Nutshell
