okay so we're back in the BIOS 13-hundred lab today we're going to be looking at the cell model okay so to start off let's start from the outside here so this blue smooth structure is going to be the smooth endoplasmic reticulum so you can five minutes throughout the cell this is gonna be where lipids and hormones are produced in contrast they smooth the blue surface that is not smooth with these red little structures on it which are ribosomes this is called the rough endoplasmic reticulum and this is going to be the site of protein production you can also find that throughout a cell these orange structures that are most kidney bean-shaped these are going to be the mitochondria where ATP is going to be produced the yellow structures are going to be are peroxisomes and these are going to aid in fatty acid breakdown you Brown structures are our lysosomes these are like our garbage men in the cell they contain enzymes that are going to break down substances within the cell we also have free ribosomes which is the structure here this is also going to be a site of protein production when you move to this pink structure which are the centrioles and this blue structure is going to be the nucleus and on the nucleus these dark blue circles these are going to be nuclear pores where RNA can enter or or exit the nucleus within the nucleus the white structure is our nucleolus which in short is going to make ribosomal subunits and then the brown substance is going to be chromatin Oh okay in addition we also have the Golgi apparatus here so proteins from the rough endoplasmic reticulum or free ribosomes are sent to the Golgi apparatus and this is like the mail packaging system of the cell so it's going to take in proteins modify them and package them up and secretory vesicles and they can exit the cell via exocytosis meaning it leaves the cell and things can also be taken in the cell via endocytosis such as this right here where it shows engulfing something and bring it into a cell
