Cell Analogy
A Cell is like a Family Reunion...
A Grandmother is like a vacuole...
Grandmothers always bring lots of foods and drinks to the reunion, like a vacuole stores food for the cell to use.
The host is like the nucleus...
A host keeps everyone in check and makes sure that nobody gets lost and everyone has a place to sleep, like a nucleus that gives out directions to all the organelles.
The Italian Auntie is like ribosomes...
Although you've only met her twice in your lifetime, your Italian Aunt will make sure that you intake every food containing protein at the reunion, like the ribosomes produce the necessary proteins to make the cell function.
The bedroom is like the cell membrane...
The bedroom can control who comes in and goes out of your own personal sanctuary, and it keeps you safe from all your evil family members. The cell membrane does the same by keeping out all the unnecessary molecules and protecting the cell.
The germaphobic cousin is like a lysosome...
The germaphobe is something every family has - they pick up trash and constantly clean everything - much like the lysosomes in a cell that break down food and waste molecules.
The little kids are like the mitochondrion...
The children at the reunion are balls of non-stop energy, and they spread entertainment throughout the house. This is similar to the mighty mitochondria that provides ATP energy for the cell.
The house is like the cell wall...
The house keeps everyone in and provides protection from the weather and the outdoors, like the cell wall protects the organelles in a cell.
The nagging is like the cytoplasm...
Nagging and bickering always fills the air at a family reunion, much like the cytoplasm fills the cell with fluid.
