Analogy- In a restaurant the building itself supports the restaurant. It is often made of wood or concrete.
Cell Membrane- The cell membrane is a structure that forms the outer boundary of the cell and allows only certain materials to move into and out of the cell. Food, oxygen and water move into the cell through the membrane. Waste products also leave through the membrane. Analogy- In a restaurant the doors are responsible for letting people in and letting people out.
Golgi Bodies- In cells, structures called Golgi Bodies are stacks of membrane-covered sacs that package and move proteins to the outside of the cell. Golgi bodies are the packaging and secreting organelles of the cell.
Analogy- In a restaurant to-go boxes are made to take food outside of the restaurant.
Vacuole Membrane- This is the thin layer that separates the vacuole from the cytoplasm. This thin membrane allows materials to move in and out of the vacuole.
Analogy- In a restaurant the door of the freezer locker allows the cooks to go in and take out food to cook. Vacuole- Within a cell, a vacuole serves as a temporary storage space for the cell. Vacuoles store water, food, pigments, waste or other materials.
Analogy- In a restaurant the purpose of the freezer locker is to store the food temporarily.
Nucleus- The largest organelle in the cytoplasm of a eukaryotic cell is usually the nucleus, a structure that directs all the activities of the cell. The nucleus contains genetic blueprints for the operations of the cell.
Analogy- In a restaurant the manager is in charge of telling their employees their duties in the restaurant. Endoplasmic Reticulum- A folded membrane that moves materials around in the cell. The ER extends from the nucleus to the cell
