I think organelles are sort of like classrooms because they make up the school/cell and can be specialized for one particular subject/function.

I think the nucleus is like the principal of a school because they are both in charge and control everything that goes on in the cell.

The nucleolus is like a teacher because it is a subdivision of the nucleus/ principal and is controlled by it.

Vacuoles are like cubbies that can be used to put away and store various materials.

I think vesicles are like backpacks because they allow materials to be stored and easily moved

Lysosomes are like scissors because they both cut down molecules/paper to make them easier to use.

The cytoskeleton is like school walls that help protect the school and maintain its shape.

Microfilaments are like a school bus that helps cells move from one place to another.

I think centrioles are like school campuses which separate one school from another.

Ribosomes are like a roll call paper that sorts every student into a different class and forms different student bodies.

The cafeteria is like the end opossum reticulum because it is where the food is assembled

The Golgi Apparatus could be compared to websites like BlackBoard because they allow students to organize and sorts their grades and assignments.

Tables split the class into smaller groups.

The school gate shapes and protects the school just like the cell wall shapes and protects the cell.

The school security guard controls what goes in and out of the school just like the cell membrane controls what goes in and out of the cell.

The sidewalk around the school separates it from its surroundings.

The school's campus contains the school's contents just like the cytoplasm contains the cell's contents.
