What makes unicellular organisms unique and simple?
They can do all life process as one cell.
They can fly and eat at Zaxby’s.
They can survive working with other single-celled organisms.
Why do multicellular organisms need so many cells?
They need specialized cells to survive. Specialized cells perform a specific job/function.
They need many cells to all do the same job/function.
They need many cells to have a dancing cell party.
What is the difference between multi-celled and single-celled’s organisms?
Single-celled organisms are “simple” and multi-celled organisms are “crazy.”
Single-celled organisms are “super” and multi-celled organisms are “complex.”
Single-celled organisms are “simple” and multi-celled organisms are “complex.”
True or False:
Single-celled organisms are able to live as one cell, and multi-celled organisms need many cells to live because each cell has specialized job.

What is the main function of the respiratory system?
It converts food into simpler substances for the body to absorb as nutrients and gives the body energy.
It supplies the blood with oxygen in the lungs, and removes carbon dioxide from the body into the atmosphere.
It allows the body's internal and external organs to move so that they can do their jobs.
It helps the heart communicate with the brain.
What is the main function of the muscular system?
It helps the heart communicate with the brain.
It converts food in simpler substances for the body to absorb as nutrients and gives the body energy.
It supplies blood with oxygen in the lungs, and removes carbon dioxide from the body into the atmosphere.
It allows the body to move when attached to the bone. It also allows movement in internal organs, such as heart and intestines.
